Siemens Sirius 3RT1026 1A Siemens Sirius Contactor
Siemens Sirius 3RT1026 1A Siemens Sirius Contactor :
The Siemens Sirius 3RT1026 1A Siemens Sirius Contactor is a 3-phase IEC rated contactor used for the control of electric motors. It is rated 7.5 HP at 230V and 15 HP at 460V. Conforms to IEC 60946. Siemens 3RT1026 1A that is rated for 25 AMPS and 15 H.P. @ 460v Three phase and an AC rated coil (must specify voltage below). Comes with screw terminals and can be mounted on DIN rail.
In semiconductor testing, contactor can also refer to the specialized socket that connects the device under test.
In process industries, a contactor is a vessel where two streams interact, for example, air and liquid. See Gas-liquid contactor.
A contactor is an electrically-controlled switch used for switching an electrical power circuit. A 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. Relays tend to be of lower capacity and are usually designed for both normally closed and normally open applications. Devices switching more than 15 amperes or in circuits rated more than a few kilowatts are usually called contactors. Apart from optional auxiliary low-current contacts, contactors are almost exclusively fitted with normally open (“form A”) contacts. Unlike relays, contactors are designed with features to control and suppress the arc produced when interrupting heavy motor currents.
Contactors come in many forms with varying capacities and features. Unlike a circuit breaker, a contactor is not intended to interrupt a short circuit current. Contactors range from those having a breaking current of several amperes to thousands of amperes and 24 V DC to many kilovolts. The physical size of contactors ranges from a device small enough to pick up with one hand, to large devices approximately a meter (yard) on a side.
Contactors are used to control electric motors, lighting, heating, capacitor banks, thermal evaporators, and other electrical loads.
