Interrupt Rating: Safely Interrupting Electrical Current – A GalcoTV Tech Tip


Welcome to Galco TV tech tips, your guide
to industrial electronics. Commonly found in circuit breakers and other protective equipment
is an interrupt rating that differs from the amperage rating or trip rating. The interrupt
rating is the breaking capacity that can safely interrupt the instantaneous current without
damage or an explosion that can damage the equipment and harm people in the area. This
instantaneous current can be caused by a short circuit or fault. When sizing a circuit breaker
to an electrical system, the amperage rating should be used, with only the interrupting
rating being a caution for how much current the unit can withstand before catastrophic
failure or destruction. To find out more about circuit breakers, check out our other videos
