Eaton FAZ Series Circuit Breakers

The FAZ series by Eaton offers a wide range of quality, highly reliable and safe circuit breakers. Eaton’s FAZ DIN rail mountable circuit breaker is designed for use in control panel applications.

Features and Benefits

• The Eaton miniature circuit breaker has a current limiting design, providing short circuit interruption to reduce let-through energy, which can damage the circuit.

• Rated currents up to 63A.

• The toggle can be sealed in both the on and off position where required, and the trip-free design means that the breaker cannot be defeated by holding the handle in the on position.

• Reliable and safe operation with six levels of thermal-magnetic over-current protection.

• Red or green light indicates the contact position.

• Easy installation.

• Suitable for supplementary protection.
