Plug-in Portable Test Unit (PTU)

Specially designed for reliable testing of the MCR and HSISC
protection systems on each phase, by means of tertiary
injection. The test unit is also used to prove both overcurrent
and earth fault pick-up levels. Can also be employed to
test for tripping in order to verify efficient microprocessor
operation. The test unit incorporates a set of rechargeable
batteries and includes a charger unit as standard.

Auxiliary Power Unit (APU)

Available to be fi tted within the circuit breaker cubicle, an APU
ensures that MPRO receives independent and continuous
power at all times. The APU accepts any input supply voltage
within 380VAC, 110V, 220V AC/DC. Maximum input current
is 0.5 A. 1m length cable (twisted pair) should be used to
connect auxiliary supply and MPRO protection relay.
