TAXNELE TXBD1-63 — DC Miniature Circuit Breaker for Solar PV
DC miniature circuit breaker with special arc extinguishing system and current limiting design, providing overloading and short circuit protection for DC distribution systems and solar photovoltaic installations. Real photovoltaic product — purpose-built for DC solar applications.
Features
- Special DC Arc Extinguishing System — rapid disconnection of fault current in DC distribution
- Current Limiting Design — limits let-through energy to protect downstream equipment
- PC Flame Retardant Housing — thermosetting material that carbonizes rather than burns
- DIN Rail Mounting — standard 35mm DIN rail for easy installation
- Type C Trip Curve — suitable for circuits with moderate inrush currents
