Siemens 3RT1526-1AK60 Contactor

Siemens 3RT1526-1AK60 Contactor is a four-pole power contactor designed for AC-3 motor control duty, rated for 11 kW at 400 V and up to 25 A, with four main contacts and an auxiliary contact arrangement of 2 normally open and 2 normally closed contacts. This size S0 device uses screw-terminal connections and, for the coil, is 120 V AC for 60 Hz operation (110 V AC, 50 Hz variants are supported within the same family). The 3RT1526-1AK60 belongs to Siemens' Sirius 3RT family, offering a compact footprint for panel mounting and reliable switching for three-phase loads such as motors in conveyors, pumps, fans, and other equipment in industrial automation. For installation, ensure the coil supply frequency matches the coil rating to maintain the stated performance; the 11 kW/400 V rating aligns with a 25 A nominal current, enabling efficient motor start-up while providing interlock and signaling capability via its auxiliary contacts. This model is a genuine Siemens part, compatible with standard 3RT accessories and mounting hardware to ensure straightforward integration into existing control architectures.
