Class 10A Manual / Automatic Overload Thermal Relay With AC Contactor

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 overload relays apply to circuit of AC 50Hz or 60Hz, rated voltage to below 660V and rated current . 1A-800A for AC motor overload and open-phase protection during long time or intermittent long time service, which can also protect 3-phase serious imbalance and long starting time of motor or long timer operation, can also be used for corresponding AC contactor for electromagnetic starter.

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

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
