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.

Specifications:

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
