The 24 V DC coil picks up at 85 % of rated voltage (20.4 V) and drops out at 185 % (44.4 V) — the wide dropout margin keeps it latched through brief sags but releases cleanly on a sustained undervoltage. ## Switching capability and duty cycle Switching frequency depends on load category: 1 000 operations/hour at AC-1 (resistive), 750/h at AC-2 and AC-3 (motor starting/running), and 250/h at AC-4 (plugging/inching). For DC loads, the 24 V DC rating is the one that governs — the 48 V and 60 V ratings drop to 2 A, and at 400 V DC it is 3 A. The contactor is rated for 30 million mechanical operations typical, so it outlasts most panel cycles.","metaTitle":"Siemens 3RT2015-2VB42 SIRIUS Coupling Contactor, 24 VDC, Siz","metaDescription":"Siemens 3RT2015-2VB42 SIRIUS coupling contactor, 24 VDC coil, size S00, 10 A at 24 V DC, spring-type terminals, DIN rail mount.

However, the terminal type differs — spring-clamp vs screw — so if the panel wiring uses ferrules or ring terminals, the spring-clamp may require a different strip length or ferrule size."},{"question":"Where can I buy 3RT2015-2VB42 and how is it quoted?","answer":"Sourced through the authorized Siemens distribution channel.
