Circuit Breakers

A circuit breaker is a device designed to protect electrical circuits from damage caused by overload or short circuit. Circuit breakers are an essential component of any electrical safety system. The LELPK11-33378-1-V is an example of a circuit breaker.

Application Field

This circuit breaker is designed for use in low-voltage applications of up to 100V AC. It can be used in a variety of industries such as construction, oil and gas, and manufacturing, where safety and reliability are of utmost importance. It is also suitable for residential applications, for example in homes, garages, and apartments. It can be used as a main disconnect switch, overload protection device, and short-circuit protection device.

Working Principle

The LELPK11-33378-1-V circuit breaker is designed to open when the circuit current reaches a predetermined level, thus protecting the circuit from overcurrent or short circuit. It has a thermal-magnetic trip curve, meaning that it uses both temperature and magnetic principles to detect overcurrent and short circuit conditions. When a high current is detected, the thermal component of the breaker detects the heat generated by the current, and trips the breaker when the temperature reaches a certain level. Meanwhile, the magnetic component senses the increase in current, and trips the breaker if the current exceeds a certain pre-set limit. In either case, the breaker will open, interrupting current and protecting the circuit.

Conclusion

The LELPK11-33378-1-V circuit breaker is a reliable and efficient overload and short circuit protection device. It is designed for use in low-voltage applications of up to 100V AC, and is suitable for a range of industries and residential applications. It is designed to open when the circuit current reaches a predetermined level, using both thermal and magnetic principles to detect overcurrent and short circuit conditions, thus protecting the circuit from damage.
