Circuit Breakers

Circuit breakers, also known as a trip switch, are a safety feature installed in electrical circuits when a circuit is overloaded or short circuited, a simple device is activated to automatically turn off the electricity supply. The UPGN662-25546-1 circuitbreaker is top-of-the-line, designed for the most demanding industrial applications and designed to be reliable, safe and easy to install & maintain.

UPGN662-25546-1 application field and working principle

The UPGN662-25546-1 is a high voltage circuit breaker specifically designed to provide reliable protection and safe operation for mobile and portable electrical cords and equipment in the event of short circuit. This circuit breaker has a rated working voltage of 400-690V and a maximum operating voltage of 820V, with a rated current up to 125A. Its applications range from high voltage distribution networks to machine and equipment control systems.

The UPGN662-25546-1 circuit breaker consists of two main parts: the trip switch and the trip lever. The trip switch is a semi-conductor-based device that monitors the circuit for overloads and short circuits. When an overload or short circuit is detected, the trip switch triggers the trip lever, which physically switches off the circuit.

In the event of an overload or short circuit, the thermal trip switch quickly opens the circuit to interrupt the current flow. As soon as the current flow is interrupted, the magnetic trip switch is activated, which further decreases the current flow and eventually brings it to zero. The combination of these two actions prevents any further increase in current and therefore avoids any further damage to the equipment or electrical wiring.

The UPGN662-25546-1 is an advanced circuit breaker, with a dual protection system for extra safety. It also features an integrated auto-reset function, which automatically turns the power back on when the circuit is restored to a normal state. This makes it an ideal choice for use in electrical installations where safety and reliability are a top priority.

UPGN662-25546-1 circuit breaker is easy to use and maintain. Thanks to its compact design, it can be fitted easily in most types of electrical panels. Moreover, its robust construction makes it highly reliable and long-lasting. All in all, the UPGN662-25546-1 is an ideal choice for reliable circuit protection in high voltage electrical systems.
