XL8-63 4P 32A 400V AC Curve C Miniature Circuit Breaker

Product Description

The Magnetothermic XL8-63 4P 32A 400V AC Curve C is a four-pole circuit breaker designed for three-phase circuits with higher demands. Its combination of thermal and magnetic tripping acts precisely in the event of overloads and short circuits, while the Curve C offers tolerance to inrush currents from motors, compressors, or power electronics, preventing unwanted tripping and preserving service continuity.

Main Features

• 4P, 32 A for 3F+N power lines.
• 400 V~ 50/60 Hz with high-visibility ON/OFF lever.
• Curve C with coordinated thermal and magnetic response.
• Breaking capacity up to 6 kA at low voltage.
• Installation on 35 mm DIN rail; compatible with busbars.
• Screw terminals for rigid/flexible cable and secure tightening.

Advantages or Benefits

• Comprehensive protection for wiring and high-consumption three-phase equipment.
• Fewer trips due to starting and greater operational continuity.
• Quick installation and simple maintenance in modular panels.
• Robust design and self-extinguishing materials for long service life.
• Facilitates selectivity and organization of professional panels.

Purpose or Applications

Three-phase subpanels, pumps and compressors, light machinery, climate control, AC distribution from three-phase inverters, and service lines in SMEs and commercial settings.

Technical Specifications

Compatibilities

Direct integration in HT-12WAYS/18WAYS/24WAYS panels; use together with XID-63 4P Type A 30 mA residual current devices, SPD AC Type II, disconnectors, and DIN busbars. Coordinate conductor sections and selectivity according to available short-circuit calculation.

The Magnetothermic XL8-63 4P 32A 400V AC Curve C offers powerful, reliable, and easy-to-install protection for high-demand three-phase circuits.
