Description

Type A RCBO Designed for Live Electrical TPN Distribution Boards

The Live Electrical 10kA RCBO 25A Curve B Type A 30mA 1P+N is a combined residual current and overcurrent protective device. It is intended for use in Live Electrical TPN distribution boards, protecting final circuits against overloads, short circuits, and earth leakage—including AC and pulsating DC residual currents.

This RCBO is fully compliant with BS EN 61009-1 and supports safe, code-compliant installations in domestic, commercial, and light industrial environments.


Electrical Characteristics and Applications

Rated at 25A, this device features a Curve B tripping profile, making it suitable for socket outlets, lighting, and mixed-use circuits with low inrush current. The 30mA Type A residual sensitivity ensures timely disconnection in the presence of fault leakage, improving safety against electric shock and fire risk.

Its 10kA breaking capacity allows it to safely interrupt higher fault currents, enhancing circuit protection reliability.


Mounting and Construction

The Live Electrical 25A RCBO has a 1P+N pole configuration, enabling simultaneous isolation of phase and neutral conductors. Designed as a single-module unit, it mounts easily onto DIN rails and fits standard slots within Live Electrical TPN three-phase boards.

The terminals accept cable sizes up to 16mm², supporting standard final circuit wiring.
