TrustedTM Power Distribution Unit MCB 24V-T8292

GENERAL ASSEMBLY

DESCRIPTION

The dual 5-channel Trusted
MCB 24V is designed for N+1 or 100% redundant 24V
dc power distribution applications. The unit is designed
to be mounted on a standard DIN rail. Monitoring
circuits provide local LED indication of individual MCB
‘trip’ status and a relay contact provides a common
alarm signal output.

Power fed to the Trusted
MCB 24V is sub-distributed via the dual MCBs either
as an N+1 or 100% redundant configuration, via the
fitting (for N+1) or removal of the board mounted link,
LK-N+1.

The standard factory-fitted configuration is N+1.

Each MCB is monitored for open circuit condition and
provides a local on-board LED indication of individual
‘trip’ status (red LED displayed for tripped).

A volt-free relay contact provides the common alarm
output signal (contact open for tripped) for connection
to external alarm monitoring circuits.
