CHTAIXI DC Miniature Circuit Breaker 2-Pole 1000V 63A | DC Isolator for Solar PV & DC Systems

Overview

The CHTAIXI DC Miniature Circuit Breaker is built to guard DC power distribution from faults while offering clean isolation in a compact enclosure. With 2 poles, it supports 1000 V DC circuits and up to 63 A, making it suitable for demanding DC environments where space is at a premium. The sturdy body, clear labeling, and DIN rail compatibility are designed to simplify panel integration and routine maintenance.

What this device does

• Functions: It protects power distribution facilities from overload and short circuits and also allows control and isolation of circuit segments.
• Fast trip: The electromagnetic trip responds quickly when a fault is detected, helping to limit damage and downtime.
• Arc extinguishing: A dedicated magnetic system assists with quenching DC arcs during switching, improving safety in DC networks.
• Versatile applications: Works in DC power systems for industrial equipment, solar PV installations, maritime power networks, and other DC configurations.
• Wiring and mounting: Features screw clamp wiring and 35 mm DIN rail mounting for straightforward integration into standard control panels.

Where to use

Ideal for environments where DC distribution requires reliable protection and easy isolation. In solar PV projects, it can sit between the arrays and the inverter, providing a fast disconnect path. In marine or shipboard systems, it helps isolate a DC distribution branch during maintenance. In telecom or data centers with DC rails, it supports safe operation by offering a clear point to interrupt power if needed.

Installation tips

• Mounting: Use 35 mm DIN rails for a snug, code-compliant installation with compatible enclosures.
• Wiring: Use screw clamp connections to secure conductors firmly while avoiding stray strands.
• Labeling: Ensure front labeling or panel legend clearly indicates the circuit being protected for faster fault diagnosis.

Durability and safety

The DC arc extinguishing system is designed to handle the challenges of switching DC loads, with a magnetic assist to help quench arcs. The two-pole design provides distinct separation between lines, supporting safer disconnection and easier maintenance in complex DC layouts. This unit is built to withstand typical panel environments while maintaining reliable performance across cycles.
