What is contactor | Electric contactor | Ajmairy Electric StoreA contactor is an electrical manage switch,
used for switching an electrical electricity circuit. (1) A contactor is usually controlled by way of a circuit which has a much decrease power level than the switched circuit,
which includes a ( 24-volt coil electromagnet controlling A 230-Volt motor switch.
Unlike trendy-purpose relays, contactors are designed to be directly Connected to excessive-modern-day load devices.
Relays have a tendency to be of decrease ability and are generally designed for each normally closed and typically open packages.
Devices switching greater than 15 Amperes or in circuits rated a number kilowatts are commonly called contactors.
Apart from optionally available auxiliary low-present day contacts,
Contactors are nearly solely equipped with typically open
"shape A" Contacts. Unlike relays,
contactors are designed with functions to govern and suppress the arc produced when interrupting heavy motor currents.
Contactors are available many paperwork with various capacities and features. Unlike a circuit breaker, a contactor is not intended to break a quick circuit current. Contactors variety from the ones having a breaking current of several amperes to lots of amperes and (24) V DC to many kilovolts.
The physical size of contactors degrees from a tool small enough to pick up with one hand to massive devices approximately a meter at the aspect
