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.

Tesys D side mount auxiliary contacts (662-6248, 744-6983, 400-1467, 400-1473) are not compatible with Tesys D DC Contactors.

This auxiliary contact block is designed for use in various industrial applications, specifically within the TeSys range. The contact block features a configuration of 2 normally closed and 2 normally open contacts, tailored for optimal performance. Its compact dimensions of 48mm height, 44mm width, and 42mm depth make it suitable for front mounting in tight spaces. The unit is equipped with screw clamp terminals, which ensure a reliable connection and ease of wiring in automation systems.

• Front mounting simplifies installation in compact environments
• 2NC and 2NO configuration enhances circuit control versatility
• Screw clamp terminal block allows for secure cable connections
• Designed for a wide operating temperature range of -5°C to 60°C
• Green Premium contact block supports environmental standards
