2CSR772440R1325 ABB DS202CRMB32APR30 RCBO 2P APR Type A B32 30 mA 10 kA

Why Choose the ABB DS202CRMB32APR30 RCBO?

The ABB DS202CRMB32APR30 is a compact 2-pole residual current circuit breaker with overcurrent protection (RCBO) designed to protect end-user single-phase circuits against overloads, short circuits and residual earth fault currents. Part of the ABB DS202CR M APR series, it combines overcurrent and residual current protection within a space-saving two-module device for residential, commercial and industrial electrical installations.

This RCBO features ABB's APR Type A residual current characteristic, providing protection against the effects of sinusoidal alternating and direct pulsating earth fault currents while offering increased resistance to unwanted tripping. Its Type B overcurrent tripping characteristic is suited to general circuits with relatively low inrush currents, while its 30 mA residual current sensitivity provides protection against indirect contact and additional protection against direct contact.

With a rated current of 32 A, rated residual operating current of 30 mA, rated voltage of 230 V and rated short-circuit breaking capacity of 10 kA, the DS202CRMB32APR30 delivers dependable combined protection in a compact DIN-rail format. ABB order code 2CSR772440R1325 identifies the DS202CR M B32 APR30 configuration.

Reliable Protection with Enhanced Continuity of Service

The ABB DS202CRMB32APR30 combines miniature circuit breaker and residual current protection functions within a single compact device. It disconnects the protected circuit during overload or short-circuit conditions while also detecting sinusoidal alternating and direct pulsating earth fault currents, providing comprehensive protection without requiring separate MCB and residual current devices.

ABB's APR characteristic is designed to provide an effective balance between electrical safety and continuity of service through increased resistance to unwanted tripping caused by transient disturbances. With resistance to unwanted tripping of 3 kA on an 8/20 µs surge wave, the DS202CRMB32APR30 is particularly useful where improved continuity is required while retaining sensitive 30 mA residual current protection.

Typical Applications

• Residential electrical distribution boards.
• Commercial building electrical installations.
• Industrial electrical distribution systems.
• Single-phase end-user circuits requiring combined protection.
• Circuits requiring 30 mA Type A residual current protection.
• Installations where improved resistance to unwanted tripping is desirable.
• General-purpose circuits suited to a Type B tripping characteristic.
• DIN-rail mounted modular distribution equipment.
