Size S00 frame, 45 mm wide, 57.5 mm tall, 111 mm deep. Screw and snap-on mounting onto DIN rail; IP20 on the front. Coil is 48 V DC, closing and holding power both 3.2 W. That means the coil draw is constant — no AC hum, but the DC supply must deliver 67 mA steady-state. Surge voltage resistance rated 6 kV per IEC 60947-1; pollution degree 3 for industrial environments. Contact reliability: one incorrect switching operation per 100 million cycles at 17 V, 1 mA — suitable for low-level signal switching in PLC I/O or safety circuits. Wire capacity: 2x (0.5…1.5 mm²), 2x (0.75…2.5 mm²), 2x 4 mm² solid; AWG equivalents 2x (20…16), 2x (18…14), 1x 12. That covers most panel wiring up to 4 mm² without ferrules. Shock resistance 10g / 5 ms and 5g / 10 ms — fine for industrial machinery but not for high-vibration mobile equipment. That gives flexibility in tight enclosures.","metaTitle":"Siemens 3RH1326-1XW40-0AB2 SIRIUS Auxiliary Contactor, 48 V","metaDescription":"Siemens SIRIUS 3RH1326-1XW40-0AB2 auxiliary contactor, 48 V DC coil, 2 NO contacts, 10 A at 24 V.
