Circuit breakers are essential components used in electrical systems to provide overload and short circuit protection. They are designed to detect faults, protect equipment and prevent fires. A T21-2-25.0A-01-31AL is a thermal-magnetic circuit breaker with a current rating of 25.0 amps and a voltage rating of 400V AC. This circuit breaker is used in various applications to ensure safe operation and protect against over-currents and short-circuits.

Application Field

The T21-2-25.0A-01-31AL circuit breaker is designed for use in domestic and commercial applications, particularly in the following:

• Appliance circuits
• Lighting circuits
• Power circuits
• Machinery and equipment installation
• Multi-story buildings

Due to its versatility and reliability, the T21-2-25.0A-01-31AL circuit breaker is used in various applications including kitchens, bathrooms, offices, workshops, factories and other areas where basic electrical protection is required.

Working Principle

The T21-2-25.0A-01-31AL circuit breaker combines thermal and magnetic principles of operation. The thermal element operates when the current is high, by detecting the heat generated by the excessive current flowing through the circuit and causing it to trip. The magnetic element is used as an over-current protection, as it will trip the circuit when the current exceeds the set rating.

The internal components of the T21-2-25.0A-01-31AL circuit breaker include a trip column, a thermal overload relay, a contact arm and a shield. When the circuit is operating normally, the contact arm remains closed and the shield is in the open position. When an overcurrent or short circuit occurs, the thermal element will detect the heat generated and trip the circuit. The trip column will then move the contact arm and shield, which will open the circuit, therebybreaking the flow of current.

The T21-2-25.0A-01-31AL circuit breaker also has a manual reset button for easy resetting in case of an emergency. This feature makes it a reliable and convenient way to reset a circuit.

Conclusion

The T21-2-25.0A-01-31AL circuit breaker is a reliable and versatile product with a current rating of 25.0 amps and a voltage rating of 400V AC. It is designed for use in domestic and commercial applications to protect against over-currents and short-circuits. It combines thermal and magnetic principles of operation and features a manual reset button for easy resetting in case of an emergency. The T21-2-25.0A-01-31AL is a cost-effective solution for ensuring safe, reliable and efficient operation of electrical systems.
