AC 3 Phase ls Thermal Overload Relay , 100A 125A Contactor Relay


Thermal overload relays are protective devices. They are designed to cut power if the motor draws too much current for an extended period of time. To accomplish this, thermal overload relays contain a normally closed

(NC) relay. When excessive current flows through the motor circuit, the relay opens due to increased motor

temperature, relay temperature, or sensed overload current, depending on the relay type.


These overload relays are similar to circuit breakers in construction and use, but most circuit breakers differ in

that they interrupt the circuit if overload occurs even for an instant. Thermal overload relays are conversely

designed to measure a motor's heating profile; therefore, overload must occur for an extended period before

the circuit is interrupted.


Applications:


UKH series thermal overload relay can be used in the circuit of 50Hz or 60Hz, rated insulation voltage 660V,

rated current 0.1-93A for protecting the phase break when the electric motor is overload. The relay has different mechanism and temperature compensation& can be plunged in UKC1 series AC contactor.
