1B40UR

The 1B40UR is a type of circuit breaker, which is used to protect an electrical circuit from short-circuiting or overloads. The 1B40UR circuit breaker is a standard breaker and has voltage ratings up to 600 volts and current ratings up to 30 amps. It is UL listed and CSA certified.

The 1B40UR is typically used in residential and commercial applications, but can also be used for industrial applications. It is versatile and can be used for small, medium and large projects. The 1B40UR is designed to protect circuits from damage due to overloads, short circuits, and other failures.

The 1B40UR operates on the vacuum principle, meaning that the breaker trips when its internal vacuum switch senses the presence of an abnormal current or an abnormal voltage. When this happens, the vacuum switch breaks the circuit and the breaker trips. The breaker will remain tripped until the abnormal condition is corrected and the reset is pushed.

In addition to providing protection against overloads and short circuits, the 1B40UR also has self-testing capabilities. It is designed to test itself periodically to ensure that it is in proper working order. This self-testing helps reduce the risk of equipment failure, reducing the need for costly repairs and downtime.

The 1B40UR is a reliable and effective circuit breaker that can provide protection for a variety of applications. It is a great choice for residential, commercial and industrial applications, providing critical protection against circuit failure or overload. The self-testing capabilities also provide added assurance that it is working properly.
