2CSR275180R1104 ABB DS201MC10A30 DS201 M C10 A30 RCBO 1P+N 10A 30mA Type A 10kA

Why Choose the ABB DS201MC10A30 RCBO?

The ABB DS201MC10A30, manufacturer type DS201 M C10 A30, is a compact residual current circuit breaker with overcurrent protection (RCBO) designed for protection of end-user single-phase circuits. Part of ABB's System pro M compact DS201 M range, it combines overload, short-circuit and residual current protection within a two-module DIN-rail device.

This RCBO has a 10 A rated current, C tripping characteristic and 10 kA rated short-circuit breaking capacity. Its Type A residual current function responds to sinusoidal alternating and pulsating direct residual currents, while the 30 mA rated residual operating current provides additional protection against electric shock in appropriately designed installations.

The 1P+N configuration provides one protected pole together with neutral switching for single-phase installations. Operating at 230–240 V AC, 50/60 Hz, the DS201 M C10 A30 provides coordinated thermal-magnetic overcurrent and Type A residual current protection for residential, commercial and industrial circuits.

Type A Protection for Single-Phase Circuits

The ABB DS201 M C10 A30 combines the protective functions of a miniature circuit breaker and a residual current device. Its thermal-magnetic overcurrent section protects wiring and connected equipment against overload and short-circuit currents, while its Type A residual current function responds to both sinusoidal alternating and pulsating direct earth fault currents.

With 30 mA residual current sensitivity, the DS201MC10A30 provides protection against indirect contact and additional protection against direct contact in appropriate installations. Its 10 A C-curve characteristic accommodates suitable loads with moderate starting currents, while the 10 kA Icn breaking capacity provides robust short-circuit protection.

Typical Applications

• End-user single-phase electrical circuits.
• Residential electrical distribution boards.
• Commercial building electrical installations.
• Industrial distribution and control systems.
• Circuits with suitable loads that may produce moderate starting or inrush currents.
• Applications requiring combined 10 A C-curve overcurrent and 30 mA Type A residual current protection.
