Vue d'ensemble
VIOX KCQJ7 motor controllers combine motor switching, overload
protection and phase-loss protection in an IP55 enclosure with
start/stop buttons and status indicators. The range supports motors up
to 18.5 kW at 380 V, with model-specific current setting ranges up to 38
A.
Versions and Features
| Version | Fonction |
|---|---|
| KCQJ7 | Motor start/stop control with overload and phase-loss protection |
| KCQJ7-W | Adds liquid-level relay control for automatic water pumping and draining |
- CJX2s contactor with a matched JD-8 motor protector.
- Front-panel start/stop buttons and circuit-status indicators.
- AC 220 V or AC 380 V control supply options.
- Detachable cover and connector-based wiring for maintenance
access.
Liquid-level control is intended for suitable conductive water
applications such as water tanks and reservoirs. It is not suitable for
low-conductivity liquids such as petroleum or purified water, flammable
or explosive chemical liquids, or high-density sewage.

Configure the motor protector for the motor nameplate current before
commissioning. Frame current, protector adjustment range and motor
operating current are distinct selection values. Motor overload
protection does not replace coordinated short-circuit protection.
Wiring and Dimensions
The supplied sheet shows KCQJ7 and KCQJ7-W circuits with a 380 V main
supply and either 380 V or 220 V control supply. Match the diagram to
