The new SEQUESTR™ External Disconnect Enclosure from Hoffman is designed to isolate the fused disconnect switch or circuit breaker from the main control panel while maintaining the door interlocking requirements of the principal electrical standards for industrial machinery.
By isolating the switch, live power is no longer present in the main control enclosure when power is turned off at the switch. This allows technicians to work inside the main enclosure without needing to wear personal protective equipment. When main power is on at the disconnect, SEQUESTR’s own door cannot be opened, and its interlock prevents the main enclosure door from being opened. Expected to be available in 4th quarter as a complete package for OEMs and as a retrofit kit for upgrading existing installations.
