Mell What is the function of an auxiliary contact?
Basically, an auxiliary contactor is a regular (low-power) relay – but built like a “regular” contactor and when used together with another contactor it is called auxiliary contactor to clarify that it is not used for switching loads but has an activation/deactivation or control function instead – used to connect/ …
What two things do auxiliary contacts provide?
Auxiliary contacts are mainly used to signal switching or malfunction states, for interlocking circuits or logic and sequence controls with low to high loading. Many protection or control devices have additional auxiliary contacts.
What is electrical auxiliary contact?
Auxiliary contacts are secondary switching devices that work in conjunction with primary switching equipment such as circuit breakers, relays, and contactors. These contacts are physically linked to the main switching mechanism and activate at the same time it does.
How does an auxiliary relay work?
The auxiliary relay is the switch on the wall. Once the relay is opened by flipping the switch to turn the light on, a signal is sent to tell the light to turn on. When the relay is closed, or the light switch is turned in the opposite direction, a separate signal is sent to kill the power to the light.
How do I get rid of auxiliary contacts?
Grasp the contactor with your left hand. Put the thumb of your right on top of the aux contact and your first two fingers under the bottom of the aux contact. Using your thumb only, pull the top of the auxiliary contact slightly away from the contactor approximately .
What is the difference between auxiliary contacts and load contacts?
Auxiliary contacts are small and are intended to be used as part of the control circuit. Load contacts are large and designed to control a large amount of current.
What is the purpose of auxiliary relay?
An auxiliary relay is a relay that assists another relay or device in performing an action. It does this when its operating circuit is opened or closed. These relays are used in nearly all electronic devices to assist them in functioning correctly.
Why auxiliary relay is used?
Installation contactors and auxiliary relays are designed to switch more power (load) than the capacitance of the switching component. They are also used for so-called multiplication of contacts where more than one contact is needed. The auxiliary relays have quiet operation, LED signalling and switching contacts.
What is the function of auxiliary relay?
An auxiliary relay is a relay that assists another relay or device in performing an action. It does this when its operating circuit is opened or closed. These relays are used in nearly all electronic devices to assist them in functioning correctly. Essentially, it is as simple as an action done to…
What is an auxiliary contactor?
An auxiliary contactor is a regular (low-power) relay – but built like a “power” contactor and when used together with another contactor it is called auxiliary contactor.
What is an auxiliary contact block?
An auxiliary contact block is a piece of equipment that contains auxiliary contacts for a relay. A relay is a type of switch that is operated electronically, commonly with an electromagnet.
