XL7-63 PV 2P 40A 800VDC Curve C Miniature Circuit Breaker

Product Description

The Magnetothermic XL7-63 PV 2P 40A 800VDC Curve C is designed for the DC side of demanding solar systems. It protects lines and equipment against overloads and short circuits, with reliable tripping and simultaneous opening of both poles to minimize DC arc risks. Its modular DIN design streamlines installation and allows for organized maintenance in field panels and inverter inputs.

Main Features

• 40 A rated for strings and branches with higher demand.
• Up to 800 V DC admissible voltage.
• 2P (positive and negative) with simultaneous disconnection.
• Curve C thermal-magnetic for balanced response.
• Format DIN 35 mm, IP20 on the front and self-extinguishing housing.

Advantages or Benefits

• Greater operational safety and protection for inverters and cabling.
• Facilitates maintenance interventions by completely isolating the DC circuit.
• Compact and scalable installation in professional solar panels.
• Reduces unwanted tripping while maintaining protection against real faults.

Purpose or Applications

String protection and disconnection in combiners, DC inputs of hybrid or grid inverters, commercial self-consumption, pumping, and small PV plants with branch currents up to 40 A.

Technical Specifications

Compatibilities

Fits in HT series watertight panels such as the HT-24WAYS 24 modules 2 rows. It is recommended to coordinate with 10×38 gPV fuse holders (no URL) and type 2 DC surge protectors XLSPD-PV 600V 2P; for the AC side, use residual current devices XID-63 4P Type A as per diagram.

The Magnetothermic XL7-63 PV 2P 40A 800VDC Curve C ensures reliable DC protection and clear disconnection in high-performance photovoltaic installations.
