Super Energy-Saving
In the working state, the contactor needs to be powered for a long time to keep the coil energized. During this process, a large amount of electrical energy is consumed. The B series contactor, with its optimized electromagnetic system, greatly reduces the holding power of the contactor.
Reduced size by 20%
The width of the B series contactor is much smaller than that of traditional contactors, saving installation space for users, and it can be conveniently installed in standard distribution boxes.
Premium Material Selection
The foundation of product quality lies in the choice of raw materials. The B series contactors are made from carefully selected raw material suppliers, both domestic and international, to achieve reliable quality through premium materials.

KNOWLEDGE About Modular Contactor
What is a Modulārais kontaktors?
A modular contactor is an electromechanical switching device designed for DIN rail mounting in distribution boards. It’s used for remote control of lighting, heating, ventilation, and other electrical loads in residential, commercial, and industrial applications.
Key Contactor Components of Modular Contactor
Modular contactors consist of three primary components that work together to control electrical circuits:
Coil: The electromagnetic core of the contactor, responsible for generating the magnetic field that operates the device. When energized, it creates the force to move the contacts.
Contacts: These are the physical connection points that make or break the electrical circuit. Modular contactors typically feature main contacts for power switching and auxiliary contacts for control and signaling purposes.
Enclosure: A compact, modular housing designed to fit on DIN rails, providing protection and easy installation. The enclosure often includes terminal connections for wiring and may feature a manual override switch for testing or emergency operation.
Modern modular contactors may also incorporate additional elements such as arc suppression technology, electronic control modules for enhanced functionality, and built-in surge protection to improve performance and safety in various applications
Modular Contactor Operation Principles
Modular contactors operate through a straightforward electromagnetic mechanism designed for efficient and reliable circuit control. At their core, they consist of three main components: a coil, contacts, and an enclosure. When the coil is energized by a control voltage, it generates a magnetic field that pulls the movable contacts toward fixed contacts, completing the circuit and allowing current to flow to the connected load. Upon de-energizing the coil, the magnetic field collapses, and a spring mechanism pushes the contacts apart, breaking the circuit.
This mechanism enables modular contactors to handle high-power circuits using low-power control signals. They are available in Normally Open (NO) or Normally Closed (NC) configurations, providing flexibility for different applications. Their rapid open-and-close action ensures precise switching, making them ideal for managing lighting systems, HVAC units, and motor loads in residential, commercial, and industrial settings.

Four main families of modular contactors cater to specific applications:
Domestic contactors for peak/off-peak hours and heating circuit switching
Motor control contactors with extended contact life for frequent operations
Reversing contactors combining standard units with mechanical interlocks for power supply reversal
Safety contactors utilizing mirrored contacts to indicate position, often in emergency shutdowns
These specialized types enable precise control in various scenarios, from residential energy management to industrial motor control and safety systems.
Compact and Modular Design of Modulārais kontaktors
Modular contactors are characterized by their compact, standardized design optimized for efficient installation and space utilization. Typically measuring 18-54mm in width for 2-4 pole configurations, these devices are significantly smaller than traditional contactors, allowing for higher density in electrical panels. Their construction features a durable plastic or metal enclosure with integrated DIN rail mounting clips for easy installation.
Key physical attributes include:
Standardized dimensions compatible with DIN rail systems
Modular expansion capabilities for auxiliary contacts and timer modules
Touch-safe terminal designs to reduce accidental contact risks
Advanced terminal configurations like cage clamp technology for secure wire retention
Integrated arc suppression chambers to extend operational lifespan
Optional manual override switches for direct control
These physical characteristics enable modular contactors to offer superior flexibility and safety in a wide range of electrical control applications, from residential lighting systems to industrial motor controls.
Modular vs Traditional Contactors
Modular contactors and traditional contactors differ significantly in size, efficiency, and application. Modular contactors are up to 70% smaller than their traditional counterparts, with some models as narrow as 18mm for 2-pole configurations. This compact design allows for efficient space utilization in electrical panels, making them ideal for residential and small commercial settings where panel space is limited.
In terms of energy efficiency, modular contactors employ energy-saving coils that consume only 0.5-2W of holding power, compared to the 5-10W required by traditional contactors. This reduced energy consumption makes modular contactors more cost-effective for residential use. Additionally, modular contactors offer greater versatility, capable of handling both AC and DC circuits, while traditional contactors are typically designed for specific circuit types. The ease of installation and integration with modern electrical systems further distinguishes modular contactors, making them a preferred choice for applications requiring frequent updates or modifications.
Selecting the Right Contactor
When selecting the right modular contactor for your application, consider these key factors:
Load requirements: Determine the electrical load type (resistive, inductive, or capacitive) and rating. For motors or transformers, factor in inrush current, which can be 5-10 times the normal operating current.
Voltage ratings: Ensure the contactor’s voltage rating matches or exceeds your system’s operating voltage for both the main circuit and control circuit.
Contact configuration: Choose the appropriate number of poles (typically 1-4) based on your system requirements (e.g., single-phase, three-phase).
Operating environment: Consider factors like temperature, dust, moisture, and vibration that may affect the contactor’s performance or require special protection ratings.
Switching frequency: For applications with frequent cycling, solid-state contactors may offer longer lifespans.
Additionally, evaluate the contactor’s electrical and mechanical durability, and consider any specific certifications or standards compliance required for your application. By carefully assessing these factors, you can select a modular contactor that ensures optimal performance and efficiency in your electrical system.
Troubleshooting Common Issues with Modular Contactors
When troubleshooting modular contactors, several common issues may arise. One frequent problem is the contactor failing to close or open, often due to low control voltage or coil failure. Ensure the power supply matches the contactor’s coil voltage requirements, as using the wrong voltage can cause malfunction or overheating. Contact wear is another issue to watch for, indicated by pitting, arcing, or carbon deposits on the contact surfaces. These signs suggest it’s time for maintenance or replacement.
Intermittent operation or excessive noise during switching can indicate mechanical problems or contamination. Regular cleaning and inspection can prevent many issues. For persistent problems, consult the manufacturer’s fault analysis guide and consider professional diagnosis. Remember, safety is paramount when working with electrical components – always disconnect power before inspecting or servicing contactors.
