Hoffman ATEMNOF Temperature Control Switch

Product Description

The HOFFMAN ATEMNOF is a fan temperature control switch designed to regulate cooling fan operation within electrical enclosures. This switch monitors internal enclosure temperature and activates or deactivates a fan based on thermal conditions, helping maintain safe operating temperatures for enclosed electrical and electronic components. Constructed of plastic in a light gray finish, it is sized at 2.36 inches by 1.30 inches by 1.62 inches. Electricians and panel technicians typically install this component during enclosure assembly or as a retrofit to improve thermal management in existing installations.

This temperature control switch is suited for use in industrial and commercial electrical enclosures where fan-based cooling is required. It is a standard fit for panel builders, industrial maintenance electricians, and automation technicians managing thermal conditions inside control panels, junction boxes, and similar enclosures. The open-contact (Open C) configuration makes it adaptable to a range of fan control wiring arrangements.

Installation Notes

Installation should be performed by a qualified electrician in accordance with applicable NEC requirements. De-energize the enclosure and verify the absence of voltage before beginning installation or wiring. Mount the switch securely to the enclosure panel per the manufacturer mounting instructions, and verify all wiring connections are tight and properly rated for the circuit. Do not apply power until installation is complete and the enclosure is properly closed.
