XL7-63 PV 2P 63A 800VDC Curve C Miniature Circuit Breaker

Product Description

The Magnetothermal XL7-63 PV 2P 63A 800VDC Curve C is designed for high-power photovoltaic systems that require a higher rating per string. It provides protection against overloads and short circuits in direct current and, being 2P, simultaneously opens both positive and negative, minimizing the risk of DC arc. Its thermal-magnetic mechanism (curve C) ensures precise tripping, and the modular DIN format facilitates installation in combiners and field panels.

Main Features

• 63 A nominal for high-current strings.
• Up to 800 V DC admissible voltage.
• 2P with simultaneous disconnection of both poles.
• Curve C with thermal and magnetic protection.
• 6 kA breaking capacity (typical) and housing with IP20 front protection.

Advantages or Benefits

• Maximum safety and service continuity in demanding installations.
• Clear disconnection for operations and maintenance without voltage.
• Quick integration on DIN 35 mm rail and compact design.
• Curve C that prevents unwanted tripping and protects against real faults.

Purpose or Applications

Protection of DC strings and busbars in commercial/industrial installations, small plants, solar pumping, or systems with high-power inverters that require high ratings.

Technical Specifications

Compatibilities

Fits in HT series watertight panels such as the HT-24WAYS 24 modules 2 rows. Coordination with 10×38 gPV fuse holder base (no URL) and XLSPD-PV 600V 2P surge protector is recommended. In AC, use together with XID-63 4P Type A residual current devices as per design.

With the Magnetothermal XL7-63 PV 2P 63A 800VDC Curve C you have powerful and professional DC protection for high-current strings in modern photovoltaic installations.
