Siemens 3RH2140-1BB40 — SIRIUS Auxiliary Contactor, Size S00
The Siemens 3RH2140-1BB40 is a SIRIUS auxiliary contactor in size S00, carrying 4 normally open instantaneous contacts. Clearance to adjacent devices: 10 mm upward, forward, and downward; 6 mm at the side.
Switching Capability Across Voltages
The 3RH2140-1BB40 switches the following currents at rated voltages: 10 A at 24 V AC/DC, 10 A at 230 V AC, 4.7 A at 60 V, 3 A at 110 V, 1.2 A at 220 V, 3 A at 400 V, 0.5 A at 440 V, 2 A at 500 V, 0.26 A at 600 V, and 1 A at 690 V. These are the contact ratings for the auxiliary circuit — match the load voltage to the column that covers your control transformer or PLC output.
Relative humidity minimum 10 %. RoHS compliance date of 10/01/2009 is on record — the part meets the substance prohibitions effective from that date.
