Circuit breakers are devices used to protect a circuit from electrical overload or short-circuit. They are essential components of all electrical systems, from the small two-wire home wiring systems to the largest industrial systems, to prevent damage to electrical equipment and minimize the risk of fire, shock and electrocution. The T10-S-SW-01-10A is a type of circuit breaker designed specifically for sensitive overload protection applications. Its distinguishing feature is its ability to differentiate between true fault current and inrush current, preventing false tripping during power up and allowing greater latitude in the selection of circuit breakers. This article will discuss the application field and working principle of the T10-S-SW-01-10A circuit breaker.

Application Field

The T10-S-SW-01-10A circuit breaker is typically used in medium-voltage applications as a sensitive overload protection device in power distribution systems. It can be applied to protect a range of electrical equipment, including motors, transformers, generators, and switchgear. The breaker has a wide range of trip setpoints and can protect against short-circuit currents (7I⁄2 to 18 times its nominal current rating) and overload currents (2 to 8 times the nominal current rating). The breaker has a temperature compensation feature that adjusts the system\'s trip setpoint as equipment expands and contracts. This ensures that delicate components are not damaged unnecessarily when temperatures rise.

Working Principle

The working principle of the T10-S-SW-01-10A circuit breaker is based on a bimetal disc mechanism which is used to detect the rise in current due to an overload or short-circuit. When an overload occurs, the bimetal disc heats up and bends, which opens the circuit breaker and disrupts the current. The breaker also has an adjustable trip setpoint, allowing it to be tuned to the needs of the application. The T10-S-SW-01-10A has a reset button which must be manually pressed to restart the breaker once it has tripped. The reset button is a safety feature which eliminates the possibility of the breaker automatically restarting after a trip.

Conclusion

The T10-S-SW-01-10A circuit breaker is a sensitive overload protection device designed for medium-voltage applications. It is based on a bimetal disc mechanism and has an adjustable trip setpoint. The breaker is capable of detecting both overloads and short-circuits and has a temperature compensation feature to prevent damage to electrical equipment. It is a reliable and cost-effective solution for protecting electrical systems from damage and minimising the risk of fire, shock, and electrocution.
