Rated 16 A \/ 7.5 kW at 400 V (AC-3), the Siemens 3RT2018-1AP02 is a 3-pole SIRIUS 3RT2 contactor, size S00, operated by a 230 V AC, 50\/60 Hz coil. It has 1 NC integrated auxiliary contact, and Siemens rates it at 22 A for resistive (AC-1) loads at 40 \u00b0C. Siemens quotes a typical mechanical life of 30,000,000 operating cycles for this contactor.<\/p>\n
Contactors in pump, fan, conveyor and compressor panels may switch thousands of times a day, and contact wear is the usual reason for replacement. Keeping a spare of the same order number avoids long stoppages.<\/p>\n

The coil voltage is coded in the order number (here 230 V AC, 50\/60 Hz), so check it against your control circuit before ordering.<\/p>\n Frequently asked questions<\/h3>\n |
