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.

• 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

• Noise sensitive areas.

• Programmable controller outputs.

• Other simple control systems.

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.

For a simple way to dial up control circuit safety to the maximum, choose this auxiliary contact from Schneider Electric. It attaches to the side of your contactor, relay or circuit breaker and acts as a secondary switching device. This slim unit slots easily into smaller spaces, with dimensions of just 89 (H) x 9.3 (W) x 66mm (D). It's lightweight too, at just 55g, putting minimal strain on your setup. Despite its compact size, the contact packs a punch, with 240V DC and 690V AC voltage ratings making it suitable for high-energy installations.

• Lasts for the long term thanks to mechanical durability of 100,000 cycles
• Screw-clamp terminals make it easy to wire and achieve a secure connection
• 2NO configuration means it can handle two circuits

• Mechanical workshops
• Automated control systems
• Computer engineering

The tightening torque of this unit is 1.4Nm on the screw-clamp terminals. When the connections are suitably tightened, you get a secure installation that stands up to mechanical vibrations.
