XL7-63 PV 2P 20A 800VDC Curve C Miniature Circuit Breaker

Product Description

The Magnetotérmico XL7-63 PV 2P 20A 800VDC Curve C is a direct current circuit breaker specifically designed to protect photovoltaic lines and strings against overloads and short circuits. With two poles and a working capacity of up to 800 V DC, it integrates easily into field panels and combiner boxes, providing electrical safety and appropriate selectivity with the rest of the installation's protections. Its curve C and thermal-magnetic mechanism ensure reliable tripping both in the event of sustained overcurrents and sudden faults, protecting modules, wiring, and inverters. Its modular format for DIN rail facilitates installation, maintenance, and future system expansion.

Main Features

• 2 poles (2P) for simultaneous disconnection of the positive and negative of the string.
• 20 A nominal rating for protection of medium power branches.
• Up to 800 V DC, suitable for high-voltage panel strings in self-consumption and commercial applications.
• Curve C thermal-magnetic: balanced tripping in case of overloads and short circuits.
• 35 mm DIN rail mounting, high-retention screw terminals.
• Front IP20, self-extinguishing housing and compact design for dense panels.

Advantages or Benefits

• Dedicated DC protection that increases the safety and reliability of the photovoltaic installation.
• Double-pole disconnection reduces risks during maintenance work.
• Quick installation: modular DIN format and accessible terminals for rigid or flexible cable with ferrule.
• Curve C is ideal for lines with moderate peaks, avoiding unwanted tripping and protecting electronics.
• Allows for clear selectivity with gPV fuses and DC surge arresters, simplifying the design.

Purpose or Applications

Protection and disconnection of photovoltaic strings, DC inverter inputs, field panels, and combiners in residential, commercial, solar pumping, or light industrial systems. Also useful in other direct current applications within the specified voltage and current range.

Technical Specifications

Compatibilities

Integrates into HT series watertight panels such as the HT-24WAYS IP65 24 modules 2 rows. Can be coordinated with 10×38 gPV fuse holders (no URL) for string protection and with DC Type 2 surge arresters (e.g. XLSPD-PV 600 V 2P, no URL). Use MC4 connectors and solar cable suitable for the current and temperature.

The Magnetotérmico XL7-63 PV 2P 20A 800VDC Curve C is the safe and professional choice to protect your photovoltaic branches, providing reliability, clear disconnection, and an orderly, durable installation.
