Installation contactors and auxiliary relays are designed to switch more power load than the capacitance of the switching component. In electrical power wiring we use different types of relays and contactor motor starters and these have some contacts which we know with names of main contacts and coil contacts but this is not end we have also other contacts which we known with name of auxiliary contact.

How to wire contactors and auxiliaries.
Auxiliary contactor wiring. Some contactors provide an auxiliary output contact as a signal to the isolated part of the circuit that the contactor has been energized. How to wiring a power contactor and how install the auxiliary unit on it. Abbs contactor relays offering features products of technological advancement as well as products with specific purposes.
The electronically controlled coil offers multiple benefits over conventional alternatives and together with abbs wide product offering an optimal configuration every time. The auxiliary contact is often used in a relay logic circuit or for some other part of the motor control scheme typically switching 120 volt ac power instead of the motor voltage. One contactor may have several auxiliary contacts either normally open or normally closed if required.
Nf contactor relays allow use in all parts of the world and in all network conditions. This auxiliary contact will not be rated at the higher voltage. Check for an auxiliary output contact.
They are also used for so called multiplication of contacts where more than one contact is needed. Modules having auxiliary functions auxiliary contact modules having 2 or 4 contacts. Auxiliary contacts are used to provide memory to control circuits by being an additional motor starter.
How to wire contactor and motor protection switch direct. They are secondary switching devices which work in connection with primary switching devices such as relays contactors and circuit breakers. Contactor relays for auxiliary circuit switching.
The combination of no and nc contacts is according to en 50011. Buy the items featured in this video at 800 337 1720 or visit. The motor starter closes the auxiliary contact when energized causing a closed circuit.
These contacts are available in every contactor but these auxiliary. The auxiliary contact modules of the contactors dilem and dilm cannot be snapped onto the basic device to prevent duplication of terminal markings eg. Auxiliary relays and contactors.
How to wire up an auxiliary contact on a contactor presented by katie nyberg for galco tv. The auxiliary relays have quiet operation led signalling and switching contacts. Secure uptime and optimize stocks with af latest technology.
Nf contactor relays are featuring af technology as standard. Instead it should be rated at 120 volts ac.
