XL8-63 Circuit Breaker 2P 40A 400V AC Curve C

Product description

The XL8-63 2P 40A 400V AC Curve C Miniature Circuit Breaker is a two-pole device designed to protect high-demand branch circuits at 400 V~. It integrates thermal and magnetic tripping to respond precisely to sustained overloads and short circuits, while the Curve C tolerates moderate inrush currents from motors and power equipment, ensuring service continuity.

Main features

• In 40 A for high-power loads or subpanels.
• 2P: simultaneous disconnection of both conductors.
• Curve C (coordinated thermal + magnetic protection).
• Breaking capacity up to 6 kA for low voltage.
• Mounting on DIN rail, ON/OFF indicator, and robust terminals.
• Compliant with IEC/EN 60898-1.

Advantages or benefits

• Safety and selectivity in high-consumption lines.
• Quick installation with DIN accessories and busbar combs.
• High mechanical and electrical reliability for continuous use.
• Easy inspection and maintenance due to its modular design.

Purpose or applications

High-section power lines, pumps and compressors, light machinery, plant subpanels, and AC outputs of inverters with high power in residential/commercial/light industrial applications.

Technical specifications

Compatibilities

Integrates with HT-12WAYS/18WAYS/24WAYS panels, XID-63 residual current devices (Type A 30 mA), type II AC SPD, disconnectors, and DIN comb busbars. Adjust conductor cross-section and selectivity according to available short-circuit current.

The XL8-63 2P 40A 400V AC Curve C Miniature Circuit Breaker is the solid and safe solution for protecting high-demand circuits with a clean and professional installation.
