Product information

Description

Residual-current circuit breaker 4P 25A 30mA Type AC Kanlux KRD10-4/25/30-AC is a four-pole residual-current device designed for three-phase electrical installations. It provides earth-fault protection with a rated current of 25 A and a residual operating current of 30 mA (Type AC), detecting alternating sinusoidal leakage currents and disconnecting supply circuits to reduce the risk of electric shock and fire. The device is suitable for residential and light-commercial distribution boards where sensitive protection against ground faults is required.

Advantages

The device offers reliable ground-fault detection for three-phase circuits with a compact four-pole design that simplifies installation in standard distribution panels. With a 30 mA trip threshold it balances personal protection and selectivity for lighting and socket circuits. Type AC operation ensures clear response to AC sinusoidal leakage currents, and the manual test function allows periodic verification of proper tripping behavior. Constructed to industry safety standards, the product integrates into typical DIN-rail switchgear installations.

Suitable for

Three-phase residential supply boards
Small commercial or light-industrial distribution panels
Protection of socket and lighting circuits in multi-phase systems
Complementing overcurrent protection devices in household installations

Key specifications

Poles: 4 (three phases + neutral)
Rated current: 25 A
Residual operating current (trip sensitivity): 30 mA
Type: AC (responds to AC sinusoidal residual currents)
Function: Manual test facility for trip verification
Mounting: DIN-rail compatible housing for distribution boards

How to use

Mount the device in the distribution board on a standard DIN rail according to local electrical codes and wiring diagrams. Connect the three phase conductors and neutral to the corresponding input and output terminals, and ensure upstream overcurrent protection is correctly rated. After installation, use the built-in test button to confirm correct trip operation at commissioning and during periodic maintenance. If the device trips under load, isolate the circuit and inspect for earth faults or wiring issues before resetting.

Usage recommendations

Install and service only by a qualified electrician in compliance with applicable standards and regulations. Test the residual-current circuit breaker regularly (for example, monthly) using the test button and follow the system designer's guidance for selective coordination with other protective devices.
