Roxburgh EMC, CRH Surge Protection Device 500 V ac Maximum Voltage Rating 3 Phase

Industrial grade RC contact suppressors comprising a resistor and capacitor in series to improve contact life

May be connected across switch or relay contacts to suppress interference generated when switching reactive loads
Self healing construction and self extinguishing case
500Vac rating - single-phase and three-phase versions
Moulded-in surface mounting lugs

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.
