DIHOOL 200A DC Breaker 500V Battery Disconnect Switch — 2‑Pole Thermal‑Magnetic Protection, Front‑Accessible

The DIHOOL 200 Amp DC Breaker is a front-accessible thermal-magnetic battery disconnect switch designed to protect and isolate high-current DC systems up to 500V.

This compact two-pole unit delivers overload and short-circuit protection for photovoltaic arrays, battery banks, UPS systems, datacenter racks, and portable power stations. Built for DC applications where reliable isolation and easy front-panel installation matter, it combines thermal and magnetic trip mechanisms to respond to prolonged overloads and instantaneous short-circuit events.

How does this breaker protect my DC battery system?

The DIHOOL breaker uses a thermal-magnetic trip design that reacts to two different fault types: heat buildup from sustained overloads and magnetic response for sudden short circuits. This layered protection helps prevent wiring damage, component failure, and unsafe conditions by interrupting current flow when thresholds are exceeded.

• Thermal element trips on prolonged overcurrent to prevent overheating
• Magnetic element reacts instantly to short-circuit surges
• 2-pole configuration isolates both positive and negative/return DC conductors
• Rated for continuous 200A operation at voltages up to 500V DC

Is installation straightforward for front-panel or compartment mounting?

Yes — the breaker is engineered for accessible front installation so you can mount and service it without reaching into cramped compartments. Terminal placement and mounting dimensions allow quick integration into switchboards, combiner boxes, and battery enclosures.

• Front-accessible terminals for easier wiring and maintenance
• Compact 2P size: 65mm x 150mm x 69mm for space-efficient layouts
• Standard mounting holes and clearances for retrofit or new panels
• Labeling-friendly front face to identify circuits at a glance

Will this breaker work with solar arrays, UPS, and datacenter batteries?

Designed specifically for DC applications, the DIHOOL 200A breaker is compatible with photovoltaic systems, battery banks used by UPS and data centers, and power station configurations. It protects the DC side of these systems where high currents and potential faults demand rapid disconnection and isolation.

• Suitable for PV systems, battery disconnects and combiner boxes
• Appropriate for UPS DC buses and datacenter battery cabinets
• Works in portable or stationary power stations rated within specifications
• Prevents backfeed and enables safe maintenance and service

What are the key specs and practical benefits I should know?

The breaker’s headline ratings are 200 amps and 500 volts DC, with a compact two-pole form factor that balances current capacity and installation footprint. Its front-accessible design and dual trip mechanisms reduce downtime and simplify routine checks or replacement.

• 200 A continuous current rating; 500 V DC maximum voltage
• Thermal-magnetic trip for overload and short-circuit protection
• Dimensions: 65 mm x 150 mm x 69 mm for compact panel integration
• Front-accessible for maintenance, wiring, and faster troubleshooting

Who is this for? Installers, system integrators, and facility managers who work with DC power — from rooftop solar installers to UPS technicians and builders of portable power stations — will value the DIHOOL 200A breaker. It’s aimed at projects that need reliable DC protection, clear isolation, and convenient front-panel servicing without sacrificing current capacity or safety features. If you need a durable, easy-to-service DC disconnect for systems up to 500V, this breaker is built for that role.
