Overcurrent circuit breaker series 15kA 3+N-pole FAZ-C16/3N 278975

Three-pole circuit breaker – protection and reliability of the installation

The FAZ-C16/3N circuit breaker is a reliable electrical protection device designed to protect circuits against overload and short circuit. Its 3+N pole design makes it ideal for protecting three-phase installations with a neutral wire. A rated current of 16A combined with characteristic C provides effective protection while minimizing the risk of unnecessary tripping of the device during short-term load surges – which is particularly important when connecting devices with motors or other elements generating inrush currents.

Application and design features

This circuit breaker finds wide application in residential, commercial and industrial buildings. Its compact dimensions (4 module width) allow for easy mounting on a DIN rail in electrical switchboards. The breaking capacity of up to 15 kA at 400V (IEC 60947-2) guarantees safety even in the event of serious failures. Additionally, simultaneous disconnection of the N pole increases the safety level of users by cutting off the power to the entire circuit in the event of a hazard. Made of high-quality materials, it ensures long-lasting and trouble-free operation in a wide range of ambient temperatures (-25°C to +75°C).

Parameters and benefits for professionals

This circuit breaker stands out from the competition thanks to several key parameters. Energy limitation class 3 and surge category III provide high resistance to disturbances in the electrical network. The connection cross-section from 1 to 25 mm² provides great flexibility during installation, allowing connection of cables of different thicknesses. Protection degree IP20 protects against accidental contact, and the possibility of mounting on a DIN rail facilitates and speeds up the installation process. Power losses of only 7.5W minimize energy losses in the circuit. The rated impulse withstand voltage Uimp at 4kV provides additional safety in the event of overvoltages.
