The Fuji SC-4-1 is a high-performance industrial magnetic contactor engineered for heavy-duty motor control and electrical circuit switching. Rated for a conventional thermal current ($I_{th}$) of 20A, this model provides robust power handling for more demanding machinery and automated systems while maintaining a reliable, compact frame. This specific configuration includes 3 Normally Closed (3NC) and 1 Normally Open (1NO) contacts, offering a specialized arrangement for complex interlocking, safety sequences, and signaling requirements within a control panel.

Designed for maximum versatility in diverse electrical environments, the SC-4-1 is available in multiple coil voltage options, including 220V AC, 110V AC, 48V AC, and 24V AC. This allows it to be seamlessly integrated into both standard industrial power systems and specialized low-voltage control circuits. Fuji Electric’s SC series is renowned for its durability, utilizing high-quality silver alloy contacts and a precision electromagnetic core to ensure a long mechanical and electrical service life, even under high-cycle operational conditions.

The SC-4-1 features an ergonomic design with secure screw terminals to prevent loosening from vibration and a front-facing indicator for immediate visual confirmation of the contactor’s state. Its modular construction is fully compatible with standard DIN rail mounting and can be easily paired with thermal overload relays for total motor protection. Whether managing industrial pumps, ventilation systems, or automated production lines, the SC-4-1 delivers the precision and rugged reliability needed for critical infrastructure.
