24 Vdc Power Supply Module

An external 24 Vdc power supply is required for installations with communication networks, regardless

of the type of trip unit.

On installations without communication networks, the power supply is available as an option for

Micrologic 5/6 to:

•

modify settings when the circuit breaker is open (OFF position)

•

display measurements when the current flowing through the circuit breaker is low

•

maintain the display of the cause of tripping

To determine power requirements of devices, see page 90.
