High-voltage contactor uses aerospace technology

Completely sealed 150A single-pole single-throw normally open contactor can power switch both AC and DC up to 750V.

Gigavac has developed a completely sealed 150A single-pole single-throw normally open contactor that can power switch both AC and DC up to 750V.

Using Gigavac's EPIC extended performance impervious ceramic sealing technology, as used in advanced aerospace applications, the new GX11 can operate in harsh environments without the need for special protective packaging.

Measuring only 57mm in height, the GX11 sealed contactor with easy-connect industry standard chassis level power connections, can be mounted in any direction practically anywhere without having to bend the large connecting power cables or develop special bus bars.

The new GX11 is available with DC and AC coils.

Internal coil suppression is built-in for the DC coils.

Single pole, double throw (SPDT) auxiliary contacts rated at 2A are available as an option.

"We have studied industry needs extensively and have created a truly unique, low cost sealed multi purpose contactor".

"The GX11, with its simple, easy to understand ratings, makes it hassle free for all users", explains Pat McPherson, Gigavac's VP of Marketing: "It's very compact and requires only 28mA of coil power at 24V DC; and has no electronic coil economiser that can generate noise or become contaminated".

McPherson added: "The GX11 can operate at temperatures from - 55 to +75C (up to +125C with special coils), and can withstand terminal temperatures up to 175C; reducing the risk of fire or melt down should a failure or short occur elsewhere in the circuit".

The GX11 sells for US $93 each and is in stock for immediate delivery.
