Kromschroder Power module LM400 WF3O0E0- 74966105

The Kromschroder LM400 WF3O0E0- power module (SKU 74966105) is a spare part designed for use with Kromschroder LMV3 and LMV5 burner control systems. It supplies electrical power to the control unit and connected actuators such as ignition transformers, gas valves, fan motors, or damper actuators. The module participates in the burner start-up, operation, and shutdown sequences by providing energised outputs when required. This item is manufactured in Germany.

Replacement modules of this kind are selected by matching the input and output voltage and current ratings to the original unit. The physical form factor and connector arrangement must match the existing mounting. Because the power module is integral to the safety logic of the burner control, the replacement must have identical functional behaviour—such as timed power sequencing and fault signalling—as the original. Before fitting, verify the electrical ratings marked on the original unit against the replacement, and confirm the module is approved for the specific burner control model.
