XL8-63 4P 16A 400V AC Curve C Miniature Circuit Breaker

Product Description

The Magnetothermic XL8-63 4P 16A 400V AC Curve C is a 4-pole modular circuit breaker for comprehensive protection of three-phase networks with neutral. It combines thermal and magnetic tripping to act against overloads and short circuits, and its Curve C characteristic tolerates the typical inrush currents of small motors, pumps, or power electronics, preventing unwanted tripping.

Main Features

• 4P, 16 A for medium-consumption three-phase circuits.
• 400 V~ 50/60 Hz, visible ON/OFF indication.
• Curve C with coordinated response.
• Breaking capacity up to 6 kA.
• Quick mounting on DIN rail and compatibility with busbars.
• Robust terminals for rigid/flexible cable.

Advantages or Benefits

• Protects wiring and equipment in 3P+N networks with high reliability.
• Facilitates organized and selective panels due to its modular format.
• Quick installation and simple maintenance.
• Greater service continuity by avoiding tripping during startup.
• Self-extinguishing materials and durable mechanism.

Purpose or Applications

Three-phase subpanels, small motors, pumps, ventilation, power lines in commercial premises and SMEs, AC distribution in three-phase self-consumption systems.

Technical Specifications

Compatibilities

Integrates with HT-12WAYS/18WAYS/24WAYS panels, XID-63 4P Type A 30 mA residual current devices, type II AC SPD, isolators, and DIN busbars. Adjust conductor cross-section and selectivity according to available short-circuit calculation.

The Magnetothermic XL8-63 4P 16A 400V AC Curve C guarantees professional and long-lasting protection for your three-phase lines.
