Omron STI KT-ARC 43127-0010 Noise Arc Suppression Network Kit Electrocube RC

Omron STI KT-ARC 43127-0010 Noise Arc Suppression Network Kit Electrocube RC

The Omron Scientific Technologies (STI) KT-ARC is a Noise and Arc Suppression Network Kit designed to reduce electrical noise and contact arcing in relay and motor control circuits. The kit contains two Electrocube RG1986-7 RC snubber networks — each a series resistor-capacitor assembly connected across a relay coil, contactor, or switched inductive load to absorb the voltage spike generated when current is interrupted. This is a new, unused kit in its original sealed bag.

Applications

RC snubber networks like the Electrocube RG1986-7 are standard components in industrial relay panels, motor starters, and programmable logic controller (PLC) output circuits. When a relay coil or contactor de-energizes, the collapsing magnetic field generates a large inductive voltage spike (back-EMF) that can damage solid-state outputs, cause false triggering in nearby circuits, and erode relay contacts over time. The RC snubber absorbs and dissipates this energy before it can propagate. The STI KT-ARC kit is specifically matched for use with Omron STI safety relay and light curtain systems, which commonly specify a suppression network for inductive loads connected to their output terminals. These kits are used in machine safety circuits, conveyor controls, and automated assembly lines where reliable relay operation and long contact life are required. The 600VDC rating and compact lead-wire form factor make these snubbers suitable for a wide range of 24VDC through high-voltage AC coil applications.
