LADN20, Schneider Electric Auxiliary Contact Block, 2 Contact, 2NO, Front Mount, TeSys

Schneider Electric Auxiliary Contact - LADN TeSys D Series

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.

Features and benefits:

• 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

• IEC 60947-5-1 associated fuse rating
• GG fuse <= 10 A
• BS 4795, EN 60947-5-1, IEC 60947-5-1
• CSA, UL certified
• IP2x Conforming to VDE 0106
• Thermally treated and protected to TH conforming to IEC 60068
• Ambient Air Temperature (AAT) for operation -5 to 60 °C

Applications

• Motor starters/Control systems
• Switching contactors/relay coils
• Control/Signalling equipment

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.

Note

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

Schneider Electric Auxiliary Contact Block, Screw Terminals, 5mA Minimum Switching Current - TeSys D Series - LADN20

Boost the safety and reliability of your TeSys D contactor or control relay with this auxiliary contact block from Schneider Electric. It simply clips into the front of your device, so it's a space-saving component that's quick to fit. With an instantaneous operation and a 2NO contact configuration, it's a nifty way to add to your switching capabilities without upgrading your contactor or relay. This means you can improve safety signalling, automatically letting your logic controller or operator know that your system is working well.

Features & Benefits

• Wide operating temperature range between -5°C and +60°C to handle harsh conditions
• Mechanical lifespan of 30,000,000 cycles means it's durable
• Screw clamp terminals keep connections secure

Applications

• Packaging equipment
• Processing machines
• Industrial pumps
• Generators

How sustainable is this auxiliary contact block?

A minimum switching current of 5mA means this auxiliary contact block doesn't need a lot of power to work. It's made with materials that are free from mercury and toxic heavy metals, so it's safe to handle and easy to recycle.
