ABB DS301CA-B13/0.03 RCBO 1P+N 13A B Curve 30mA 6kA Type A 2CSR255163R1135

The ABB DS301CA-B13/0.03 combines residual current protection and overcurrent protection in a single 1P+N module, making it a space-saving choice for distribution boards where every DIN rail slot counts. Its B-curve tripping characteristic and 30 mA residual current rating are tailored for circuits with moderate inrush currents and require personal protection against earth leakage.

Highlights

• 1P+N RCBO with 13 A rated current and B tripping curve
• 30 mA residual operating current, Type A (AC and pulsating DC)
• 6 kA short-circuit breaking capacity
• DIN rail mounting with screw terminals

In daily use

This RCBO responds to both overload and earth leakage, reducing the need for separate MCB and RCD devices. The Type A residual current detection covers standard AC faults and pulsating DC components, which is relevant for circuits with electronic loads. With a rated voltage of 230 V AC and 50/60 Hz operation, it fits standard single-phase installations.
