YINGHUA

YINGHUA RC Absorption Snubber Circuit Module

SKU CH-3MBG-91Q99

RC snubber module suppresses voltage spikes to protect relay contacts from surge damage

  • Protects relay contacts from arcing damage using RC snubber circuit
  • Reduces voltage spikes and electrical noise in switching applications
  • Suppresses surge transients to extend component lifespan
  • Simple module format for easy integration into existing circuits

RC Snubber Module for Relay Protection

This RC absorption module suppresses voltage spikes across relay contacts to extend switching life. It is designed for engineers and technicians protecting inductive loads in control panels, motor starters or solenoid circuits. The single-piece format suits bench testing, prototype work or low-volume maintenance where a compact snubber is required. Buyers needing DIN-rail mounting or pre-wired terminal blocks will not find those features here.

Simple parallel connection across contacts

Installation is a parallel solder or screw connection directly across the relay contacts, requiring only basic wiring tools. Polarity is not critical for the RC network, simplifying the hookup. The main difficulty is selecting a resistor and capacitor rating that matches the load voltage and current; an undersized snubber can overheat while an oversized one may slow contact opening. No configuration software or calibration is involved.

Highlights

  • Protects relay contacts from arcing damage using RC snubber circuit
  • Reduces voltage spikes and electrical noise in switching applications
  • Suppresses surge transients to extend component lifespan
  • Simple module format for easy integration into existing circuits

Questions about this item

How can I confirm the RC snubber module is protecting the relay contacts after installation?

Monitor the relay contacts for reduced arcing and measure voltage spikes across the module during switching; a functioning snubber will show suppressed transients.

What components are included with the YINGHUA RC absorption module and what must be sourced separately?

The package contains one RC snubber circuit module; mounting hardware, wiring, and the relay or contactor being protected are not included and must be purchased separately.
