Only 3 poles wide (54mm), this compact RCBO is perfect for replacing 3 pole MCBs in many switchboard upgrades, and can also be used on 3-phase-3-wire circuits (eg. motor without neutral), 2-phase / split phase 240v cooker with L1/L2 input, etc.

Neutral pole is 'solid' (not switched) and fed by a 900mm long tail (a spare bootlace end crimp is supplied). Neutral is not required for test button to operate, as test circuit powered from terminals L3 and L5. (For dual tarriff HWS, wire: L1 = Offpeak Feed, L3 = N, L5 = Peak Feed, do not use N terminal)

Fits Voltex WSBS and C66 range. Fits SBS range and SBF-12/18 way switchboards, when mounted with the terminal bars uppermost. (Will NOT fit into SC-4 surface cover.)

Note: This product differs from the Voltex Uniline family of products:- overall size (110mm height), lever position and wiring orientation is different.

If DIN Rail mounting alongside Uniline RCBOs the wiring orientation is opposite. (Line/supply is from the TOP, load connections at the bottom- additional clearance required), and the lever doesn't align horizontally. (Lever is slightly lower position compared to Uniline)

If chassis mounting alongside Uniline RCBOs the lever position becomes opposite due to the different wiring orientation.
