Typically I've always understood that a specific motor circuit breaker was to be used in combination with a motor starter. When I say motor circuit breaker I am refering to an magnetic instantaneously only circuit breaker that is to only provide short circuit protection in combination with the motor overloads providing overload protection.
My question is weather or not a thermal-magnetic breaker can be used as the circuit breaker or means of short circuit protection in a motor starter. We want to get a motor back up and running and do not have an exact motor breaker as a replacement but do have a thermal-magnetic breaker avaliable. Can this type of breaker be used?
Also in looking through the Siemens catalog I notice there are tons of different Molded Case breaker types. Many of these breakers are labeled as General Purpose Breakers. What is it that distinguishes one of these type of breakers from another?
In other words what distinguishes a HED4 from a HFD6 from a HLD6 from a JDX6 ect....???
