Overload Relay

Thermal and Electronic Overload Relays

Overload relays mount directly on a contactor and trip it if the motor draws more than its rated current for too long. We stock thermal and electronic overloads from ABB, Chint, IMO, Lovato Electric and Emas, with the mounting links, remote-reset and label accessories to suit each contactor family.

Filter by current range and brand, and check the listing for the contactor series it fits. Related: contactors and manual motor starters, which combine both functions.
