SP-0331A Contactor Economizing Module

The SP-0331A and SP-0332A Contactor Economizing Modules are designed to optimize the performance and lifespan of electrical contactors by reducing holding voltage after coil engagement. These compact, surface-mounted modules deliver a full inrush voltage to ensure reliable contactor pull-in, then automatically reduce voltage to minimize heat buildup, energy consumption, and wear.
