Arc Containment
Built for 1500V Systems
The ESM Series utilizes advanced **Ceramic Brazing Technology** to create a hermetically sealed arc chamber filled with hydrogen gas. This ensures:
- Safe Breaking: Capable of breaking up to 2000A at 1000V DC safely without fire or explosion.
- Zero Leakage: Ceramic-to-metal bond prevents gas leakage, maintaining performance over 20 years.
- Compact Pre-Charge: The ESM-20/40 models are specifically designed as compact pre-charge relays for protecting main contactors.
