XL8-63 Circuit Breaker 2P 20A 400V AC Curve C

Product Description

The Magnetothermic XL8-63 2P 20A 400V AC Curve C is a two-pole modular circuit breaker that combines thermal protection (prolonged overloads) and magnetic protection (short circuits) for 400 V~ lines. Its Curve C characteristic provides immunity to moderate inrush peaks present in typical loads (small motors, switched-mode power supplies, pumps, compact HVAC equipment, or electronics associated with inverters), preventing unwanted tripping and ensuring rapid disconnection in the event of severe faults. Constructed from self-extinguishing materials and featuring a high-reliability mechanism, it provides safety, selectivity, and easy maintenance in residential, commercial, or self-consumption panels.

Main Features

• In 20 A for general-purpose circuits with medium consumption.
• 2 poles: simultaneous disconnection of phase+neutral (or two phases) for increased safety.
• Curve C with coordinated thermal and magnetic tripping.
• Breaking capacity up to 6 kA (standard conditions), high interruption capacity.
• Clear ON/OFF indicator and quick snap-in on 35 mm DIN rail.
• Robust terminals for rigid or flexible cable and busbar combs.

Advantages or Benefits

• Protects wiring and loads, reducing faults and downtime.
• Good balance between inrush immunity and short-circuit response.
• Facilitates organized panels thanks to its modular DIN format.
• High durability due to its construction and self-extinguishing materials.
• Easy visual diagnosis and safe operation.

Purpose or Applications

Power and lighting branches, pumps and treatment units, general-purpose outlets, subpanels, AC outputs of inverters, and small industrial equipment. Suitable for residential, commercial, and solar panels (AC side).

Technical Specifications

Compatibilities

Installable in HT-12WAYS/18WAYS/24WAYS watertight panels with busbar combs, XID-63 residual current devices (Type A 30 mA), and type II AC SPD. Select cable section and selectivity according to panel design.

The Magnetothermic XL8-63 2P 20A 400V AC Curve C offers reliable, selective, and easy-to-integrate protection for medium-consumption circuits in modern installations.
