Connections for M-PRO 40
Location Terminal Function
PAMM A1
PAMM A2
OUTPUT 4, normally open volt free contact: Operates when the REF (or SEF) element trips
the ACB. This is used to trip an upstream HV breaker.
PAMM A3
PAMM A4
OUTPUT 3, normally open volt free contact: Used to control shunt trip to open the ACB via
serial link.
PAMM A5
PAMM A6
OUTPUT 2, normally open volt free contact: Load monitoring output will indicate that pre-trip
warn or load shedding is active.
PAMM A7
PAMM A8
OUTPUT 1, normally open volt free contact: Used to control closing coil, facilitating closure
of ACB via serial link.

PAMM A3
PAMM A4
OUTPUT 3, normally open volt free contact: Operates when M-Pro has opened the ACB
due to a trip condition.
PAMM A5
PAMM A6
OUTPUT 2, normally open volt free contact: Load monitoring output operates if pre-trip
alarm or load shedding limits are exceeded.
PAMM A7
PAMM A8
OUTPUT 1, normally closed volt free contact, opens under the following conditions:
Microprocessor malfunction, primary contact maintenance alarm or a digital input is active.
