DC Switch EARU MCB 1000V 20A 2P

Product Description

The EARU DC MCB Switch 1000V 20A 2P is a direct current circuit breaker designed to protect photovoltaic strings and DC circuits against overloads and short circuits. With C curve, two poles, and a permissible voltage of up to 1000 VDC, it ensures safe disconnection in DC PV panels and combiner boxes with DIN rail mounting.

Main Features

• Rated current: 20 A · C curve (series with B/D available).
• Permissible voltage: up to 1000 VDC on 2 poles.
• Modular mounting on 35 mm DIN rail (2-module width).
• Self-extinguishing thermoplastic body · IP20 (in enclosure).
• Compliant with IEC 60898 / 60947-2 (breaking capacity as per label).

Advantages or Benefits

• Clear string disconnection for maintenance and safety.
• Current rating selection to match the actual Isc of the PV field.
• Compatibility with modular panels and combiner boxes.
• Greater service continuity and quick reset after tripping.

Purpose or Applications

Protection of PV strings between generator and MPPT, subfields in string boxes, and other DC lines within its range. Not an AC device nor for LV battery banks; use specific low-voltage protections in those cases.

Technical Specifications

Compatibilities

Use with MPPT inputs of solar inverters and DC PV panels (strings of Trina panels or others). Coordinate with type 2 DC SPD and main generator isolator.

EARU DC MCB Switch 1000V 20A 2P is a professional solution for demanding renewable energy projects. It increases safety, optimizes the panel, and improves the efficiency of your installation.
