DIHOOL 200A DC Breaker – 240V Battery Disconnect Switch for Solar & UPS

The DIHOOL 200A DC Breaker is a rugged, high current switch designed to protect and isolate DC power systems. Built for solar arrays, UPS pools, and battery banks, it combines a compact panel mount design with a robust thermal magnetic trip that responds to overloads and faults. The result is a device that helps you maintain safe operation in busy electrical environments while you monitor energy flow with confidence.

Key capabilities

• Thermal magnetic trip for circuit overload protection and safe isolation
• 200 A continuous current rating with solid reliability
• 30% silver content in moving contacts and 45% silver content in stationary contacts for durable conductivity
• Wide voltage range: DC 12 ~ 250 V and AC 90 ~ 240 V; short circuit breaking capacity 25 kA
• Compact dimensions 164 mm × 43 mm × 108 mm; panel mounting via screws
• Designed for DC applications such as photovoltaic systems, UPS, battery banks, and data centers

Practical use cases include a main disconnect at a solar power station, a protective stop between a battery bank and inverters, or a quick isolation point during maintenance. The durable enclosure and screw mounting support secure installation on standard control panels. The product is built to operate alongside other DC and AC equipment in mixed environments, including workshops and commercial facilities.

Why consider this DIHOOL breaker

• Reliably interrupts high current in DC circuits to prevent damage and facilitate safe service
• Silver alloy contacts reduce resistance wear and improve longevity under frequent switching
• Compact form factor fits in tight electrical panels while leaving room for other components

Specifications at a glance provide quick reference for integration decisions. Use as a main power switch in solar setups, a protective disconnect for UPS and data center configurations, or as a controllable node in a larger energy management strategy. While outcomes depend on system design, many users value the clarity, protection, and uptime potential the device can contribute to a well organized power architecture.
