Noark 2 Pole 40A 500VDC 6ka

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 PV 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.

• Non-polarized, suitable for PV applications
• Tested according to IEC / EN 60947-2
• Rated short circuit breaking capacity I_cu 10 kA
• Rated operating voltage U_e 250 V DC per pole
• Width 1 up to 4 modules
• Tripping characteristics C, K
• Rated current up to 63 A
