Four pole mcb Windsor

The Windsor Four Pole Miniature Circuit Breaker (MCB) is a high-performance protective device designed to provide complete isolation and fault protection across three-phase + neutral electrical systems. It disconnects all four poles simultaneously—L1, L2, L3, and N—ensuring maximum safety during overload or short-circuit conditions in industrial, commercial, and heavy-duty installations.

Engineered with a precision thermal-magnetic trip mechanism, the Windsor 4P MCB delivers reliable protection against excessive current, while its rugged, flame-retardant housing withstands harsh operating environments. This makes it ideal for three-phase machinery, HVAC systems, industrial panels, heavy motors, and distribution circuits requiring full isolation.

Designed for easy integration into standard distribution boards, it mounts securely on a 35mm DIN rail and features a clear ON/OFF indication with a durable, ergonomic switch handle. Its compact, efficient design supports safe maintenance and dependable long-term operation.
