New GTM400 and GTM500 Bidirectional Contactors

15 September 2023

Sensata Technologies Introduces GTM400 and GTM500 Bidirectional Contactors.

Sensata Technologies has launched its new Gigavac GTM400 and GTM500 bidirectional contactors for applications up to 1500 Vdc and 400A /500A.
The new contactors are ideal for high-power applications that require reliable switching and DC circuit protection like energy storage systems, DC fast charging stations, and heavy-duty vehicles.

New GTM series excel in performance compared to competition, offering:

  • Increased current carry capability (reduced size and weight, increased battery life).
  • Best in class break performance (improved safety).
  • Advanced arc suppression performance (increased reliability and product life).
  • Unmatched short circuit performance (no rupture or fire risk).
  • Significant performance/cost ratio when compared to other available technologies.

The GTM400 and GTM500 are the first products released as a part of Sensata’s new GTM contactor family which feature glass-to-metal seals (GTMS) - an industry first in contactor design.
Glass-to-metal sealing is a technique used to create effective electrically-insulative hermetic seal technology.

Leveraging over 50 years of expertise in GTMS, Sensata has engineered its GTM series of contactors to ensure best-in-class performance and reliability.
