The AC-12 maximum operating current of 10 A covers resistive loads like heater banks. These are the numbers that govern the real selection, not a single headline current. Termination is screw-type on the main circuit, accepting solid conductors from 2x 0.5 mm² up to max 2x 4 mm², and stranded from 2x 1 mm² up to max 2x 10 mm². That covers most panel wiring up to the 35 A fuse required for Type 2 coordination (gL/gG) or the 100 A fuse for Type 1. Side-by-side mounting is allowed (zero gap), which saves rail space when multiple contactors share a common bus. Electrical life will be lower and depends on the switching duty (AC-2 vs AC-4) and the actual current switched. At 45 mm wide, 85 mm tall, and 91 mm deep, the S0 envelope fits a standard 4-module DIN-rail pitch. The 91 mm depth is the dimension from the mounting rail to the furthest projection — check that against your enclosure depth, especially if a door-mounted operator or busbar shroud sits behind the contactor. Screw terminals on the main circuit; auxiliary contact blocks (not included) snap onto the front or side without increasing the width beyond the S0 frame.","metaTitle":"Siemens 3RT1026-1AU60 SIRIUS Power Contactor, S0, 3-Pole, 11","metaDescription":"Siemens SIRIUS 3RT1026-1AU60 power contactor, size S0, 3 NO main contacts.
