Measurement of Contactor coil resistance using Rish Con TPT

Overview In electrical systems and various industrial applications, contactors are used to remotely switch electrical power. The coil-actuated switch operates exactly like a relay, but a contactor typically handles higher amperes in the switch mechanism itself. The contactor coils are designed to be able to cope with continuous duty. Typically the contacts, two each to …
