2CSR255164R1065 ABB DS301CT B6 A30 6 A 30 mA Type A 6 kA RCBO

Why Choose the ABB DS301CT B6 A30 RCBO?

The ABB DS301CT B6 A30 is a compact 1P+N residual current circuit breaker with overcurrent protection (RCBO) designed to protect suitable single-phase final circuits against overloads, short circuits and earth leakage faults. Combining overcurrent and residual current protection within one device helps reduce the space and wiring required inside modern electrical distribution boards.

This RCBO has a rated current of 6 A, a B-curve tripping characteristic and a rated residual operating current of 30 mA. Its Type A residual current characteristic responds to sinusoidal AC and pulsating DC residual currents, while its 6 kA breaking capacity provides dependable short-circuit protection for appropriately designed circuits.

As part of ABB's DS300 RCBO product group, the DS301CT B6 A30 combines a compact 1P+N configuration with DIN-rail mounting for modular distribution applications. Its 6 A B-curve rating is suited to appropriate lower-current circuits with relatively low starting or inrush currents, while 30 mA Type A protection supports circuits supplying modern electrical and electronic equipment.

Reliable Type A Circuit Protection

An RCBO combines residual current protection with overload and short-circuit protection in a single device. The ABB DS301CT B6 A30 therefore provides dedicated protection for its connected circuit while its Type A residual current characteristic detects both sinusoidal AC and pulsating DC earth leakage currents. Its 30 mA sensitivity provides additional protection against electric shock when correctly selected and installed as part of an appropriate electrical system.

The B-curve characteristic is suited to appropriate circuits with relatively low normal starting or inrush currents, while the 6 A rating makes this version suitable for correctly designed lower-current applications. Combined with a 6 kA breaking capacity, the DS301CT B6 A30 provides coordinated overcurrent and residual current protection in a compact modular format.
