The Siemens 3RF3340-1AA26 is a 1-pole SIRIUS 3RF33 solid-state contactor rated for 40 A in AC-1 duty at 40 °C, with a switching voltage range of 48-600 V and a control supply of 110-230 V AC, terminated via screw terminals. The AC-1 rating covers resistive loads — heaters, ovens, lighting banks — where inrush is negligible. For motor or inductive loads, derate per the AC-3 curve; the 40 A AC-1 figure does not carry over to motor switching.
