ABB Residual Current Circuit Breaker with Overload Protection, 40A Current Rating 2CSR255051R1404 DSE201 C40 AC30 - N Blue

ABB 2CSR255051R1404 DSE201 C40 AC30 - N Blue Residual Current Circuit Breaker (RCBO) with Overload Protection provides integrated overcurrent and earth leakage protection in a single compact module. This device is rated for a 40 ampere current capacity and a sensitive earth leakage trip threshold of 30 milliamperes, making it ideal for safeguarding electrical circuits against short circuits, overloads, and earth faults.

The unit is designed for single-pole applications and mounts easily on standard DIN rails for installation convenience. Its trip characteristic Type C thermal magnetic mechanism ensures reliable operation under fault conditions while maintaining stability during normal transient peaks. The toggle switch actuator provides straightforward manual reset capability after fault clearance.

Rated to operate at 240 volts AC, the breaker features screw-type terminals for secure wiring connections. It also includes dedicated supply neutral and functional earth connections for comprehensive protective functionality. The device has a breaking capacity of 6 kiloamperes, enabling it to interrupt substantial fault currents safely. With dimensions of 100 mm height, 69 mm depth, and 18 mm width, it fits well within distribution board setups requiring compact and modular components.

The operating temperature range from -25 to +55 degrees Celsius ensures robust performance across common electrical environments. Additionally, the RCBO conforms to internationally recognized standards including RoHS and IEC for safety, reliability, and environmental compliance.

Typical industrial and commercial applications include electrical distribution in residential, commercial, and light industrial installations, providing both overload and earth leakage protection to help prevent electrical hazards and improve system safety.

The package includes the ABB DSE201 series Type AC RCBO with built-in supply neutral wire and functional earth wire for enhanced fault detection and operational versatility. Designed for single-pole installations with DIN rail mounting.

Equipped with thermal magnetic tripping mechanism for overload and short circuit protection. Boasts a breaking capacity of 6kA for high fault current interruption. Features a toggle switch reset actuator for manual control.

Supports rated AC voltage of 240V AC with screw terminal connection. Operates within a temperature range of -25 °C to +55 °C. Complies with RoHS and IEC standards ensuring quality and safety. Compact dimensions of 100mm height, 69mm depth, and 18mm width enable space-efficient installation.
