Circuit Breakers

A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. Its basic function is to interrupt current flow after a fault is detected. Unlike a fuse, which operates once and then must be replaced, a circuit breaker can be reset (either manually or automatically) to resume normal operation.

BA2-B0-34-630-221-D circuit breaker

The BA2-B0-34-630-221-D is an AC circuit breaker specifically designed to protect life, property and equipment from electrical hazards. It is suitable for single or three-phase AC systems up to 208V and can be used in a variety of residential, commercial and industrial settings. The breaker utilizes thermal-magnetic technology to provide fast and accurate protection from short-circuiting, over-current and ground fault events. The maximum number of poles allowed is 3.

Application Fields of the BA2-B0-34-630-221-D

It can be used in a variety of applications, including panelboards, industrial machinery and equipment, switchboards and motor control centers. It can also be used to protect a variety of appliances, such as air conditioners, refrigerators, washing machines, pumps, heating elements and more.

Working Principle of the BA2-B0-34-630-221-D

The BA2-B0-34-630-221-D circuit breaker utilizes a combination of thermal and magnetic technology to provide accurate protection from short-circuiting and over-current events. The breaker contains a bimetallic strip which is heated when an over-current flows through the breaker. The heat causes the strip to expand which, in turn, causes a lever to move and release the tripping mechanism. The magnetic portion of the breaker works similarly, but instead of expanding, the magnetic forces create an opening in the breaker which trips the mechanism. The breaker is designed to reset itself after the fault has been cleared, allowing the circuit to be restored.

In addition to providing protection from over-current and short-circuiting, the BA2-B0-34-630-221-D circuit breaker also provides protection against ground fault events. This is done through the use of a ground fault protection module which monitors current in the neutral conductor. If an imbalance is detected, the module will trip the breaker, protecting life and property.
