Fusebox INC634 Description
The FuseBox INC634 3 module 63A 230V four pole DIN Rail Contactor is a compact, versatile and reliable switching device designed to provide efficient and remote switching control for a wide range of electrical loads in three-phase installations.
Engineered for seamless integration into distribution boards, allowing the control high-power circuits like large lighting circuits, industrial heaters, or small three-phase motors.
Features four Normally Open (N/O) poles. This allows it to simultaneously switch all three phases and the neutral conductor of a circuit, providing complete isolation for enhanced safety and compliance.
With a 63A current rating (AC-7a), it is well-suited for controlling moderate to high electrical loads, including large lighting circuits, industrial heaters, or small three-phase motors.
3 module (54mm) design taking up just 3 module spaces in the distribution board.
Designed for quick and secure mounting on a standard 35mm DIN rail, ensuring a hassle-free and professional installation.
Supplied with two 9mm heat dissipation spacers - essential for maintaining correct operating temperatures when installed next to other modular devices.
Operates with a standard 230V AC coil, making it compatible with a wide variety of switches, timers, and smart home control systems.
