The coil holds across the full voltage band; the 0.8 initial and 1.1 full-scale multipliers bracket the operating range. The S2 frame measures 114 mm high, 75 mm wide, and 130 mm deep. The screw-type coil terminals accept 2x (0.5-1.5 mm²) and 2x (0.75-2.5 mm²) solid or stranded wire. ## Switching Performance and Environment Mechanical life is typical 10,000,000 operations. The auxiliary switch is included, with switching capacity at various voltages: 10 A at 24 V, 10 A at 230 V, 3 A at 400 V, among others.","metaTitle":"Siemens SIRIUS 3RT2337-1NB30-ZX95 Contactor, S2 Size, 20-33","metaDescription":"Siemens SIRIUS 3RT2337-1NB30-ZX95 contactor, S2 frame, 20-33 V AC/DC coil, screw terminals, auxiliary switch included.
