KNOWLEDGE About MCB Busbar Connector
What are BUSBAR CONNECTOR FOR MCB
An MCB bus bar connector is a metallic strip—typically made of copper or aluminum—used to create a common connection point for several MCBs. Instead of wiring each breaker individually, the bus bar allows for a single power input to be distributed across multiple breakers, streamlining installation and improving reliability
TB25 and TB50 Series MCB Busbar Connectors
The TB25 and TB50 series are specialized busbar connector families designed for power distribution in electrical systems. TB25 connectors are rated for 25mm² wire capacity with current ratings ranging from 32A to 125A, while TB50 models accommodate larger 50mm² connections for higher power applications. These side feed-in terminals provide efficient connection points for MCB (Miniature Circuit Breaker) busbars, featuring pure copper conductors with fire-resistant PVC insulation.
Available in multiple configurations including TB25-1, TB25-2, TB25-3, and TB25-4, with dimensions typically around 32-49mm × 13.2-17.5mm × 17-18.2mm
Manufactured by companies like VIOX and other Chinese electrical suppliers
Designed for commercial and industrial power distribution applications
Compatible with pin, fork, U, and C45 type busbars for universal MCB connectivity
Provide secure terminal connections while maintaining low contact resistance and good conductivity
MCB Busbar Connectors Advantages
Busbar connectors offer significant advantages for electrical distribution systems, combining practical design with enhanced performance. These connectors feature excellent conductivity with low contact resistance, ensuring safe and reliable power transmission throughout the system. Their design prioritizes quick installation, which substantially reduces labor time and costs during panel assembly and maintenance.
Provides secure terminal connections while maintaining optimal electrical performance
Simplifies wiring in electrical distribution panels, enhancing overall system organization
Manufactured from high-quality materials that ensure durability and longevity
Compatible with various busbar types including pin, fork, and U-type configurations
Meets international standards with certifications including RoHS, CE, and TUV compliance
Offers versatility with multiple configuration options to accommodate different system requirements
Enables more efficient space utilization in electrical panels compared to traditional wiring methods
MCB Busbar Connector Installation Process
Installing TB25 and TB50 busbar connectors requires careful attention to ensure proper electrical connections and system safety. These feed-in terminals create efficient power distribution points for MCB systems with minimal effort when following the correct procedure.
Begin by ensuring all power is disconnected before attempting installation
For TB25 connectors (25mm² capacity), slide the busbar into the designated supports and push fully home until securely seated
When installing TB50 connectors (50mm² capacity), follow the same procedure but ensure adequate space for the larger gauge wiring
Connect incoming power cables to the appropriate terminals, being careful to maintain proper polarity
Tighten all terminal connections to the manufacturer’s recommended torque specifications (typically around 2.3Nm or 20lbf-in)
For split-load applications, ensure the connecting pins properly straddle any blanking tags in the busbar assembly
After installation, verify all connections are secure and properly insulated before restoring power to the system
Double-check that maximum wiring areas (25mm² for TB25 and 50mm² for TB50) are not exceeded to prevent overheating
Manufacturing Methods
The manufacturing of MCB busbar connectors involves sophisticated processes that ensure electrical efficiency, mechanical strength, and safety. The production typically begins with material preparation, where high-conductivity copper (>99.95% purity) or aluminum is selected as the base material. For bimetal composites like copper-clad aluminum, mechanical brushing removes oxide layers before assembly under controlled atmospheric conditions.
Precision Manufacturing: CNC systems integrate cutting, punching, and bending operations with positional accuracy of ±0.02mm, while servo-driven shear presses slice metal stock at rates up to 120 cuts/minute
Insulation Process: After forming, busbars undergo extrusion coating where PVC or thermoplastic elastomer (TPE) insulation is applied, creating layers with dielectric strength rated for up to 5000V
Tratarea suprafeței: Electroplating with tin, silver, or nickel provides corrosion resistance and reduces contact resistance to <10 µΩ
Asigurarea calității: Each busbar undergoes rigorous testing, including current carrying capacity tests (at 125% rated current), contact resistance verification, and environmental testing such as 1000-hour salt spray tests to ensure <5% surface degradation
Modern manufacturing facilities employ automated vision systems that inspect coating uniformity at 200 frames per second, rejecting defects larger than 50 µm to maintain the highest quality standards
Greșeli frecvente de instalare și cum să le evitați
When installing TB25 and TB50 busbar connectors, several common mistakes can compromise system safety and performance. Incorrect alignment is a frequent error where installers fail to properly align the connector with circuit breaker terminals, creating gaps that can lead to dangerous arcing and overheating. This misalignment issue is particularly problematic with TB25 and TB50 series due to their specific dimensional requirements (TB25: 32-49mm × 13.2-17.5mm × 17-18.2mm; TB50: 35mm × 17.5mm × 34mm).
Always de-energize the circuit completely before installation and verify with a voltage tester
Use a torque screwdriver to tighten terminals to manufacturer specifications, preventing loose connections that cause arcing and heat buildup
Ensure proper sizing—TB25 for 25mm² applications and TB50 for 50mm² applications—to prevent overloading
Check for proper alignment before securing connections, as misaligned components create mechanical stress and reduce efficiency
Distribute loads appropriately across circuits to prevent overheating the busbar connectors
Regularly inspect for signs of corrosion, especially in humid environments, and apply protective coatings when necessary
Selecting the Right TB25/TB50 MCB Busbar Connector
When choosing between TB25 and TB50 busbar connectors for your electrical project, several key factors should guide your decision:
Cerințe actuale: TB25 connectors are designed for applications requiring up to 25mm² wire capacity, while TB50 models accommodate larger 50mm² connections for higher power applications
Dimensional compatibility: Verify that the connector dimensions match your installation space – TB25 models typically measure around 32-43mm × 13.5mm × 17mm, while TB50 models are larger at approximately 32mm × 17.5mm × 14.9mm
Configuration needs: Select the appropriate model based on your specific requirements – TB25 comes in variants like TB25-1, TB25-2, TB25-3, and TB25-4, each designed for different connection arrangements
Material quality: Choose connectors made from high-quality brass, which provides good conductivity and low contact resistance for safe and reliable power transmission
Compatibility with existing systems: Ensure the selected connector works with your current busbar type (pin, fork, U-type) and mounting configuration
For optimal performance and safety, always match the connector’s current rating to your system requirements rather than selecting based solely on price or availability.
