SIRIUS 3RT2327-1BB40 — 24 VDC coil, Size S0 frame
The Siemens 3RT2327-1BB40 is a SIRIUS-brand contactor in the Size S0 frame, with a 24 VDC magnet coil and screw-type terminals. Rated switching capacity is 10 A at both 24 VDC and 230 VAC — the DC rating at 24 V is the same as the AC-1 resistive load at 230 V, so this contactor handles DC loads up to 10 A without derating for the coil voltage.
Panel fit and clearances
Dimensions are 85 mm high, 60 mm wide, and 107 mm deep. The coil pick-up voltage is 0.8× rated (19.2 VDC minimum), and the drop-out is 1.1× rated (26.4 VDC maximum), giving a clean switching margin on a nominal 24 VDC bus.
Wiring and auxiliary contacts
Main contact wiring accepts 1 to 10 mm² stranded or solid conductors. An auxiliary switch is included as standard. Arcing time is 10 ms at DC. The coil operates with a DC pick-up time of 15 to 18 ms.
