Circuit Breakers

A circuit breaker is a device designed to protect electrical systems from damages caused by overloads, short circuits and other fault conditions. The 1658-G21-02-P10-6A circuit breaker is a multipole, thermal-magnetic, AC rated circuit breaker designed to protect properties from damages caused by overloads and short circuits. This circuit breaker is widely used in homes, panel boards, switchgears and control apparatus for safe operation of electrical distribution networks.

Application Field

The 1658-G21-02-P10-6A circuit breaker is particularly well-suited to residential, commercial and industrial applications where overcurrent protection is desired. This circuit breaker is commonly used in homes to protect properties from electric shocks and fire due to over-heating of wires. It is also used in industrial, commercial and residential panel boards to protect property and personnel. Due to its small size and low cost, it is also used in control apparatus and switchgears. Moreover, this circuit breaker is recommended for electric distribution networks where it provides easy installation, excellent reliability and good value for its cost.

Working Principle

The 1658-G21-02-P10-6A circuit breaker utilizes two components: a thermal-tripping mechanism and a magnetic-tripping mechanism. The thermal-tripping mechanism works by detecting an increase in the temperature of the wires due to an overload or short circuit. When the temperature reaches the preset point, the thermal-tripping mechanism triggers the circuit breaker to disconnect. The magnetic-tripping mechanism works by detecting an increase in current due to an overload or short circuit. When the current exceeds the preset point, the magnetic-tripping mechanism triggers the circuit breaker to disconnect.

The two mechanisms work together to ensure safe operation and protection of properties and personnel. When an overcurrent occurs, the thermal-tripping mechanism detects it quickly and triggers the circuit breaker to disconnect. At the same time, the magnetic-tripping mechanism is monitoring the current and detects any further increase and triggers the circuit breaker to disconnect. The two mechanisms ensure quick and safe disconnection of the circuit breaker and prevent any major damage to properties and personnel.

This circuit breaker is designed to give reliable protection against overcurrent. It complies with standards set by various organizations such as UL, CSA and CE and is suitable for use in residential and commercial applications. The 1658-G21-02-P10-6A circuit breaker has a small size and low cost, making it a good option for cost sensitive applications. It provides reliable operation and safety for the user.
