Non-polarized Circuit Breakers Ex9BP

Photovoltaic DC Components

Non-polarized Circuit Breakers Ex9BP

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.

Breakers can be combined with wide range of accessories identical with circuit breakers Ex9B including auxiliary and signal contacts, shunt trip release and undervoltage release. All accessories are mounted to device from the left side.

• Non-polarized, suitable for photovoltaic aplications

• Tested according to IEC / EN 60947-2

• Rated operating voltage Ue 250 V DC per pole

• Width 1 up to 4 modules

• Tripping characteristics K

• Rated current up to 63 A
