Circuit Breakers

T21-62-20.0A-01-31A-V Application Field and Working Principle

T21-62-20.0A-01-31A-V circuit breakers are one of the most reliable and effective components in electric devices and systems. They are essential in switching, isolating, and controlling electrical circuits. When the incoming current exceeds the rated current or a short circuit or overload occurs, these circuit breakers will shut it down to prevent electric shock or fire accidents.

The T21-62-20.0A-01-31A-V circuit breaker is used in low voltage applications and is designed for DC and AC currents between 0 and 20.0A. This type of circuit breaker is also equipped with thermal–magnetic protection and a snap action trip free mechanism for quickly detecting and tripping if either an overload or short circuit occurs.

The device is installed in electric panels, wiring boxes, control cabinets, etc. It is usually connected in series in a circuit breaker and can be directly mounted onto a standardized 35 mm DIN rail. The product is energy saving and has a long mechanical lifespan.

The working principle of the T21-62-20.0A-01-31A-V circuit breaker lies in its thermal-magnetic protection technology. This technology utilizes a heavy-duty electromagnet and a thermal element connected in parallel in each phase of the circuit breaker. The temperature sensitive component is used to detect when the incoming current is ecceeding the maximum rated level. When this occurs, the electrical connection between the load and power source is interrupted. This can eliminate the risk of an overload or short circuit.

The electromagnet is used to detect short circuits by measuring the amount of electric current passing through the circuit.When a short circuit occurs, a large amount of current is quickly generated which overloads the electromagnet. This activates a mechanism which causes the circuit breaker trip bar to quickly break the electrical connection.

Overall, the T21-62-20.0A-01-31A-V circuit breaker is a highly reliable and cost-effective component for protecting sensitive electric devices and systems against potential overloads or short circuits. Its working principle is based on thermal-magnetic protection technology which provides instant interruptions of electricity supply on detecting dangerous levels of power. The device can be easily used in several low voltage applications and provides long term reliability in safeguarding electrical systems.
