Introduction
The matt:eB60 is a single phase Voltage Optimisation unit.
The unit reduces the incoming supply voltage by 18v (i.e.: a 240v supply
would be reduced to 222v). It is designed to be connected in series with the
incoming supply installed between the main electricity meter for the dwelling,
and the consumer unit.
The matt:eB60 has short circuit, overload and thermal protection built in.
Rated at 14kW, the unit is suitable for the majority of domestic and light
commercial / retail installations.

Electrical Connections
The unit is supplied with a 63 Amp miniature circuit breaker that provides overload
and short circuit protection for the unit.
The transformer is fitted with an embedded thermal switch. Should the temperature
of the transformer increase beyond acceptable levels the thermal switch will operate
and automatically shut off the supply to the transformer by ‘tripping’ the incoming
MCB (CP1). Once the transformer temperature has returned to an acceptable level
the thermal switch will reset and the MCB can be closed.
The user wiring connections are indicated in the diagrams below:
On completion of installation the tightness of all electrical connections should
be checked.
