2CSR275080R1254 ABB DS201MC25AC30 DS201 M C25 AC30 1P+N 25 A 30 mA Type AC RCBO

Why Choose the ABB DS201MC25AC30 RCBO?

The ABB DS201MC25AC30, manufacturer type DS201 M C25 AC30, is a compact and reliable 1P+N residual current circuit breaker with overcurrent protection (RCBO) designed to provide combined protection against overloads, short circuits and earth leakage faults. As part of the ABB DS200 / DS201 M series, it combines residual current and overcurrent protection within a compact DIN-rail device for single-phase final circuits.

This RCBO has a rated current of 25 A, a Type C tripping characteristic and a rated residual operating current of 30 mA. Its Type AC residual current characteristic is designed to detect sinusoidal alternating residual currents, providing residual current protection for suitable conventional AC electrical loads.

With a rated voltage of 230 V AC and a rated short-circuit capacity of 10 kA, the DS201 M C25 AC30 provides robust protection for single-phase electrical distribution applications. Its compact 1P+N configuration helps conserve space in distribution boards while combining overload, short-circuit and residual current protection in one device.

Reliable Protection for Single-Phase Final Circuits

An RCBO combines residual current protection with overload and short-circuit protection in a single device. The ABB DS201 M C25 AC30 monitors the protected circuit for sinusoidal alternating earth leakage currents while also disconnecting the circuit when excessive current occurs because of an overload or short circuit.

The 30 mA residual current sensitivity provides additional protection against electric shock, while the C-curve overcurrent characteristic accommodates moderate starting and inrush currents. The compact 1P+N format makes the DS201 M C25 AC30 suitable for a broad range of single-phase final circuits.

Typical Applications

• Residential single-phase final circuits.
• Commercial electrical distribution boards.
• Industrial single-phase auxiliary circuits.
• Circuits supplying loads with moderate starting currents.
• Circuits requiring 30 mA residual current protection.
• Installations requiring combined overload, short-circuit and earth leakage protection.
