Motor circuit breaker 3P 0.63-1A PKZM0-1-EA Eaton

Product description

Any long and demanding work with an electric motor has a high probability of overload or short circuit. The only way with such high efficiency is to use a motor circuit breaker. This is a device designed for protection. The main task is to prevent the occurrence of possible damage to the electric motor. The device will also protect the electrical mechanism if a phase loss occurs. The motor circuit breaker should be well matched to the power of the device in question. We suggest you contact a qualified electrician or the manufacturer of the equipment in question to get the most certain information. This will provide you with a lot of time and unnecessary nerves when trying to fit the right switch.

The motorized switch ensures uninterrupted operation of the equipment even for several hours. Most often, this product finds its use in the manual switching off and on of a protected motor. This is because it is the fastest almost instantaneous process of switching off the equipment. Installing a motor switch k is an important protective function and will protect the equipment in case the motor current obtains undesirable parameters. It is also advisable to use it in work on equipment where there are adverse weather conditions or the machine requires more power to operate. We assume that an electrical overload occurs when there is an increased current voltage (higher than the rated current) in the circuit of the electrical system. The thermal trip that is part of the motor circuit breaker reacts almost immediately when an overload is detected and protects the motor windings that could overheat.
