2CSR255163R1164 ABB DS301C C16 A30 16 A 30 mA Type A 6 kA RCBO

Why Choose the ABB DS301C C16 A30 RCBO?

The ABB DS301C C16 A30 is a compact 1P+N residual current circuit breaker with overcurrent protection (RCBO) designed to protect single-phase final circuits against overloads, short circuits and earth leakage faults. Combining overcurrent and residual current protection within a single-module device helps maximise available space inside electrical distribution boards while providing dedicated protection for individual circuits.

This RCBO has a rated current of 16 A, a C-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 short-circuit protection for appropriately designed residential, commercial, building and industrial installations.

The DS301C C16 A30 operates at a rated voltage of 230–240 V AC at 50 Hz and uses voltage-independent residual current protection. Contact position and earth fault indication assist with device status identification, while terminals accommodate conductors up to 16 mm² and compatible busbars up to 10 mm².

Reliable Type A Circuit Protection

The ABB DS301C C16 A30 combines overcurrent and residual current protection within one compact protective device. It protects its connected circuit against overload and short-circuit currents while its Type A residual current function responds to sinusoidal AC and pulsating DC earth leakage currents. Its 30 mA sensitivity provides additional protection against direct contact as well as protection against indirect contact when correctly selected and installed.

The C-curve characteristic is suitable for appropriate circuits that can experience moderate starting or inrush currents, while the voltage-independent residual current function does not depend on the supply voltage for operation. Combined with a 16 A rating, 6 kA breaking capacity and compact single-module construction, the DS301C C16 A30 provides practical protection where both performance and distribution board space are important.
