Safety Phase Failure Protection Industrial Relays , Easy Operation
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.
This product has innovative, elegant model and small installation area, functions such as temperature compensation, action indication, automatic and manual reset / stop with steady and reliable performance.
Thermal relay can be combined / connected with contactor or installed separately.
Standard: IEC 60947-1
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.

Features:
1. Direct mounting structure:
The thermal overload rela can be mounted directly to the Magnetic Contactors without
additonal brackets. (Applied model: UKH-22, 40, 85,100,150,220,630)
2. Safety cover
The finger proof safety cover prevent careless touch of electric conductor
3 . Separation of power part and operation part
The main circuit and the operation part are separately designed and the operation part is commonly used.
4 . Easy operation
