Residual current circuit breaker EFI-4 A 100/0.3 002062154

Protection and safety in your electrical installation

This four-pole residual current circuit breaker (RCCB) with a rated current of 100A and A sensitivity (300mA) is a key element ensuring safety in every electrical circuit. It serves to protect against electric shock, both in the case of direct and indirect contact with live parts. Additionally, it protects devices from damage caused by short circuits or leakage currents. Mounted on a DIN rail, it is ideal for both new installations and for modernizing existing ones.

Versatility and reliable operation

This circuit breaker is designed to operate in TN-S, TN-C-S, TT and IT networks. Its construction based on proven technologies guarantees reliable operation even in difficult conditions. A rated differential current of 300mA makes it particularly recommended for fire protection and protection against indirect contact. The short-circuit strength at the level of 10kA ensures effective protection of the installation in the event of a short circuit.

Comfort of installation and use

The installation of the circuit breaker is simple and intuitive thanks to the standard mounting on a DIN rail. Compact dimensions – a width of 4 modules and a depth of 68mm – allow for easy adaptation to the existing switchgear cabinet. A clear indicator of the contact position facilitates quick identification of the circuit breaker status (ON/OFF), and a test button allows you to regularly check its functionality. The possibility of sealing the lever provides additional protection against unauthorized activation or deactivation of the device. It accepts solid and stranded wires with a cross-section from 1 to 25 mm², which ensures wide compatibility with different types of wires. Operation in the temperature range from -25°C to 55°C guarantees reliable operation even in extreme environmental conditions.
