DC Circuit Breaker GEYA GYM10-DC 2P C10A 4.5 kA

Product detailed description

The two-pole DC circuit breaker GEYA GYM10-DC 10 A is a specialized protective device designed exclusively for direct current (DC) circuits with a maximum operating voltage up to 500 V DC. You will primarily use it for the protection of individual photovoltaic panel strings, DC inputs of inverters, battery systems, and DC power distribution lines.

Unlike standard AC circuit breakers, it features a special arc extinguishing chamber and permanent magnets that ensure fast and reliable extinguishing of the DC electric arc occurring during switching under load or during a short circuit. The device safely disconnects both poles (+ and −) of the DC circuit.

Main advantages and applications

• Designed for photovoltaics and DC circuits: construction adapted for direct current up to 500 V DC.
• Two-pole version (2P): safe disconnection of the positive and negative branches (L+ / L−) of the circuit.
• Fast arc extinction: integrated arc extinguishing chamber with magnets prevents arc burning during switching.
• Protection of FVE strings: protects solar panels, charging regulators, and DC cabling from overcurrents and short circuits.
• Optical status indicator: clear window on the front side (red = on, green = off).
• Standard modular width: 2 modules (36 mm), easy mounting on TH35 DIN rail.
