2CCG001663R0001 ABB FS401E-C10/0.03 RCBO 1P+N Type A 30mA 10A

Why Choose the ABB FS401E-C10/0.03 RCBO?

The ABB FS401E-C10/0.03 is a compact and reliable residual current circuit breaker with overcurrent protection (RCBO) designed to protect single-phase final circuits against overloads, short circuits and earth leakage faults. As part of the ABB SMISSLINE TP plug-in system, it combines overcurrent and residual-current protection in a single 1P+N protective device for residential, commercial and industrial electrical installations.

This RCBO has a rated current of 10 A, a Type C tripping characteristic and 30 mA residual-current sensitivity. Its Type A residual-current detection provides protection against sinusoidal AC and pulsating DC earth fault currents, while the DTI functionality assists with identification of residual-current tripping during inspection and fault finding.

With a 6 kA rated short-circuit breaking capacity according to EN 61009-1, the FS401E-C10/0.03 provides comprehensive circuit protection in a compact two-module format. Its plug-in construction enables straightforward integration with compatible ABB SMISSLINE TP distribution systems, helping simplify installation and maintenance.

Combined Overcurrent and Earth Leakage Protection

RCBOs such as the ABB FS401E-C10/0.03 combine miniature circuit breaker and residual-current protection functions in one device. This enables the protected circuit to be disconnected in response to overloads, short circuits or potentially hazardous earth leakage currents while allowing individual final circuits to be protected independently.

The FS401E series is designed for ABB's SMISSLINE TP plug-in distribution architecture. Type A residual-current detection responds to sinusoidal alternating and pulsating direct residual currents, while the 30 mA sensitivity provides additional protection against direct contact in suitable electrical installations.

Typical Applications

• Single-phase final circuit protection.
• Residential electrical distribution systems.
• Commercial buildings and facilities.
• Industrial electrical installations.
• Lighting, control and general-purpose circuits.
• ABB SMISSLINE TP plug-in distribution systems.
