Build a More Organized Solar Protection Panel

A well-planned solar installation starts with components selected for the circuit they serve. This EARU solar DC circuit breaker combines two-pole operation, overload and short-circuit protection, and 35 mm DIN-rail mounting in a compact panel-ready format. Select the current rating your system requires, then give the installation a clearly marked, accessible switching point.

Key Benefits

• DC overload and short-circuit protection — Provides a protective switching component for a correctly designed, compatible DC distribution circuit.
• Linked two-pole handle — Operates both poles together through one prominent red control for straightforward manual switching.
• Nine selectable current ratings — Choose from 6A, 10A, 16A, 20A, 25A, 32A, 40A, 50A and 63A to match the circuit design rather than using a one-size-fits-all rating.
• 35 mm DIN-rail mounting — Fits a compatible rail-based panel layout for a neat, organized installation.
• Visible position windows — Make the indicated open or closed contact position easier to read at the front of the breaker.

Whether you are assembling a compatible photovoltaic panel or updating a DC distribution enclosure, clearly identified components make the finished layout easier to navigate. The white housing, red linked handle and front-facing markings keep the switching point distinct among the other panel components.

Selection and Installation

This listing offers individual EARU EACBDC-63 two-pole breakers with a stated DC 1000V rating and C tripping curve. The selected amperage is the rated current, not an adjustable setting. Use qualified electrical installation and follow the manufacturer's polarity and terminal markings. Match the breaker to the circuit voltage, conductor rating and available fault current. The listed IP20 protection calls for an appropriate installation enclosure rather than direct weather exposure.

Frequently Asked Questions

What does this solar DC circuit breaker do?

It provides overload and short-circuit protection for a compatible DC circuit when correctly selected and installed. It is a circuit component, not a complete solar protection system.

Which current ratings are available?

The available options are 6A, 10A, 16A, 20A, 25A, 32A, 40A, 50A and 63A. Each option is a separate fixed-current rating.

What does two-pole operation mean here?

The breaker has two poles connected by a shared handle, allowing both poles to be operated together. Follow the polarity and connection diagram marked on the unit.

How does it mount inside a panel?

It mounts on a compatible 35 mm DIN rail. Installation requires suitable wiring, terminals and an enclosure appropriate for the location.

Can it be installed outdoors without an enclosure?

No. Its listed protection class is IP20, not a weatherproof rating. Outdoor installations require a suitably rated enclosure and qualified electrical installation.
