Why Choose the IMO RC-MCN-400 Coil Suppressor?
The IMO RC-MCN-400 is a compact RC coil suppressor module designed to reduce voltage spikes, switching transients and electromagnetic interference generated by industrial contactor coils. Developed for use with IMO MC10 to MC74 contactors, it helps protect PLCs, relays, timers and other sensitive control equipment from coil-induced electrical disturbances.
When a contactor coil is de-energised, the collapsing magnetic field can produce a high-voltage transient. The RC-MCN-400 absorbs and limits this transient, helping improve control-circuit stability, reduce electrical noise and extend the service life of connected switching and automation components.
Suitable for 230–415 V AC at 50/60 Hz and DC control circuits, the IMO RC-MCN-400 features a convenient front-mounted design with flying cable leads. Its compact construction enables straightforward installation on compatible contactors in machinery, motor-control panels and industrial automation systems.

Reliable Coil Protection for Industrial Control Systems
Contactor coils are inductive loads that can generate significant voltage transients when switched off. Installing the IMO RC-MCN-400 across a compatible coil helps absorb this stored energy and reduce the resulting voltage peak.
By limiting electrical transients, the suppressor can improve the reliability of nearby electronic control devices and reduce nuisance operation caused by electromagnetic interference. Its purpose-designed mounting arrangement makes it a practical accessory for new control-panel builds, machine installations and maintenance upgrades.
Typical Applications
- IMO MC10 to MC74 contactor installations.
- Industrial motor-control panels.
- PLC-controlled machinery and automation systems.
- Motor starters and switching circuits.
- Electrical control cabinets.
- OEM machinery and production equipment.
