ABB DSE201 M C16 AC30 electronic RCBO providing 16 A Type C overcurrent protection with 30 mA Type AC residual current protection in a compact one-module DIN rail device.
£151.67
The ABB 2CSR275051R1164, designated DSE201 M C16 AC30 - N Blue, is a compact 16 A Type C RCBO (Residual Current Circuit Breaker with Overcurrent Protection) that combines overload, short-circuit and earth leakage protection in a single DIN rail module. Designed for residential, commercial and industrial installations, it provides dependable protection while reducing the space required within modern consumer units and distribution boards.
Featuring a 30 mA Type AC residual current sensitivity, the device provides additional protection against electric shock and helps minimise the risk of electrical fires caused by earth faults. Its Type C tripping characteristic makes it particularly suitable for circuits supplying equipment with moderate inrush currents, such as lighting, small motors and control equipment.
The DSE201 M series incorporates a flying neutral conductor and functional earth lead, simplifying installation while maintaining reliable residual-current operation. Its compact one-module width enables higher circuit density without compromising electrical safety or performance.
The ABB DSE201 M RCBO protects electrical installations by combining overload, short-circuit and residual current protection within one compact device. During fault conditions it disconnects the affected circuit quickly, helping protect people, wiring systems and connected equipment while reducing downtime.
Its Type C operating curve makes it particularly suitable for circuits supplying inductive loads or equipment with moderate starting currents, while the 30 mA residual current protection provides additional safety against electric shock in accordance with recognised installation standards.
