Overcurrent circuit breaker series 15kA 3-pole FAZ-C4/3 278865

Reliable protection of electrical installations – Eaton FAZ-C4/3 circuit breaker

This three-pole circuit breaker from the FAZ series is a key element of protection in every electrical installation. Designed by the renowned company Eaton, model FAZ-C4/3 with a rated current of 4A and a short-circuit breaking capacity of up to 15kA, provides effective protection against overloads and short circuits. It is characterized by reliability and durability, making it an ideal choice for both professional installers and end users.

Characteristics and application

The FAZ-C4/3 circuit breaker with characteristic C is a universal solution for protecting circuits with receivers with moderate inrush current. It is suitable for protecting lighting, general-purpose sockets and electrical appliances in residential, commercial and industrial buildings. Characteristic C allows for temporary overloads without unnecessary tripping, which is particularly important when starting motors or other devices generating high starting current. The breaking capacity of up to 15kA guarantees safety even in the event of serious short circuits.

Construction and mounting

The Eaton FAZ-C4/3 circuit breaker has 3 poles and is designed to operate at AC 400V. Its compact dimensions – width of 3 modules and installation depth of 70.5 mm – make it easy to mount in standard distribution boards. The degree of protection IP20 provides protection against accidental contact, and the possibility of additional equipment (e.g. auxiliary contact) allows for expanding the functionality of the circuit breaker. The cross-section of the connected solid or stranded wire up to 25 mm² provides flexibility when connecting different types of wires. Energy limitation class 3 minimizes the effects of short circuits, and the rated impulse withstand voltage of 4 kV increases resistance to overvoltages.
