XL7-63 PV 2P 50A 800VDC Curve C Miniature Circuit Breaker

Product Description

The Magnetothermal XL7-63 PV 2P 50A 800VDC Curve C is a direct current circuit breaker designed to protect PV branches and inverter DC inputs against overloads and short circuits. With two poles to simultaneously open positive and negative, it offers safe disconnection during maintenance work. Its thermal-magnetic trip (curve C) provides stable response to transient peaks and sustained overcurrents, and its modular DIN rail format allows for quick and orderly installation in combiners and field panels.

Main Features

• 50 A nominal for higher current strings.
• Up to 800 V DC operating voltage.
• 2 poles (2P) with simultaneous disconnection of + and −.
• Curve C with thermal and magnetic protection.
• Format DIN 35 mm, front IP20 and self-extinguishing housing.

Advantages or Benefits

• Increases the safety of DC lines and the service life of the inverter.
• Facilitates maintenance by completely isolating the branch.
• Compact and scalable installation in professional panels.
• Curve C reduces nuisance tripping and acts on real faults.

Purpose or Applications

Protection and disconnection of photovoltaic strings, combiners, and inverter DC inputs in commercial self-consumption, light industry, solar pumping, and small plants.
