Siemens 40EP25AANK is a four-pole SZ1.75 power contactor with a 120/240 V AC coil, designed to switch three-phase loads in control panels and industrial equipment. The unit uses normally open (OPN) main contacts, making it suitable for energizing motors, pumps, and compressors from a standard 120/240 V control circuit. As part of the Siemens 40EP family, it provides compact, reliable switching with the 4P configuration and supports common Siemens accessories within the SZ1.75 size family. This model is commonly used in HVAC, pumping, and automation applications where robust isolation and control of three-phase circuits are required.
