Its 24 V rated coil pulls in at 85% of rated value and drops out at 185%, giving a clean pickup and dropout margin for PLC or relay outputs. Clearance requirements are 10 mm upwards, forwards, and downwards, with 6 mm at the sides — tight enough for dense layouts if you keep the arcing zone (10 to 15 ms) clear of grounded metal. The DC switching ratings tell you exactly what this contactor can break without welding contacts: 10 A at 24 V, 2 A at 48 V and 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, and 3 A at 400 V. These are not continuous carry ratings — they are the make/break capability for DC inductive loads, where the arc is harder to extinguish than AC. If your load draws more than these numbers at the given voltage, step up to a larger frame. Wire terminations are screw-type, accepting solid or stranded conductors from 0.5 to 4 mm², and up to two conductors per clamp (2x 0.5-1.5 mm², 2x 0.75-2.5 mm², or 2x 4 mm²). This is useful when you need to loop through the contactor to feed a downstream device without a separate terminal block.","metaTitle":"Siemens 3RT2015-1MB41-0KT0 SIRIUS Coupling Contactor, 24 VDC","metaDescription":"Siemens SIRIUS coupling contactor 3RT2015-1MB41-0KT0, 24 VDC coil, size S00, screw terminals, 10 A at 24 VDC.
