Our Contactor Portfolio
EVM Series (Main Contactor)
The flagship solution for Electric Vehicle main battery disconnects. Hermetically sealed ceramic chamber filled with Hydrogen gas for ultimate safety.
ESM Series (1500V Storage)
Specialized for Energy Storage Systems (ESS) and Solar Inverters. High insulation resistance and 1500V breaking capability.
EVG Series (General Purpose)
Cost-effective ceramic brazed contactor. Offers the safety of hydrogen sealing in a standard industrial footprint.
EVI Series (Industrial Epoxy)
Robust epoxy-sealed design for industrial power supplies, UPS, and light electric vehicles (Forklifts, Golf Carts).
Why Technology Matters
Used in EVM, ESM, EVG. The contact chamber is made of ceramic and brazed to metal, creating a true hermetic seal. We fill it with Hydrogen mixed gas.
- ✔ Zero Arc Leakage (Safety)
- ✔ No Contact Oxidation (Long Life)
- ✔ Withstands >1000V DC Arcs
Used in EVI Series. A robust industrial sealing method providing IP67 waterproof protection. Excellent for environments where extreme high voltage arcing is less critical.
- ✔ Dust & Waterproof
- ✔ High Mechanical Strength
