Overcurrent circuit breaker series 15kA 3-pole FAZ-C63/3 278879

Overcurrent circuit breaker – reliable protection for electrical installations

This three-pole overcurrent circuit breaker from Eaton's FAZ-C63/3 series is a key element of every safe electrical installation. Designed to protect circuits against overloads and short circuits, it ensures stable and safe system operation. The rated breaking capacity of 15kA (according to IEC/EN 60947-2) guarantees an effective response in emergency situations, minimizing the risk of damage and fire.

Characteristics and application

The circuit breaker is characterized by a C characteristic, which means it is ideal for circuits with devices generating inrush currents during start-up – such as motors or transformers. This allows you to avoid unnecessary tripping of the circuit breaker during normal operation of these devices, while ensuring rapid intervention in the event of a real hazard. The rated current of 63A makes it suitable for protecting circuits with higher power consumption. Mounting on a TH-35 rail is standard, which simplifies and speeds up installation.

Key features and benefits
