DC12~1200V 10~63A 1P/2P/3P/4P Miniature Circuit Breaker STL7-PV

1. CNST miniature circuit breakers are specifically designed for PV and solar applications
1P/2P/3P/4P DC miniature circuit breakers provide reliable overload/short-circuit protection and isolation for photovoltaic systems rated at 12-1200V DC, 10A/16A/20A/25A/32A/40A/50A/63A, with a breaking capacity up(Icu) to 6kA.
2. Flame-retardant housing and silver contacts
Features a flame-retardant, UV-resistant PA housing, silver alloy contacts, and a high-capacity pure copper coil to ensure excellent arc extinction performance and reliable overcurrent/short-circuit protection.
3. Non-Polarity and Thermomagnetic Trip
Precision thermomagnetic trip technology combined with enhanced DC arc extinction capability ensures safe and reliable disconnection of PV circuits. Non-polarity wiring supports reverse wiring applications, reducing cable and power losses.
4. STL7-PV Applications
Zhongnong circuit breakers are suitable for solar panel arrays, solar charge controllers, inverters, RVs, grid-connected/off-grid systems, residential rooftops, and other PV DC systems; also compatible with AC systems.
