CHTAIXI DC MCB 2P 500V 80A — Solar DC Disconnect Switch, DIN Rail Mount

The CHTAIXI DC MCB is a robust two pole circuit breaker designed for DC power systems. Rated at 500V and 80A, it serves as a reliable disconnect switch in solar PV installations and other DC networks. Built to endure the demands of continuous DC operation, this unit combines protection with clear visibility for quick decisions in the field.

Key protection starts with overload and short circuit safeguards, paired with a magnetic arc extinguishing system that helps stabilize switching. The contacts use a durable silver alloy for reliable, low resistance performance, while the flame retardant shell provides a protective enclosure in busy electrical environments. A color indicator keeps you informed at a glance, so you can assess status during routine checks or after ongoing system activity.

Why choose this DC MCB for your setup

Designed to fit solar and other DC power distributions, this model serves as a dependable high current disconnect switch. Its 2P configuration supports common DC layouts, while the 80 A rating accommodates typical PV arrays, battery banks, and DC distribution points. The architecture favors quick isolation when maintenance or troubleshooting is required, without compromising safety or control.

• ARC EXTINGUISHING: Magnetic assistance helps stabilize arcs during disconnection, aiding safer operation.
• QUALITY: Silver alloy contacts minimize contact resistance and wear for longer life; flame retardant shell enhances durability.
• INDICATOR: A color indicator provides immediate visual status, reducing inspection time on busy panels.
• APPLICATION: Ideal for solar photovoltaic systems and other DC distribution networks that demand reliable isolation.

Installation is straightforward for professional installers. The unit is designed for 35 mm DIN rail mounting and uses screw clamp wiring. If you are using soft silicone wire, ensure the wire end is first crimped with copper to secure a solid connection. This MCB supports efficient integration into existing DC racks while maintaining a clean, organized panel layout.

Practical use cases and real-world benefits

In a solar installation, this MCB can be positioned between the array and the inverter to provide a clear, accessible disconnect point. In a battery storage setup, it offers a reliable means to isolate the DC line during maintenance or testing. The combination of a high current rating, solid contacts, and a visible status indicator helps technicians make quick, informed decisions in the field without overstating outcomes.

While no single component guarantees performance in every scenario, this DC MCB is designed to combine safety, reliability, and ease of use in demanding DC environments. It is a practical option for installers seeking a compact, DIN rail mounted solution with clear indicators and robust construction.
