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

The GEYA GYM10-DC 6A two-pole DC circuit breaker is a specialised protective device designed exclusively for direct current (DC) circuits with a maximum operating voltage of up to 500 V DC. It is primarily intended for protecting individual strings of photovoltaic panels, DC inputs of inverters, battery systems and DC power distribution networks.. Unlike standard AC circuit breakers, it features a special arc-extinguishing chamber and permanent magnets adapted to quickly and reliably extinguish the direct current arc that occurs when a circuit is disconnected under load or during a short circuit.. The device features non-polarised or clearly marked polarity (depending on the wiring) and ensures reliable disconnection of both poles (+ and -) in a DC circuit. The rated breaking capacity of 4.5 kA provides a sufficient safety margin for photovoltaic installations and DC switchboards.. MAIN ADVANTAGES AND APPLICATIONS:. Specially designed for photovoltaic systems and DC circuits: Construction adapted for DC voltages up to 500 V DC.. Two-pole design (2P): Ensures safe disconnection of both the positive and negative branches (L+ / L-) of the DC circuit.. Rapid DC arc quenching: An integrated, magnet-assisted quenching chamber prevents the electric arc from burning out upon disconnection.. Reliable protection for PV strings: Protects solar panels, charge controllers and DC cabling against overcurrent and short circuits.. Visual contact status indicator: A clear window on the front panel indicates the device’s status (red = on / green = off).. Standard modular width: Available in a 2-module width (36 mm) with simple mounting on a DIN rail (TH35).. ELECTRICAL AND TECHNICAL SPECIFICATIONS. Brand / Manufacturer: GEYA. Model series: GYM10-DC.
