GTH-12M Mini Motor Thermal Overload Relay , Overload Protection 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.

 

 

Characteristics:


1. Be mounted with contactor UKC(D)1-6M/9M/12M directly 


3. Small size: 44mm width 


4. 1NO+1NC tripping contact 


5. Class 10A tripping standard 


6. Phase-failure protection type: UKK 


7. Sstandard type: UKH 


8. Applicable ambient temperature: -5 to 40 degree 


9. Manual/automatic reset 


10 Ewmote reset is optional 


11. Design of free trip

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.
