Product Positioning

The 3RT2016-1HB41 belongs to the Siemens SIRIUS S00 miniature power contactor series. The coil is 24V DC, and the operating voltage range is 0.7 to 1.25 times the rated value, adapting to fluctuations in the control power supply voltage. The auxiliary contacts are fixed with one set of normally open (1NO) contacts, a factory-standard configuration for easy direct connection in interlocking or starting circuits as a feedback signal. The main circuit maintains an AC-3 9A, 400V/4kW switching capability. The 3-pole main contacts can directly drive small three-phase motors, solenoid valves, or heating circuits. The housing uses the smallest S00 size in the SIRIUS series, suitable for space-constrained control boxes or machine tool installations.

Core Product Advantages and Features
24V DC coil, wide operating range
The coil can operate normally within a range of 0.7–1.25 times the rated voltage, adapting to fluctuations in the control power supply voltage.
Fixed 1NO auxiliary contact
One set of normally open auxiliary contacts is provided for feedback or interlocking. The factory-set design does not allow for the addition of auxiliary modules.
AC-3 9A/4kW main circuit
The 3-pole main contacts can directly switch 400V/9A three-phase loads, conforming to IEC 60947-5-1 standard.
S00 standard casing
The frame measures 45×58×73mm and supports both 35mm DIN rail and screw mounting.
