Rated 7 A \/ 3 kW at 400 V (AC-3), the Siemens 3RT2015-1AF01 is a 3-pole SIRIUS 3RT2 contactor, size S00, operated by a 110 V AC, 50\/60 Hz coil. It has 1 NO integrated auxiliary contact, and Siemens rates it at 18 A for resistive (AC-1) loads at 40 \u00b0C. Per the Siemens data sheet the coil picks up within 9 … 35 ms and drops out within 4 … 15 ms.<\/p>\n
In a direct-on-line or star-delta starter the contactor does the actual switching, while the overload relay or motor starter protector provides protection. A worn contactor shows burnt contacts, humming or chattering, and failure to pull in.<\/p>\n
