DIHOOL 100 Amp DC Disconnect Switch for Main Power, UPS, Solar

Powerful DC isolation for critical equipment

Designed to cleanly interrupt DC power in main power stations, UPS units, solar arrays, and battery banks, the DIHOOL 100 Amp DC Disconnect Switch offers a reliable, maintenance-friendly isolation point. Its thermal magnetic trip responds to overloads with a decisive action, helping protect wiring and components while keeping service windows safe and straightforward.

Beyond protection, the device emphasizes durability and consistent contact performance. The moving contacts carry about 30% silver content, while stationary contacts feature roughly 45% silver content. This combination supports steady conductivity and steadier operation even after repeated switching, which translates into a predictable, dependable user experience in daily system management.

Technical range and protection

The switch accommodates a broad voltage window: DC 12V to 250V and AC 90V to 240V. It carries a short-circuit breaking capacity up to 25 kA, giving you a robust line of defense in surge or fault conditions. Its compact footprint (150 mm x 86 mm x 36 mm) is designed for panel installations and can be mounted securely using screws, helping you maintain a neat, accessible control interface.
