V7AM 100000 Time Life Cycles Electric Blanket Heating Metal Thermal Protector Bimetal Thermostat

Description of V7AM Bimetal Thermostat

V7AM is an excess-current thermal protector with compact design. The product has many advantages such as compact, big in contact capacity, sensitive in action, long life and so on.

Features of V7AM Thermostat

1. V7AM is relative compact designed and is operated with "Snap Action"

2. V7AM can reset automatically after tripping off.

3. Short circuit caused by contacting metal parts can be eliminated by leading wire with insulation sleeve 4. Length and leads type is optional.

Applications of V7AM Thermal Protector

The V7AM thermostat is a kind of over-temperature and over-current protector. It has small size, large contact capacity and quick tripping action. The main applications are as follows:
