Schneider Electric LADN01 Auxiliary Contact Block Tesys

Product Description

The Schneider Electric LADN01 is an auxiliary contact block designed as an add-on accessory for TeSys D and TeSys F series contactors. It expands the switching capacity of a contactor by providing additional normally open or normally closed contact positions beyond those built into the base unit. The LADN01 mounts directly to the contactor body without tools or adapters, making it a field-installable accessory. At 0.05 pounds and a compact footprint of 2 inches by 1.7 inches by 1.1 inches, it adds minimal bulk to the assembled contactor. Electricians and panel builders use this block when a control circuit requires more auxiliary switching points than the base contactor supplies.

The LADN01 is used in motor control centers, control panels, and industrial machinery where TeSys D or TeSys F contactors manage load switching. Typical applications include auxiliary interlock circuits, indicator lamp circuits, PLC input feedback loops, and safety interlock wiring. It is suited for both new panel builds and retrofit upgrades where additional control contacts are needed on an existing installed contactor.

Key Features

• Snap-on mounting attaches directly to compatible TeSys D and TeSys F contactor bodies
• Compact size — 2 inches tall, 1.7 inches wide, 1.1 inches in length — minimizes panel space impact
• Lightweight at 0.05 pounds, adding negligible load to the contactor assembly
• Designed as an OEM-style accessory for use in motor control and switching applications
• Single-unit packaging supports exact-quantity procurement with no forced overage

Compatibility

The LADN01 is compatible with Schneider Electric TeSys D and TeSys F series contactors as specified by the manufacturer.

Installation Notes

Installation of auxiliary contact blocks should be performed by a qualified electrician with the contactor fully de-energized and the panel isolated from its power source before any work begins. The block snaps onto the contactor body in the designated accessory slot — verify the slot is clear and undamaged before fitting. Wiring of the auxiliary contacts must comply with applicable NEC requirements for control circuit conductors. Do not force the block onto an incompatible contactor frame, as this can damage the contact mechanism.
