Circuit breakers, or CBs, are an integral part of any power system. Circuit breakers provide protection for electrical equipment from overcurrent, overload and short circuit conditions. The 219-1-1-65-3-7-15 circuit breaker is a single-pole thermal-magnetic circuit breaker designed for protection of single-phase circuits. It is designed for indoor use in domestic or light industrial applications.

Application Field

The 219-1-1-65-3-7-15 circuit breaker is primarily used in domestic, commercial, and light industrial applications. It is rated for a voltage of 230 V a.c. and is available in four different amp ratings: 10A, 16A, 20A and 32A. It can be used to provide overload and short circuit protection in single-phase circuits up to 32 amps. It is also suitable for protection of distribution boards, switch boards, lighting systems, power outlet outlets, and similar applications.

Working Principle

The 219-1-1-65-3-7-15 is a thermal-magnetic circuit breaker. It has two operating modes: thermal and magnetic. In the thermal mode, the current is monitored and the circuit breaker will trip if the current exceeds a predetermined level. In the magnetic mode, an external magnetic field is used to trip the circuit breaker. The external magnetic field can be from a fuse or an earth leakage protection device, for example.

The thermal-magnetic principle of operation provides an added layer of protection. The thermal mechanism keeps the breaker off until a predetermined current is exceeded. This helps protect the electrical system from overload conditions. The magnetic mechanism instantly trips the breaker when the external magnetic field is exceeded. This helps to protect the system from short circuits and other dangerous conditions.

The 219-1-1-65-3-7-15 circuit breaker is equipped with a manual release button. This allows the user to reset the breaker after it has been tripped. The breaker also includes a visual indicator which shows whether the breaker is in the on or off position. This helps the user to quickly identify whether the breaker is tripped or not.

Conclusion

The 219-1-1-65-3-7-15 circuit breaker is an economical and reliable single-pole thermal-magnetic circuit breaker designed for protection of single-phase circuits in domestic, commercial and light industrial applications. It is equipped with a manual release button, which allows the user to reset the breaker after it has been tripped, and a visual indicator which shows the on or off position. The thermal-magnetic principle of operation provides an added layer of protection, allowing the breaker to provide protection against overload and short circuit conditions.
