Product Description

Eaton 278865 FAZ-C4/3 Miniature Circuit Breaker is a 3-pole device rated for 4 amps with Type C tripping characteristics, engineered for robust protection in residential, commercial, and industrial electrical installations. It is designed to safeguard resistive and inductive loads against overload and short circuits, offering reliable performance where moderate inrush currents are expected.

The breaker operates at a rated alternating current voltage of 400 volts AC and a direct current voltage rating of 60 volts DC. It features a high breaking capacity of 10 kiloamperes, which makes it suitable for demanding environments requiring fast and effective fault clearing.

The device is installed via a standard DIN rail mounting system with a slim and efficient width of 52.5 mm per three poles, optimizing panel space. Twin-purpose terminals provide installation flexibility by allowing connections from either top or bottom, simplifying wiring tasks.

Encased with an IP20 rating, the enclosure protects users from accidental contact with energized parts and prevents ingress of objects larger than 12 mm. The circuit breaker is engineered to function reliably within an operating temperature range from minus 40 to plus 75 degrees Celsius, ensuring effectiveness even in harsh conditions.

Thermal magnetic tripping mechanism for immediate response to overloads and short circuits. Compact dimensions of 74 mm depth and 52.5 mm width facilitate integration in control panels. Standards compliance with IEC/EN 60898-1 for overcurrent protection applicable to household and similar installations.

Toggle switch reset actuator provides intuitive manual control for circuit restoration. Ideal for protection in motors, lighting, HVAC, and industrial control systems.

Manufactured in Romania, this Eaton xEffect series circuit breaker combines durability with reliable performance, making it a preferred choice for electrical engineers and technicians. Explore more options for circuit breakers and electrical components in EnvMart’s extended catalog.
