The new SEQUESTR™ External Disconnect Enclosure from Hoffman is designed to isolate the fused disconnect switch from the main control panel while maintaining the door interlocking requirements.
By isolating the switch, live power is no longer present in the main control enclosure. Technicians can work inside the main enclosure without protective equipment. When main power is on at the disconnect, SEQUESTR’s door cannot be opened, and its interlock prevents the main enclosure door from being opened. Expected to be available in 4th quarter.
