DC Circuit Breakers, Disconnect Switch & Fuses
DC miniature circuit breakers Ex9BP are designed for direct current, thanks to their polarity independency, especially for photovoltaic aplications where some failure can change the polarity of the voltage.
1 and 2-pole versions to 250 and 500 V DC are suitable for general DC applications and small PV systems, 3 and 4-pole breakers with rated voltage to 750 and 1000 V DC mainly for bigger photovoltaic applications.
Devices are offered with rated current up to 63 A, rated breaking capacity 6kA (Ex9BP-N) or 10kA (Ex9BP-H), tripping characteristic C and K.
The Circuit Breakers are Present between
- Solar Panel & MPPT Solar Regulator
Industrial fuses are designed to protect installations and equipment against overload and short-circuit currents on low voltage electrical
circuits. NH fuses are rated at AC690V - 50kA, DC250V - 100kA.
NH fuse switch disconnectors are used on low voltage electrical systems that require high protection against shortcircuit while securing on load circuit disconnection and isolation.
