How to wire contactor and motor protection switch direct.
Auxiliary contactor wiring. Nf contactor relays are featuring af technology as standard. How to wire contactors and auxiliaries. 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.
They are also used for so called multiplication of contacts where more than one contact is needed. Auxiliary relays and contactors. One contactor may have several auxiliary contacts either normally open or normally closed if required.
Modules having auxiliary functions auxiliary contact modules having 2 or 4 contacts. Secure uptime and optimize stocks with af latest technology. This auxiliary contact will not be rated at the higher voltage.
Contactor relays for auxiliary circuit switching. Instead it should be rated at 120 volts ac. The auxiliary contact modules of the contactors dilem and dilm cannot be snapped onto the basic device to prevent duplication of terminal markings eg.
How to wiring a power contactor and how install the auxiliary unit on it. Check for an auxiliary output contact. Abbs contactor relays offering features products of technological advancement as well as products with specific purposes.
They are secondary switching devices which work in connection with primary switching devices such as relays contactors and circuit breakers. Some contactors provide an auxiliary output contact as a signal to the isolated part of the circuit that the contactor has been energized. The auxiliary relays have quiet operation led signalling and switching contacts.
Nf contactor relays allow use in all parts of the world and in all network conditions. 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 up an auxiliary contact on a contactor presented by katie nyberg for galco tv.
The combination of no and nc contacts is according to en 50011. Auxiliary contacts are used to provide memory to control circuits by being an additional motor starter. Installation contactors and auxiliary relays are designed to switch more power load than the capacitance of the switching component.
