O-PEN Protected MCB-MCCB Boards

17-04-2024

O-PEN® protection now available in a 200A, combined MCB – MCCB boards. As EV chargers increase in power output standard MCB boards cannot supply these larger chargers. The OPMCX board allows fitting 2 x MCCBs as well as MCB’s without the need to use a full size MCCB panelboard.

All boards have a 200A, 4 pole, switch disconnector main isolator, and can accommodate two 3 pole MCCBs up to 160A maximum. The MCB section can be 4, 6 or 8 TP ways up to 63A depending on the board ordered. This section can be fitted with our 3 module 4 pole RCBO’s and MCBs and 2 pole 1 module RCBOs, as well as all our other MCBs and RCBOs.

PEN protection is fitted, switching 3 phases, neutral and the EVC insulated earth bar, giving total disconnection from the supply in the event of a PEN fault. BS 7671, ammendment 2, clause 722.411.4.1 (iii) references: when using this PEN protection earth rods are not required, potentially saving time and money.

The layout of the board has been arranged to assist installation in a feeder piller with the main switch fitted to the top of the panel, allowing easy cabling from an adjacent service head. Outgoing cables are bottom exit for cabling through a trench.

The width is 600mm, narrower than a full MCCB board, helping to maximise the space within the feeder pillar. Options for surge arrestors and metering are available.

This new OPMCX range of combined MCB – MCCB boards are designed to compliment typical feeder pillar and service head arrangements. MCCBs allow chargers up to 100kW and the MCB section can be fitted with 3 mod 4 pole, Type A RCBOs.
