XL8-63 4P 25A 400V AC Curve C Miniature Circuit Breaker

Product Description

The Magnetothermic XL8-63 4P 25A 400V AC Curve C is a four-pole modular circuit breaker for complete protection of three-phase networks with neutral. It combines thermal and magnetic tripping to respond to overloads and short circuits, and its Curve C characteristic provides adequate immunity to moderate inrush currents from motors, pumps, or power electronics, maintaining selectivity and service continuity.

Main Features

• 4 poles, 25 A: simultaneous disconnection of L1-L2-L3-N.
• 400 V~ 50/60 Hz with clear ON/OFF indication.
• Curve C (coordinated thermal + magnetic protection).
• Breaking capacity up to 6 kA at low voltage.
• Quick installation on 35 mm DIN rail; compatible with busbars.
• Screw terminals for rigid or flexible cable.

Advantages or Benefits

• Safety and reliability in three-phase distribution with neutral.
• Reduces nuisance tripping due to load startups.
• Clean installation and simple maintenance.
• Modular format that facilitates organized and selective panels.
• High durability due to self-extinguishing materials and robust mechanism.

Purpose or Applications

Three-phase power branches for pumps, ventilation, light machinery, subpanels, and AC distribution in commercial or residential self-consumption systems 3F+N.
