Reliable DC Circuit Protection for Every Solar PV System.
Solar PV systems operate on high-voltage DC — and standard AC circuit breakers simply aren't designed for it. The TOMZN TOB7Z-63 2P DC 1000V Mini Circuit Breaker is purpose-built for photovoltaic applications, providing safe and reliable overload and short circuit protection for DC solar strings, combiner boxes, and battery systems. CE certified and available in 32A and 63A ratings.
✅ Key Benefits
