Residual Current Circuit Breaker 4P 100A AC Kanlux 23197

Kanlux Residual Current Circuit Breaker 4P 100A AC is a 4-pole residual current device designed to detect alternating earth leakage and rapidly disconnect supply in three-phase installations with neutral. The unit rated for 100 A continuous current provides protection against AC-type leakage currents, improving electrical safety in residential and light-commercial distribution boards. The compact housing fits standard panel mounting and is intended for use where selective disconnection of all live conductors and neutral is required to isolate a circuit following a leakage fault.

Advantages

This 4-pole RCCB offers consistent leakage detection for AC-type faults and ensures simultaneous disconnection of all phases and neutral, reducing the risk of touch voltage on equipment. With a 100 A current rating, it supports higher load circuits commonly found in small commercial and larger residential installations. The device is built to integrate with standard distribution board layouts and provides straightforward electrical safety compliance where earth leakage protection is mandated.

Suitable for

• Three-phase electrical installations with neutral in residential buildings
• Light-commercial distribution boards and small workshops
• Protecting circuits feeding motors, HVAC units, and lighting groups
• Where AC-type residual current detection is sufficient (non-pulsating DC environments)

Key specifications

• Poles: 4-pole design for three-phase plus neutral disconnection
• Rated current: 100 A continuous
• Residual current type: AC (sensitive to alternating leakage currents)
• Function: earth leakage detection and rapid disconnection of supply
• Mounting: panel/distribution board compatible housing

How to use

Install the device in the distribution board according to local electrical regulations and wiring practices. Connect the three phase conductors and neutral to the corresponding terminals and ensure tight, secure connections. The RCCB must be placed downstream of the main overcurrent protection where coordinated protection is required. Test the device after installation using the built-in test function or an appropriate testing instrument to verify trip operation and correct wiring before placing the circuit into regular service.

Usage recommendations

Use this AC-type residual current breaker in installations where alternating leakage currents are expected; avoid use where pulsating DC or high-frequency leakage can occur unless a more suitable residual current type is specified. Periodically test the trip function and inspect terminal tightness as part of routine electrical maintenance to maintain reliable protection.
