GYM7DC New Energy High Voltage Circuit Breaker
GYM7DC series new energy high voltage DC circuit breaker is designed for high-voltage DC protection in photovoltaic, energy storage, and industrial DC applications. Featuring high short-circuit breaking capacity up to single-pole DC 1500V (Ics=10kA), it delivers exceptional reliability, high impulse voltage resistance, and stable performance under high ambient temperature conditions up to +50°C.
â—‰ Standard Compliance: Fully complies with UL 489 standard.
â—‰ Zero Arc Protection: Engineered for zero arc capability with arc extinguishing chamber design.
â—‰ High Voltage Performance: Single pole DC 1500V with Ics=10kA short-circuit breaking capacity.
◉ Flexible Wiring: Features no polarity requirements and no capacity derating for reversing lines or +50°C operation.
