⚡ Key Features

Genuine Schneider Electric OEM accessory — manufactured to the same specification and tested to the same standards as the parent device; ensures mechanical and electrical compatibility that third-party alternatives cannot guarantee.
Coil surge suppressor module — absorbs the voltage transient generated when the contactor coil de-energises, protecting PLC transistor outputs and nearby electronics from switching spikes.
Clips directly onto the contactor coil terminals (A1/A2) — no panel space, wiring, or separate mounting required.
Direct clip-on or screw-mount to parent device — fits without panel modification or additional wiring between the accessory and main device; field-retrofittable.
Manufactured to IEC 60947 (tested as part of the parent device certification) — complies with the applicable Indian BIS and IEC international standards for this product category.
BIS certified, CE marked, RoHS compliant — meets Indian regulatory requirements for use in government, commercial, and industrial electrical installations.
Genuine authorised Schneider Electric product — sourced directly from the official distribution network with full manufacturer traceability and warranty.
GST invoice provided for India orders — valid for corporate procurement, government project orders, and public tender supply via myelectric.in.
Worldwide export available — UAE, Singapore, UK, USA, Sri Lanka & more. Contact +91 94814 00316 for bulk pricing and international shipping.

❓ Frequently Asked Questions

Q: Why fit the LA4DC1U suppressor module on a contactor coil?

A: When a contactor coil de-energises, the collapsing magnetic field generates a high-voltage transient (several hundred volts to kV) that can destroy PLC transistor outputs, weld small relay contacts, and disturb nearby electronics. The LA4DC1U clamps this transient at source. It is strongly recommended whenever a PLC, electronic timer, or sensitive control circuit switches the coil.

Q: Does the LA4DC1U suppressor type affect contactor drop-out time?

A: Yes, slightly. RC suppressors and varistors add minimal delay (a few milliseconds) and are suitable for almost all applications. Diode suppressors (DC coils only) give the slowest drop-out — relevant only in fast-reversing or braking applications where contactor release time matters. For standard motor starting duty, the difference is negligible.
