SCHNEIDER ELECTRIC LA8DN11

Schneider Electric LA8DN11 Auxiliary Contact Block for TeSys D Description The LA8DN11 is a high-quality auxiliary contact block manufactured by Schneider Electric under the Telemecanique brand. It is designed to easily clip onto the front of TeSys D and TeSys F contactors. This unit expands the control and signaling capabilities of the contactor by providing one additional normally open (NO) and one normally closed (NC) contact. It is a standard component for creating interlocking circuits, status feedback, and complex control logic in industrial automation environments. Specifications Manufacturer: Schneider Electric (Telemecanique) Model: LA8DN11 Product Type: Auxiliary Contact Block Contact Configuration: 1 NO + 1 NC Mounting Type: Front Mount Rated Insulation Voltage (Ui): 660 V Conventional Thermal Current (Ith): 10 A Terminals: Screw Clamp Compatibility: TeSys D, TeSys F, TeSys K contactors (e.g., LC1D, CA2D) Label Info NEMA Rating: A600, Q600 Standards: IEC, NFC, VDE, BS, UL, CSA, JIS Application This auxiliary contact block is widely used in motor control centers (MCCs), industrial machinery, and automation panels. It is essential for applications requiring electrical interlocking between two contactors, providing feedback to a PLC, or signaling the operational state of a motor to an indicator lamp. Country of Origin This product was made in France. CO2 Impact By purchasing this pre-owned item, you are helping to avoid the emission of approximately 2.0 kg of CO2. This is comparable to the savings from driving a standard car for 10 kilometers. Availability This item is in stock and ready for immediate dispatch.

It simply clips onto the front face of a compatible TeSys D, TeSys K, or TeSys F contactor without the need for any tools. Ensure the contactor is de-energized before installation. Can this auxiliary contact block be used with safety circuits?While standard auxiliary contacts can be used for feedback, for certified safety applications, it is recommended to use specific safety-rated contactors and auxiliary blocks, such as those with mechanically linked, mirror contacts (e.g., LADN11G), to ensure reliable status feedback according to safety standards like EN ISO 13849-1. What is the significance of the A600/Q600 rating on the label?The A600/Q600 rating is a NEMA (National Electrical Manufacturers Association) standard code for pilot duty contact ratings. ‘A’ stands for AC voltage, and ‘Q’ for DC voltage. The ‘600’ indicates a maximum voltage of 600V. This code specifies the make/break current capacity at different voltages, ensuring its suitability for controlling coils of other contactors or relays in North American applications. profideals is not an authorized distributor, reseller, or representative of the products featured on this website.
