Auxiliary contact Schneider Electric ZENL1111, 1 NO contact, model 264602

Schneider Electric ZENL1111 auxiliary contact supplies a single normally open (1 NO) changeover point intended for use with compatible contactors and motor starters. Designed for signaling and control circuits, it provides reliable feedback on the main device state and can be mounted according to the equipment manufacturer's instructions. The compact design suits both industrial panels and building automation switchgear where an additional contact is needed for monitoring or interlocking.

Advantages

The accessory delivers a single clean switching element with defined mechanical and electrical characteristics to ensure predictable operation in control circuits. It is engineered to integrate with Schneider Electric contactors and starters, offering straightforward mounting and consistent contact action over many cycles. The component's form factor and contact arrangement simplify wiring for status indication, auxiliary control paths, and interlock functions.

Suitable for

• Signaling circuits for contactors and motor starters
• Auxiliary state feedback to PLCs, relays or indicator lamps
• Interlock and safety control circuits in industrial installations
• Retrofit or expansion of existing control panels requiring a 1 NO auxiliary contact

When it may not be suitable

This auxiliary contact provides only a single normally open contact and is not appropriate where multiple auxiliary contacts or normally closed contacts are required. It is intended to be mounted to compatible Schneider Electric devices or as specified by the equipment manufacturer; it may not fit or function correctly with non-compatible brands or models.

Key specifications

• Contact configuration: 1 normally open (1 NO)
• Intended use: signaling and control circuits with contactors and motor starters
• Mounting: designed for attachment to compatible switching devices as per manufacturer instructions
• Application environment: industrial and building automation panels
• Function: state feedback, auxiliary switching, interlock support

How to use

Install the auxiliary contact onto a compatible contactor or starter following the mounting procedure recommended by the device manufacturer. Connect the contact into the control or signaling circuit using appropriate wire sizes and termination methods for the expected current and voltage. Verify correct mechanical engagement and electrical continuity in both the rest and operated states before placing the equipment into regular service. Periodically inspect the connection points and contact function as part of routine maintenance.

What to consider before purchase

• Confirm mechanical compatibility with your contactor or starter model and mounting position
• Ensure a single normally open contact meets the control or signaling requirements
• Check the intended application environment (industrial panel, building automation) for suitability

Usage recommendations

Use this auxiliary contact for straightforward feedback and interlock tasks where a single normally open switching element is sufficient. For integration with PLCs or indicator circuits, route wiring through protective terminals and verify electrical ratings match the control circuit level.
