Motor Thermal Overload Protection Electrical4U

WebA thermal overload relay, commonly called a ‘thermal overload’, is a device which is usually connected directly to a motor contactor. It offers overload protection only, so must be coupled with an upstream magnetic circuit breaker for short circuit protection. Thermal overloads are generally cost-effective, reliable and simple to install ... WebOct 21, 2024 · Thermal overload relays are typically part of the motor starter, which includes the overload relay plus contacts. It’s important to note that thermal overload relays are only designed to protect the motor from overheating, and won’t trip if there’s a short circuit, so additional fuses or circuit breakers are necessary to protect the circuit.
