Circuit Breakers

Circuit breakers protect electrical circuits from damage due to shorts or overloads. When an abnormally high current passes through a circuit, the electric current causes a checking switch linked to the circuit to open, causing a break in the circuit, cutting off the current and preventing damage. In many cases, circuit breakers can be reset and circuit operation continues.

UPG211-2REC4-4949-4 Application Field and Working Principle

The UPG211-2REC4-4949-4 is a miniature circuit breaker (MCB) used in residential, commercial, industrial and general purpose applications. The UPG211-2REC4-4949-4 MCB is rated amongst the highest in the industry that suits the specific application needs for safety and reliability.

Firstly, the device is designed to protect short-circuit and overload conditions in branch circuits. It is suitable for use as a branch protection device in combination assemblies, such as meter board assemblies, contactor assemblies, and manual-auto selector assemblies. Secondly, it is suitable for use in protection assemblies for electric motor circuits.

The UPG211-2REC4-4949-4 is also designed to provide protection against electrical shocks for personnel in locations outside the direct hazardous area — but not indoors. It also offers reverse current protection, which can be used to ensure that any non-permanent connections are not crossed. When it comes to everyday electrical use, users also have the possibility of switching between single pole and double pole mode for protection against uncertain and potentially dangerous voltage variations.

The UPG211-2REC4-4949-4 circuit breaker has a tripping mechanism allowing current-sensing elements and a thermal memory. The current-sensing trip function provides instantaneous protection against the short-circuit and overload in the event of a trip. The thermal memory ensures that each re-trip will provide protection during the same resistance-to-fault event.

The UPG211-2REC4-4949-4 has a self-locking mechanism that ensures the device is safe to use at the rated current. To unlock the circuit breaker, a simple button press is all that is needed to reset the circuit breaker.

In summary, the UPG211-2REC4-4949-4 circuit breaker is designed to protect circuits and personnel against potential danger from electrical malfunctions. It is a reliable and robust device that provides snap action on short-circuit and overload conditions, with reliable trip time and accurate tripping characteristics.
