At 24 V DC rated value it switches 10 A; at 230 V AC rated value also 10 A; at 400 V AC rated value 3 A — so it handles control transformer secondaries, PLC outputs, and contactor coils across common line voltages. Width is 45 mm, depth 73 mm, height 58 mm. Coil closing power and holding power are both 4 W DC, so the coil driver sees a steady load. Operating frequency at DC-12 duty reaches 1000 1/h, and at AC up to 10 000 1/h. Pollution degree 3 (conductive pollution) means it's suitable for industrial enclosures where some condensation or dust is present.","metaTitle":"Siemens 3RH2131-1BF40-ZW97 Contactor Relay, S00, 110 V DC, 1","metaDescription":"Siemens 3RH2131-1BF40-ZW97 contactor relay, size S00, 3 NO + 1 NC, 110 V DC coil, 10 A rated at 24 V and 230 V.
