T51-4-20.0A-01-11L

Circuit Breakers

A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. Its basic function is to detect a fault condition and, by interrupting continuity, to immediately discontinue electrical flow. This action, whether accomplished by opening and closing contacts, removing fuses, or tripping relays, results in an "open" circuit and minimizes the likelihood of seriousDamage due to excessive current.The T51-4-20.0A-01-11L is a low voltage air circuit breaker (ACB) designed for motor control and protection applications. This product is compliant with the requirements of IEC 60898-1 for residential and similar installations. It is designed for use as an overcurrent protection device for short circuit and overload protection for AC motors.

Features and Benefits

This ACB combines a number of features that offer superior performance from an overall cost standpoint. It features a built-in shunt trip, two pole switching and torque-limiting releasing action. Other features include a DC tolerance of +/- 5%, adjustable trip curves to provide the proper current trip level and no required current setting.

Application Field and Working Principle

The T51-4-20.0A-01-11L is designed for residential, commercial, and industrial applications. It can be used as a main switch, motor control, and breaker in applications ranging from lighting systems, air-conditioning systems, pumps, motors, and heating systems.The working principle of the circuit breaker is fairly simple. In its most basic form, it consists of a switch which is held closed by a spring. When an overload current is detected, the switch will trip and open due to the force of the overload current. This action breaks the circuit, protecting it from the current. Additionally, the circuit breaker can be manually opened and closed when needed.

Advantages

The T51-4-20.0A-01-11L circuit breaker offers several advantages over traditional circuit breakers, including:- Increased safety due to the torque-limiting release action- Lower overall costs due to the adjustable trip curve and no required current setting- Improved reliability due to the DC tolerance of +/- 5%.

Conclusion

The T51-4-20.0A-01-11L is an ideal circuit breaker for residential, commercial, and industrial applications. It offers superior performance, increased safety and improved reliability, all at a cost-effective price. With its adjustable trip curves to provide the proper current trip level and torque-limiting releasing action, it provides the best of both worlds in terms of reliability and affordability.
