CHTAIXI DC Miniature Circuit Breaker C32 - 2-Pole, 1000V, 32A, DIN Rail Mount

Overview

The CHTAIXI DC Miniature Circuit Breaker C32 is a compact, rugged device designed to protect DC power distribution from overload and short circuits. This 2-pole unit is rated up to 1000V and 32A, making it a practical fit for modern DC networks such as solar PV installations, telecom power rails, and marine systems. It is built for DIN rail mounting, enabling tidy panels and fast replacement when service is needed. Secure wiring is supported via screw clamps for straightforward integration into existing control cabinets.

Smart protection for DC networks

When a fault occurs, the fast electromagnetic trip disengages the circuit almost instantly, helping limit fault current and reduce stress on conductors and devices. The DC arc extinguishing system uses magnetic forces to help quench the arc during switching, contributing to safer operation in DC environments. These features align with typical needs in solar PV arrays, battery storage systems, and other continuous DC power resources.

Key features at a glance

• Functions: Protects power distribution facilities from overload and short-circuit damage; usable for control and isolation.
• Fast trip: Electromagnetic trip responds instantly to a short circuit, helping to preserve circuit integrity.
• Arc extinguishing: DC arc extinguishing aided by a magnetic system improves switching safety.
• Application: Designed for DC power systems, solar PV systems, ship electric power systems, and similar DC networks.

Practical real-world scenarios

In a rooftop solar installation, the CHTAIXI C32 can sit between the PV array and the battery inverter, providing a clean, isolated break point and an added protective layer. In a shipboard DC power cabinet, its robust DIN-rail footprint keeps wiring organized while delivering reliable protection under demanding conditions. For industrial control panels, the compact form factor reduces panel depth while maintaining essential protection and isolation capabilities.

Why choose this DC breaker

• Compact and DIN-rail compatible for easy integration into existing panels.
• Suitable for DC systems such as solar PV, marine, and other DC networks.
• Clear, robust wiring via screw clamps ensures solid connections.

Important usage note

Always follow local electrical codes and manufacturer guidelines when selecting and installing circuit protection. Consider this device as a potential component to enhance DC protection and isolation in your system, offering possibilities for safer, organized power distribution.
