Auxiliary contact Schneider Electric LC1D098E7 with 1 normally open and 1 normally closed contact, AC coil 48 V

Schneider Electric LC1D098E7 auxiliary contact module provides one normally open (NO) and one normally closed (NC) contact and is intended to expand the switching and signaling capabilities of compatible contactors and motor starters. The module is designed for AC control circuits at 48 V and fits installations where compact, modular auxiliary contacts are required to implement interlocks, status feedback or additional control functions.

Advantages

The auxiliary contact offers both a NO and a NC contact in a single compact module, allowing simultaneous changeover and monitoring functions without additional wiring space. Its design is compatible with typical contactor assemblies and supports AC coil control at 48 V for consistent electrical behaviour in control panels. The module facilitates straightforward integration into existing control and signaling circuits and reduces the need for separate relay devices for basic status feedback and interlocking.

Suitable for

• Expanding control and signaling functions of contactors and motor starters
• Interlocking circuits to prevent simultaneous operation of conflicting devices
• Status indication to PLCs, control panels or indicator lamps
• Small to medium industrial and commercial electrical installations

When it may not be suitable

This auxiliary contact module is not intended as a primary switching device for high-current loads; it is designed for control and signaling circuits. It is matched to contactor assemblies and may not be compatible with all types or brands of contactors without the appropriate mechanical mounting or adapter.

Key specifications

• Contact configuration: 1 normally open (NO) + 1 normally closed (NC)
• Control type: AC coil operation
• Control voltage: 48 V AC
• Mounting: modular attachment to compatible contactor bodies
• Typical use: auxiliary switching for signaling, interlocking and control circuit expansion

How to use

Mount the auxiliary contact module onto the compatible contactor according to the contactor manufacturer's instructions, ensuring secure mechanical engagement. Wire the NO and NC terminals into the control or signaling circuit using appropriate wire size and secure terminations. Verify correct polarity and control voltage for the AC coil (48 V) before energizing. Test the switching operation by actuating the main contactor and observing the auxiliary contact state to confirm correct interlock and feedback behaviour.

What to consider before purchase

• Ensure mechanical compatibility with the target contactor model and mounting system
• Confirm that 48 V AC is the correct control voltage for your control circuit
• Check that the contact configuration (1 NO + 1 NC) meets your signaling and interlocking needs
• Assess required wiring space and terminal accessibility in the control panel

Usage recommendations

Use the module for status feedback and interlock functions within control panels and motor starter assemblies. During installation, follow local electrical codes and Schneider Electric guidelines for mounting and wiring. For critical safety interlocks or high-current switching, combine with appropriate protective devices and ensure routine inspection of connections and operation.
