ABB 2CSR255165R1065 RCBO 6A 30mA C-Curve 1P+N 230V AC

With a rated residual current of just 30 mA and a breaking capacity of 6 kA, the ABB 2CSR255165R1065 combines leakage protection and overcurrent protection in a single, compact module. This RCBO safeguards both people and installations against earth fault currents, overloads, and short circuits, making it an essential component for residential and commercial distribution boards.

Overview

The ABB 2CSR255165R1065 is a 1-pole + neutral residual current circuit breaker with overcurrent protection (RCBO). It is engineered for DIN rail mounting and occupies only 2 modular spacings (36 mm width). The device offers a rated current of 6 A, a rated residual operating current of 30 mA, and a C tripping characteristic, providing reliable protection for circuits with moderate inrush currents.

What stands out

• Combined residual current and overcurrent protection in one unit
• 30 mA sensitivity for personal protection against electric shock
• C tripping curve suitable for general-purpose circuits
• High 6 kA breaking capacity for robust short-circuit handling
