  • Description

The Schneider Electric LV454444 is a regulated switch-mode external power supply that converts 200-240 V AC into a stable 24 V DC output at 1 A, built to feed the MicroLogic control and trip units on MasterPact MTZ, NT, NW, ComPact NSX and PowerPact breakers whenever an independent 24 V DC source is needed for communication.

Selection Notes

LV454444 is the single-output 1 A / 24 W version of this external power supply — size the DIN-rail branch around that 24 W ceiling when a MicroLogic unit also has to drive communication modules on the same circuit. The regulated 24 V DC output and -25...70 degC operating range suit switchboard enclosures where ambient heating from adjacent breakers is a factor. Choose this module only when the panel design already runs a 200-240 V AC feed to the compartment; the MicroLogic unit otherwise takes its power from the breaker itself.
