ABB 2CSR275180R0165 RCBO 1P+N 16A C Curve 30mA AC Type 6kA 2 Module DS201

Electrical faults and overloads can lead to dangerous situations, damaging equipment and risking personal safety. The ABB 2CSR275180R0165 combines residual current protection and overcurrent protection in a single compact device, ensuring reliable protection for people and installations. This RCBO from the DS201 series detects earth leakage currents of 30 mA and trips instantly, while also protecting against overloads and short circuits with a C-curve characteristic. It is the ideal solution for residential and commercial applications where both safety and space are at a premium.

Who is it for

This device is intended for electricians, panel builders, and facility managers who need to protect final circuits in distribution boards. It is particularly suitable for socket outlets, lighting circuits, and other loads where personal protection against electric shock is required. The 1P+N design with two modules width makes it easy to integrate into standard DIN rail enclosures, saving space without compromising safety.

Tips

When installing this RCBO, ensure that the upstream overcurrent protection is coordinated to avoid nuisance tripping. For circuits with electronic loads that may produce DC residual currents, consider using a type A or B residual current device. Always test the device using the test button after installation and periodically as part of maintenance.
