Auxiliary contact Schneider Electric LC1D12BL — multicolour, DC contact rating 24 V

The Schneider Electric LC1D12BL auxiliary contact adds auxiliary switching and signaling functions to compatible contactors and control equipment. Housed in a multicolour enclosure, this auxiliary contact is specified for DC operation at 24 V and is intended to extend control circuits where additional changeover or signalling contacts are needed. It is designed to integrate with industrial and building automation systems and to provide a compact and consistent means of increasing available control points without altering the main contactor assembly.

Advantages

The multicolour housing enables easy visual identification and wiring grouping in control panels. Rated for DC 24 V contact operation, the unit offers predictable switching behavior for low-voltage control circuits. Its compact design preserves panel space and permits straightforward mounting alongside compatible contactors, helping to maintain a tidy and modular control configuration. The auxiliary contact is manufactured by a recognised brand, ensuring compatibility with standard installation practices and electrical safety conventions.

Suitable for

• Adding signaling contacts to motor starters and contactor assemblies
• Extending control circuits in industrial automation systems
• Building automation panels requiring additional auxiliary contacts
• Control cabinets where visual identification of auxiliary devices is beneficial

Key specifications

• Contact type: auxiliary switching contacts for control circuits
• Contact rating: DC operation at 24 V suitable for low-voltage control signals
• Housing: multicolour enclosure for visual identification
• Mounting: compatible with standard contactor integration and panel installations
• Application environment: industrial and building automation control systems

How to use

Install the auxiliary contact onto a compatible contactor or in the designated mounting position following the contactor manufacturers instructions. Connect the auxiliary contact terminals into the control circuit using appropriately rated wiring and secure connections. Verify polarity and DC supply characteristics where relevant, then test switching operation under no-load conditions before placing the circuit into normal service. Ensure all work complies with local electrical codes and safety procedures.

Recommendations

Use the auxiliary contact for signalling and interlocking tasks within 24 V DC control circuits. Regularly inspect terminals and mounting for secure attachment and corrosion; perform functional checks after installation and during routine maintenance to confirm reliable switching performance.
