Eaton xEffect Miniature Circuit Breaker, 3-Pole, 4A, Type D Thermal Magnetic, 415V AC, 10 kA Breaking 278888 FAZ-D4/3

Eaton 278888 FAZ-D4/3 xEffect Miniature Circuit Breaker is a high-quality protection device designed for industrial and commercial electrical control panels. Featuring a 3-pole configuration and a current rating of 4 amperes, it operates at a rated AC voltage of 415 volts with a robust 10 kiloamp breaking capacity for interrupting short circuit faults.

The thermal magnetic trip mechanism provides six levels of reliable overcurrent protection, combining thermal response for overloads with magnetic instantaneous trip for short circuits. The breaker’s toggle switch can be sealed in either the on or off state, enhancing safety and compliance, while the trip-free design ensures that the breaker cannot be held on manually during a fault condition.

This Eaton xEffect MCB has a current limiting design which effectively reduces the let-through energy, protecting downstream equipment from damage. The product’s compact form factor with an 85 mm width and 73 mm depth allows for easy integration into DIN rail mounting systems commonly found within electrical panels.

Clear red and green indicator lights provide visual status of the circuit breaker contacts, improving maintenance and operational assurance. Its IP20 rating offers adequate protection against solid objects in typical industrial environments. While this MCB is suitable for a wide range of industrial, commercial, HVAC, manufacturing, and electrical distribution applications, it is especially effective for supplementary protection of wiring and sensitive circuits.

Reliable 3-pole Miniature Circuit Breaker rated at 4A current. Thermal magnetic trip characteristic, Type D, suitable for inductive loads. Rated for 415V AC and capable of interrupting up to 10 kA fault current. Designed for DIN rail mounting in electrical control equipment.
