Gas station network protection circuit breaker
Automatic circuit breaker for the gas station series & nbsp; is intended for automatic shutdown of electricity consumers in case of overloads and short circuits in DC circuits at voltages up to 30 V in closed stationary and mobile installations. Circuit breakers are classified by their rated current.
Gas station symbol structure - [*] [*]:
 Gas station - automatic network protection; 
 [*] [*] - value of rated current, А (2, 5, 10, 15, 20, 25, 30, 40, 50). 
Design Features
Circuit breakers are a combination of a single-pole circuit breaker and a thermo-bimetallic element that provides automatic shutdown of the protected object. The machines have a mechanism without a free release. Plus is brought to a fixed contact.
