Schneider Electric GV3 TeSys Series Auxiliary Contact

Are you looking to add an additional auxiliary contact to your control circuit, to provide further safety? Schneider Electric offers the latest in Auxiliary Contact components and technology.

Specifically, the GV3 TeSys series of Auxiliary Contactor brings reliability to your circuit by acting as a secondary switching device working in conjunction with other primary devices such as contactors, relays or circuit breakers.

Features and benefits:

• TeSys K range of Auxiliary Contacts is one of the smallest of the contactors add-ons in the market place making it suitable for use in tight spaces. The size, however, does not compromise on performance, with the range delivering peak efficiency and seamless integration with other applications.

• 100,000 cycles of mechanical durability can be expected with this product.

• Compact, lightweight and easily attached to compatible contactors. Front side mounting.

• Screw clamp terminals, flexible to fit certain types of cable (see datasheet for more information).

Protection ratings & Safety features:

• GB2CB06 circuit breaker <= 10 A protection type

• GG fuse <= 10 A

Applications:

• Noise sensitive areas.

• Programmable controller outputs.

• Other simple control systems.

How do Auxiliary Contacts work?

An Auxiliary Contact is an electromechanical device that is mounted typically to contactors. They are physically connected to the contactor, with simultaneous activation and deactivation applying to both of the devices at the same time.

Aux Contacts can be installed onto contactors either by front mounting, or side mounting. This is usually clear in the shape and size of the product, but please check the compatibility of your devices. Aux Contacts are really useful devices to aid in keeping an eye on the contactor.

You can, for example, hook up a low voltage LED directly to the Aux Contactor without having to worry about the overall voltage of the contactor it is linked to (as long the Aux Contactor is electrically isolated from the contactor) you could use the LED to monitor the device i.e. indicate if the motor is off/on.
