Siemens 3RT1015-1HB41 Industrial AC Contactor

Siemens Sirius 3RT1015-1HB41 is a three-pole AC-3 power contactor in the S00 frame size, engineered to switch three‑phase motors up to 3 kW at 400 V AC using a 24 V DC control coil. It employs three normally open main contacts plus one normally open auxiliary contact, providing both motor switching and a signaling contact in a compact, screw-terminal package. The main terminals and the coil use screw connections, with the coil driven from 24 V DC across A1 and A2. With a rated AC-3 current of 7 A at 400 V, this unit is well suited for motor starter duties in automation panels, conveyors, pumps, fans, and other equipment controlled by PLCs. The 3RT1015-1HB41 belongs to the Sirius 3RT1 family, offering a compact 3-pole design that integrates easily into standard control circuits while delivering reliable switching performance under typical industrial duty. This model reflects Siemens' approach to robust, field-proven motor control components designed for ease of wiring and dependable operation in demanding environments.
