Hi Voltage Spike Suppressor


Protect your expensive electronics

Fitted to all chassis looms we produce, the high voltage spike suppressor is now available as a stand-alone part made in-house at RRR Engineering. Designed to suppress all voltage spikes over 20V, they most likely to appear when the battery isolator is disconnected while the engine is running.

All suppressors came in heat shrink Raychem DR25 and glued with ResinTech RT125.
