The SFRSE7 from CBI-electric is a DIN mount 3-pole 10 kA RCBO that comes in a compact 3-module width. At 54 mm wide, the SFRSE7 fits the existing CBI Advantage distribution board chassis while allowing for 3-pole MCBs to be interchanged with a 3-pole RCBO. The SE7 is DIN mountable for use in enclosures for providing three-phase overload, short circuit and earth leakage protection. The SE7 RCBO range is available in C and D curves from 10–63 A. With the ever-increasing demand not only for RCBO protection but for compact protection solutions, the three-phase RCBO is a suitable addition to the CBI Advantage range of distribution boards and the CBI range of circuit protection devices.
