WebA circuit breakerATS has a longer and unpredictable transfer timedue to the fact that two drive mechanisms need to be triggered independently and sequen-tially. Assuming two … WebA contactor is typically controlled by a circuit which has a much lower power level than the switched circuit, such as a 24-volt coil electromagnet controlling a 230-volt motor switch. Unlike general-purpose relays, contactors are designed to be directly connected to high-current load devices.
