Main terminals are screw-type, accepting 2x (1 to 2.5 mm²) solid or stranded, up to 2x 10 mm² maximum. Auxiliary terminals accept 2x (0.5 to 1.5 mm²) solid, up to 2x (0.75 to 4 mm²). This is a standard wiring range for S0 contactors — no special crimping tools needed. The 3RT1026-1AG20-ZX95 carries a mechanical life of 10 million operations typical, which is the standard for this frame size. Electrical life depends on the switching duty — AC-4 at 15.5 A will wear the contacts faster than AC-3 at the same current. Short-circuit coordination: with Type 2 assignment (no welding), the required fuse is gL/gG 35 A. With Type 1 coordination (welding allowed but no fire risk), the fuse can be gL/gG 100 A. This matters when sizing upstream protection for a motor branch circuit. Front protection is IP20 (finger-safe), terminal area is IP00 (no protection). Side-by-side mounting is permitted with zero clearance, saving panel width — the 45 mm width stacks tightly. ## Auxiliary contact block This variant ships with zero factory-fitted auxiliary contacts (instantaneous contact count: 0). The S0 frame accepts add-on auxiliary contact blocks that snap onto the front or side. If your circuit needs N.O. or N.C. feedback, budget for a separate block. When adding auxiliaries, the contact ratings are: 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, and 0.3 A at 220 V DC. These are the switching limits for the auxiliary circuit — don't expect the same current at higher voltages.","metaTitle":"Siemens 3RT1026-1AG20-ZX95 SIRIUS Power Contactor, S0, 110V","metaDescription":"Siemens SIRIUS 3RT1026-1AG20-ZX95 power contactor, size S0, 110V 50/60Hz coil.
