New GV210 series contactors from Sensata Technologies enable safe, efficient operation in electrification applications

25 June 2020

Sensata Technologies announced the availability of the new GV210 Series of hermetically sealed gas-filled contactors which offer high performance in a compact package for applications carrying 150 A and below at 12 to 900 VDC. The series is the latest addition to Sensata’s GIGAVAC brand product line and is suitable as the main contactor for rapidly electrifying applications such as forklifts, home energy storage and small electric vehicles (EVs) as well as the pre-charge contactor in larger battery pack applications such as utility-scale energy storage and large EVs.

The GV210 can efficiently carry up to 150 A continuously with low power losses. Capable of high pulse currents for fuse coordination, the contactor is also able to switch loads which enables safe operation. The hermetic seal exceeds IP67 and IP69 and prevents oxidation, allowing for reliable operation in corrosive or wet applications across a long mechanical lifetime of one million cycles. With an intrinsically safe design that Source: Sensata TechnologiesSource: Sensata Technologiesis not mounting position sensitive, the GV210 series is suitable for use in a wide variety of installations in hazardous classified operating environments. The ability to switch and carry high currents on modest size conductors makes this series a more capable solution than open air contactors.

Main contactor solution for electrification applications with small battery packs

At 52 mm tall with a 40 mm diameter, the gas-filled GV210 contactor weighs less than 200 grams, enabling lightweight and streamlined packaging in often space-restricted equipment. In small lithium-ion battery packs in the 12 V DC to 900 V DC range at continuous operating currents up to 150 A, the GV210 is ideal as a main contactor on both the positive and negative conductors. This includes applications with continuous power levels in the 3 kW to 100 kW range such as forklifts, aerial work platforms, automated guided vehicles, golf carts, motorcycles, drones, home energy storage and small battery pack chargers.

Quality contactors for higher performing lithium-ion battery chargers

As the performance of lithium-ion batteries increases and cost decreases, more applications are turning to these devices, which require higher performing chargers with quality contactors. With its robust hermetic seal and economical design, the GV210 Series is well-suited for applications where contactors play a critical safety role, such as keeping the plug unenergized when it is not plugged into a compatible battery pack.

Ideal pre-charge contactor for large battery system start up

While higher power main contactors such as GIGAVAC’s higher current GV and GX family products are required in applications above 150 A, as in utility-scale energy storage and large EVs, pre-charge contactors are also needed to help the system start-up smoothly without damaging key components. The GV210’s ability to hot switch in order to charge the load’s capacitors and maintain high voltage isolation once startup is complete makes it ideal for use in the pre-charge circuit.
