⚡ Key Features

Genuine Siemens 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.
Rated for 24V AC coil circuits — match the suppressor voltage range to the contactor coil voltage for correct clamping.
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, cULus (select models) — meets Indian regulatory requirements for use in government, commercial, and industrial electrical installations.
Genuine authorised Siemens 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 3RT2926-1ER00 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 3RT2926-1ER00 clamps this transient at source. It is strongly recommended whenever a PLC, electronic timer, or sensitive control circuit switches the coil.

Q: Does the 3RT2926-1ER00 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.
