The main contacts are rated for 20...12 A (the range suggests a 12 A continuous rating in AC-3 duty, typical for a Size S00 frame switching a 4 kW motor at 400 V). Switching frequency limits vary by duty: 1 000 cycles/hour for AC-1 resistive loads, 750 for AC-2 and AC-3 motor loads, and 250 for AC-4 plugging/inching. The AC-3e rating also caps at 750. If your application requires frequent jogging or reversing, the AC-4 limit governs — plan your cycle count accordingly. The contactor accepts solid or stranded wire from 0.5 to 4 mm², or 2x 0.5 to 4 mm² for paralleled feeds. Operating time is 7...13 ms make, arcing time 10...15 ms break — tight enough for most coordination schemes with standard motor circuit protectors. The 3RT2018-2AB02-ZX95 measures 70 mm high, 45 mm wide, and 73 mm deep.","metaTitle":"Siemens SIRIUS 3RT2018-2AB02-ZX95 Power Contactor, Size S00,","metaDescription":"Siemens SIRIUS 3RT2018-2AB02-ZX95 power contactor, Size S00, 45 mm width, spring-type coil terminals.
