Its 480 V 60 Hz coil matches North American control voltage standards. Three normally-open main contacts handle the power circuit, with screw-type terminals accepting solid and stranded wire from 0.5 to 4 mm² (or 2x 10 mm² max) and AWG 16 to 8. Side-by-side mounting is allowed with zero gap, saving panel space — a 6 mm clearance to grounded parts is required on the sides.
That means it can switch a 15 HP motor at 480 V or an 18.5 kW motor at 690 V without welding the contacts on inrush. For purely resistive loads (AC-12), the maximum operating current is 10 A. The auxiliary contact block handles 10 A at 24 V, 6 A at 230 V, and 3 A at 400 V — these ratings are for the built-in or add-on auxiliary contacts, not the main poles. Type 1 coordination allows a 100 A gL/gG fuse upstream; Type 2 coordination (no contactor damage after a fault) requires a 35 A gL/gG fuse.
Environmental and Installation Limits
Maximum altitude 2 000 m without derating. The 60 Hz coil tolerance is 0.8 to 1.1 times rated voltage. Dimensions: 85 mm height, 45 mm width, 91 mm depth. The depth is the critical dimension for shallow enclosures — verify your gland plate clearance if back-mounting.
No official successor exists because it is the active design. If you are holding a legacy panel with an older S0 contactor, this 3RT1026-1AV60-0UA0 is the direct drop-in replacement for the same frame size and coil voltage. Verify the auxiliary contact configuration if your existing unit has a different stack.
