Thick copper wire Optional housing material Circuit breaker

The range of PG circuit breakers, from 5 to 60 A, (1 ph + N) or (3 Ph + N), with or without earth leakage protection (300mA-500 mA or 650mA), offers the product suitable for each type of installation.

Circuit breaker refers to the ability to close, carry and shut off current under normal circuit conditions and can close, carry and shut off current under abnormal circuit conditions within a specified time. Circuit breakers are divided into high voltage circuit breakers and low voltage circuit breakers according to their area of ​​use. The distinction between high and low voltage is rather vague. In general, those above 3 kV are called high voltage electrical devices.

Circuit breakers can be used to distribute electric power, rarely start asynchronous motors, protect power lines and motors, etc., and automatically shut off the circuit when they experience severe overload, short circuit and overload faults. under pressure. Its function is equivalent to a Combination switch fuse with overheating and overheating relay. In addition, it is generally not necessary to change parts after switching off the fault current.

Functioning principles

1. Service connections are the interface between the utility and the end user client;

2. They connect the customer's electrical installation to the electrical distribution network.

Benefits
■ Low cost product, suitable for conventional service connections.
■ Multiple classification system.
■ Several levels of sensitivity to earth leakage.

■ Complies with the French standard NFC 61450.

Security
■ Thermal compensation
■ The pole settings are not affected by the ambient temperature.
■ Residual current device
■ Highly reliable and self-powered system
■ Immune against overvoltages of atmospheric origin
■ Uninterrupted power supply for greater convenience.
■ Overvoltage prevention
■ The neutral pole is designed to close first and open last to maintain a fixed potential.
