Designed specifically for high-voltage direct current applications, the TOMZN 2-Pole DC Miniature Circuit Breaker provides essential protection for solar PV arrays, battery storage setups, and inverter input lines. Engineered to interrupt high-voltage DC arcs, this specialized breaker ensures safe circuit isolation and shields your renewable energy equipment from overcurrents and short-circuit faults.
Key Features
- High-Voltage DC Protection: Rated for up to 1000V DC operation, making it ideal for string solar panel systems and off-grid battery banks.
- Polarized Dual-Pole Design: Safely interrupts positive and negative lines simultaneously for complete DC circuit isolation during maintenance or system faults.
- 6kA Arc Extinguishing Capacity: Built with specialized internal arc chutes to effectively suppress and extinguish persistent direct-current electrical arcs.
- Multiple Ampere Options: Available in 16A, 20A, 32A, and 63A ratings to fit your specific PV array current requirements.
- Standard DIN-Rail Compatibility: Snaps directly onto 35mm DIN rails inside solar combiner boxes, DB enclosures, and control cabinets.
