Square D CC50.1 Contactor Thermal Unit C Series

Product Description

The SQUARE D CC50.1 is a thermal unit accessory designed for use with C Series contactors. Thermal units provide overload protection by sensing heat generated from current flow through the circuit. When excessive current causes the thermal element to trip, the contactor opens the load circuit to protect connected motors and equipment from damage. This component is installed by licensed electricians and industrial maintenance technicians working on motor control centers, panel boards, and contactor assemblies in commercial and industrial applications.

This thermal unit is intended for use in motor control and load-switching applications where overload protection is required. It fits into C Series contactor assemblies and serves as a replacement or spare component during routine maintenance or field repairs. Its compact size makes it suitable for panel installations where space is limited.

Installation Notes

Installation should be performed by a qualified electrician in accordance with applicable NEC requirements. De-energize and lock out the panel or motor control center before removing or installing thermal units. Verify that the replacement thermal unit matches the required trip class and current rating for the protected load before placing the assembly back in service.
