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 LADN 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.

• Low consumption on your control circuit
• 30 Mcycles of mechanical durability
• Compact, lightweight and easily attached to compatible contactors. Front side mounting
• Simplified mounting directly to the contactor/circuit breaker. Compact in size and equipped with EverLink terminal technology meaning permanent tightening even in the event with conductor creep
• 18-month manufacturer warranty with Schneider

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.

Are you looking for a way to rev up your control circuit safety? This auxiliary contact block from Schneider Electric adds a secondary layer of protection to your system. Working together with your usual circuit breakers or contactors, it switches off overloaded devices in a flash. This hardworking little device stands up to heavy use, with 30 M-cycles of mechanical durability. Clip-on front mounting takes the guesswork out of installation – just attach the block directly to your control relay or contactor.

• Screw clamp terminals ensure a tight and secure fit
• EverLink technology keeps it in place, even with conductor creep over time
• Boosts efficiency by helping prevent energy-consuming power overload
• 2-pole design combined with an operational load of 690V AC and 25 to 400 Hz means it handles heavy loads with ease

• Signalling equipment
• Switching contactors
• Motor starters

With dimensions of 48 (H) x 26 (W) x 42mm (D) this block is ultra-compact, so it won't crowd your setup.

The block performs reliably in temperatures between -5°C and +60°C.
