General Electric TJK436Y400 Disconnect Switch

The General Electric TJK436Y400 is a non-fused safety disconnect switch built for reliable isolation in industrial electrical distribution networks. Engineered with a continuous current rating of 400 amperes and a maximum voltage of 600 volts, this unit provides a secure manual break point for servicing high-power circuits. It integrates three auxiliary switches to transmit contactor status back to control interfaces, facilitating remote monitoring of the system condition. Furthermore, the included 48-volt shunt coil enables automatic tripping actions triggered by external signals such as fire alarms or overload relays.

This configuration serves critical functions in factory floors or commercial buildings where both manual lockout/tagout safety and automated shutdown response are mandatory. The auxiliary contacts allow operators to verify isolation without physically accessing the main enclosure, reducing labor exposure risks. Its design fits standard NEMA-compatible enclosures, ensuring straightforward installation alongside existing switchgear infrastructure.
