ESS Power Terminal Assembly

The ESS Bolt Power Connector is a fixed, bolt-on power termination component designed for high-current DC connections in energy storage systems. Unlike plug-and-socket connectors, it provides a rigid electrical interface intended for permanent or semi-permanent installation, where mechanical stability and contact reliability are prioritized.

The connector is used to directly terminate cables or busbars within battery systems and DC power distribution paths, forming a secure current-carrying junction protected by an insulated housing. Color-coded enclosures enable clear polarity identification, while the enclosed structure helps reduce the risk of accidental contact and improves overall system safety.

Rated for DC applications up to 1500 V and current levels from 125 A to 200 A, the ESS Bolt Power Connector is suitable for stationary energy storage environments operating across a wide temperature range from –40 °C to +125 °C. Its flame-retardant housing and high insulation performance make it a dependable solution for high-current termination points where long-term stability and protection are required.
