How will a molded-case circuit breaker with a thermal trip unit react immediately after it has tripped, as a result of an overloaded motor circuit?
The breaker cannot be reset to the ON position until the thermal element cools down.
The breaker handle will lock in the OFF position.
The breaker handle will lock in the TRIPPED position.
The thermal element must be replaced after an overload trip has occurred before it can be restored into service.
