Auxiliary contacts, also known as auxiliary contactors are electromechanical devices used in conjunction with primary switching equipment such as contactors, circuit breakers, switches, and relays. These secondary switching devices are physically connected to the main switching equipment and work at the same time. The add-on accessories are available in a range of contact configurations and mounting styles to suit a wide range of industrial control applications.RS offer an extensive range of high-quality auxiliary contact blocks from industry-leading brands including Schneider Electric, Siemens, ABB, Lovato, Eaton, and of course RS Pro.

### How do auxiliary contacts work?

Auxiliary contacts are affixed to the main contacts and change state when the main contacts do. They pass the data from the circuit to a logic controller, which in turn gives instructions to the linked devices about whether to turn on or off. Alternatively, they can be used as a standalone hardware control unit. Auxiliary contacts are available in a variety of mounting styles such as a front mount or DIN rail mount and a range of terminal types including screw terminals, screw clamp terminals, and cage clamp terminals making it easy to find the right contact for the application.

### What are auxiliary contacts used for?

One common usage of auxiliary contacts is in push-button controllers, where they can be built into the start button. They are a common component in relay logic circuits solid-state electronics, electric motors, motor control schemes, and other industrial control applications.

### What are the different types of contact blocks?

There are two types of contact, contacts that are closed in a non-activated state and those that are open. They will be described as N/C (normally closed) and N/O (normally open).NC contacts are used as interlocks. NO contacts are used for switching on other components such as status indication lamps.



Auxiliary contacts are one of the conductive component parts of a contactor, which is a type of electrically controlled switch that forms part of a circuit.

ABB auxiliary contacts are electromechanical devices that can be used in conjunction with switching equipment, such as circuit breakers and contactors. In partnership with RS, ABB bring to you a comprehensive, high-quality, and reliable range of auxiliary contacts. The range encompasses a variety of auxiliary contacts that act as secondary switching devices. They can be physically connected to the primary switching device to work at the same time and control the main device to connect and disconnect a circuit. So if you want to enhance the operation, safety, and control of your electrical systems, choose ABB auxiliary contacts.<h2>How do ABB auxiliary contacts work?</h2>ABB auxiliary contacts, also known as auxiliary contactors, work by controlling another (usually larger) switch. The auxiliary contact is constructed with a coil that has high-power contacts inside and low current contacts on either end. An auxiliary contactor is constructed like a standard contactor, but rather than switching loads, it has a control function that can activate or deactivate a circuit. They are often used in conjunction with load contactors, that act as the main contact. Load contactors can generally handle loads of around 600 A, whereas auxiliary contactors are lower power relays and can be installed to control the main device, i.e., the load contactor.<h2>Applications</h2>ABB auxiliary contacts can be used across a variety of fields for numerous purposes. Some key applications include: <ul><li> Remote monitoring and control in automated systems</li><li> Circuit breaker control</li><li> Alarm systems</li><li> Safety circuits</li><li> Electrical maintenance</li><li> Energy management systems</li></ul>
