DC circuit breaker GEYA GYM10-DC 2P C6A 4.5 kA

Product detailed description

The dual-pole DC circuit breaker GEYA GYM10-DC 6A is a specialized protective device designed exclusively for direct current (DC) circuits with a maximum operating voltage of 500 V DC. You will mainly use it to protect individual photovoltaic panel strings, DC inputs of inverters, battery systems, and DC power distribution circuits.

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 when disconnecting a loaded circuit or in the case of a short circuit. The device disconnects both poles (+ and −) of the DC circuit, with the polarity clearly marked according to the wiring. The rated breaking capacity of 4.5 kA provides sufficient safety margin for photovoltaic installations and DC distribution systems.

Main advantages and applications

• Designed for photovoltaics and DC circuits: construction adapted for DC voltage up to 500 V DC.
• Dual-pole version (2P): safe disconnection of the positive and negative branches (L+ / L−) of the DC circuit.
• Fast arc extinguishing: integrated arc extinguishing chamber with magnets prevents electric arc burning during switching off.
• Reliable 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.
