Custom AC Bimental Magnetic Thermal Overload Contactor Relay GTH-85

Custom AC Bimental Magnetic Thermal Overload Contactor Relay GTH-85

Bimetallic thermal overload relays use a bimetallic strip to mechanically open the contacts. Bimetallic strips consist of two conjoined pieces of metal which expand at different rates when exposed to heat.

This difference forces the strip to bend when heated. In a thermal relay, the strip is attached by a spring to a contact. When excess heat from overcurrent causes the strip to bend and pull the spring, the contacts are pulled apart and the circuit is broken. When the strip is cooled it then returns to its original shape.

Specifications:

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.

It is used for overload protection and has the function of breaking phase protection, temperature compensation and trip indication. It can automatically and passively get back. It can be fixed with contactor together, also be independently fixed.

Wiring:

Working condition:

1. The installation altitude less than 2000m

2. The surrounding temperature range: from -5°C ~ +40°C

3. In the non-explosive condition. or without adequate erosion and destruction of gas

and dust conductive area .

4. Without rain and snow invade

5. Pollution level 2
