DIHOOL DC 200A Breaker — 500V Battery Disconnect Switch for Main Power Station, UPS & Solar

Overview

The DIHOOL DC 200 Amp Breaker is a robust DC disconnect switch designed for main power rails in modern energy setups. It supports DC operation from 12V up to 500V and accommodates AC operation up to 480V, making it a versatile choice for solar arrays, UPS racks, battery banks, and data centers. A thermal magnetic trip provides fast, predictable response to overloads, while the unit remains easy to reset after a fault, helping to minimize downtime and keep your system on track.

With an emphasis on reliable contact performance, the breaker uses high‑quality contact materials to support steady current flow in challenging DC conditions. In daily use, that translates to smoother operation during switching, fewer false trips, and a clearer isolation when service or maintenance is required.

Key benefits

• Thermal magnetic trip for dependable overload protection
• Durable contacts with moving parts at 30% silver and stationary parts at 45% silver
• Wide voltage tolerance: DC 12V–500V; AC 90–480V
• Strong short‑circuit capacity up to 25 kA for demanding DC circuits
• Compact panel footprint: 164 mm x 74 mm x 108 mm; screw mounting for secure panel fit
• Designed for DC applications such as photovoltaic systems, UPS, battery banks, and datacenters

Real‑world applications

In solar installations, the breaker can serve as a dedicated DC disconnect to safely isolate arrays for maintenance. In UPS or battery systems, it provides a clear, local isolation point. Data center power rails benefit from robust protection within compact enclosures, helping to manage risk in critical workloads.

Beyond protection, the unit’s construction emphasizes long‑term reliability. The combination of silver content and a durable housing supports consistent performance across a range of DC systems, from residential setups to commercial installations.

Installation tips and care

• Mount on a panel with screws, ensuring a secure, vibration‑free fit
• Provide adequate ventilation and confirm wiring gauge matches system requirements

DIHOOL products are designed to support professional power protection without overpromising results. This breaker offers a flexible option for selective disconnection and circuit protection in a variety of DC power stations and enclosures.
