Description

DC Miniature Circuit Breaker – 4 Pole, 1000V (YRO YRL7-63DC) | 16A / 32A

Deliver complete 4-pole DC circuit protection with the YRO YRL7-63DC DC Miniature Circuit Breaker, a non-polar, photovoltaic-grade MCB engineered for overload and short-circuit protection in high-voltage DC systems. Ideal for DC combiner boxes, battery bank switching, and string-level solar PV protection, this 4-pole unit offers wide-circuit coverage in a compact DIN-rail footprint — making it the go-to choice for larger DC installations requiring multi-pole isolation.

Built with a high-grade flame-retardant thermoplastic housing that is impact-resistant, self-extinguishing, and recyclable, the YRL7-63DC is designed to perform reliably in demanding outdoor and industrial environments. The classic U-tunnel terminal design locks conductors firmly in place for secure, vibration-resistant connections, while the optimized internal airflow keeps adjacent breaker temperatures low for consistent, long-term performance.
