ICP 2-Pole 40A Contactor for ZAEB025CHA1 — 24V Coil | Ships Today

Overview

This genuine OEM 2-pole, 40-amp definite-purpose contactor (part #1066570) is the electrical switch that energizes the compressor and condenser fan in your ICP ZAEB025CHA1 system. A 24-volt coil pulls the contacts closed when the thermostat calls, passing line voltage to the high-amperage loads. Over time the contacts pit, burn, and weld from constant arcing. A failing contactor causes hard starts, chattering, a compressor that won't engage, or — when welded shut — an outdoor unit that never shuts off. Pitted or burnt contacts and a coil that won't pull in are the classic failure signs.
