600 A sealed contactor

May 2010 Electrical Power & Protection

GIGAVAC has announced the GX16 – a low cost 600 A SPST (single pole single throw) normally open sealed contactor just 76 mm tall and weighing less than a kilogram. The GX16 further expands GIGAVAC’s line of EPIC sealed contactors – rated from 20 to 600 A continuous – that can switch both AC and DC voltages up to 750 V and are RoHS compliant.

The GX16 was developed for large all-electric or hybrid-powered vehicles, mining equipment, rail, as well as large solar and power back-up systems. The contactor is lightweight, requires low coil hold power, can be mounted in any position, and can be used in harsh environments including under water and at temperatures from –55 to 85°C (up to 125° with special coils). The dual coil design means one coil is automatically removed from the coil circuit once energised and only eight watts of coil power is required for continuous operation. An optional SPST-NO (normally open) auxiliary contact driven off the main armature gives true indication of the main contact position.
