It mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 60715, and the mounting position allows ±180° rotation on a vertical surface plus ±22.5° tilt forward/backward — useful when fitting into tight panel layouts where the rail isn't perfectly vertical. The screw-type terminals on both main contacts and the magnet coil accept solid or stranded wire from 1 to 10 mm², with double-wire capacity for 2×(0.5…1.5 mm²) or 2×(0.75…2.5 mm²). ## Duty Cycle and Switching Frequency Maximum switching rates are duty-dependent: 1,000 operations per hour in AC-1 (resistive loads), 750/h in AC-2 and AC-3 (motor starting/running), 750/h in AC-3e, and 250/h in AC-4 (plugging/inching). The built-in auxiliary switch handles 10 A at 24 V, 2 A at 48/60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, 3 A at 400 V, and 0.6 A at 440 V — covering common control voltages across 24 VDC to 440 VAC. ## Environmental and Installation Dimensions are 85 mm height, 45 mm width, 97 mm depth — the 97 mm depth is the dimension to watch when planning gland-plate clearance or door clearance in shallow enclosures.","metaTitle":"Siemens 3RT2027-1AP00-ZW96 SIRIUS Power Contactor, S0, 27 A","metaDescription":"Siemens SIRIUS 3RT2027-1AP00-ZW96 power contactor, size S0, 27 A rated operational current at 480 V AC-3.
