Circuit Breakers

Circuit breakers are essential components to prevent overcurrent in electrical systems. This includes preventing short-circuiting, overloads, and accidental current disconnection. The 1658-G21-02-P10-055800-8A circuit breaker is a product designed to address these issues in many applications. This article will discuss the circuit breaker’s application field and working principle.

Application Field

The 1658-G21-02-P10-055800-8A circuit breaker is designed for use in a range of applications. It is suitable for motor starter overload protection and lighting overload protection. It can be used in a variety of risky environments including kitchens, shipyards, and workshops.

This circuit breaker has a wide operating temperature range from -15°C to +60°C. It is able to withstand sudden short circuit currents and is capable of transmitting up to 70kA of short circuit current. The rated working voltage of this circuit breaker is 400V and operates in frequencies of 50Hz and 60Hz. Its design enables it to be used for low and high powers systems, which is attractive for applications requiring multiple power levels.

Working Principle

The 1658-G21-02-P10-055800-8A circuit breaker works by using a thermal-magnetic tripping system. When there is an overcurrent, it trips the breaker in a matter of milliseconds, thereby protecting any wiring and connected appliances from a potential fire or explosion. In addition to protecting against overcurrent, this circuit breaker also monitors temperature, voltage imbalances, and ground-faults.

In terms of the mechanism of the thermal-magnetic tripping system, it utilizes three main components: the thermal element, the electromagnetic element, and the dual-pole actuation. The thermal element is the main tripping element which will be activated by an excessive amount of current over a set period of time. The electromagnetic element provides a fast response for short circuit protection. And the dual-pole actuation is responsible for releasing the latching mechanism and tripping the breaker.

The 1658-G21-02-P10-055800-8A circuit breaker is able to monitor abnormal voltage levels and trigger an alarm when the voltage exceeds the operating limits. Thus, it offers increased safety and helps in mitigating the risk of fire hazard for protected equipment.

Conclusion

The 1658-G21-02-P10-055800-8A circuit breaker is an excellent device that offers various features to effectively reduce the risk of overcurrent and ensuing fire or explosion. It has a broad application field and can be used in many environments. The circuit breaker runs on a thermal-magnetic tripping system and is able to monitor and trip the circuit breaker whenever there is an overcurrent, short-circuit, or voltage overload. It is an indispensable safety device for many applications and should be taken seriously.
