RS PRO presents this 3-way chassis mount chassis package as part of its electronic components range. Two flexible wire ended single and three phase contact arc suppressors designed specifically to reduce contact arc when switching reactive loads.
These RC suppressors are suitable for industrial applications employing high power control circuitry. May be connected across a switch to improve contact life or in a parallel delta configuration to protect thyristors and solid state relays.

Capacitors store energy when they are connected to a voltage source in a circuit, for example when connected to a battery or electrical source. The capacitor will charge up to the same voltage as the voltage it is connected to, it does this when a current flows.

Capacitors contain two metal plates, and a dielectric material in between those two plates. An electric field is formed when voltage is applied over the plates. One plate collects negative charge the other positive. The effect of a capacitor is called capacitance.

These devices are designed for connecting directly across a mains supply but should NOT be used in positions where failure of the capacitor would expose anyone to electric shock.
