All product photos and testing videos below are original materials captured first-hand by the Koeed technical team in our warehouse prior to dispatch.

The Fuji Electric SC-N1 220V AC magnetic contactor is a 50A-rated IEC and UL certified motor control device built for industrial panels, HVAC, pumps, conveyors, and compressor starters. It uses a 220V AC coil and provides durable switching with auxiliary contact options.Key specifications include rated operational current 50A, coil voltage 220V AC 50/60Hz, main poles 3, auxiliary contacts 1NO+1NC or configurable, mechanical life up to 10 million operations, electrical life around 1 million operations at rated load, and operating temperature range -5 to +55 degrees C.For 2026 engineering and predictive maintenance, pair the SC-N1 with current transducers, thermal overload relays, and IIoT monitoring modules to track contact wear, coil temperature, and switching counts. This supports condition-based service, reduces unplanned downtime, and extends panel life.When replacing legacy contactors, verify coil voltage, SCCR, and UL/IEC ratings. The SC-N1 series remains a dependable, cost-effective choice for OEMs and panel builders needing a compact 220V AC contactor with proven service life.
