Siemens 3RT2016-1AR61 AC Coil Contactor 400V/440V 1NO

Product Positioning

The Siemens SIRIUS 3RT2016-1AR61 features a 400V (50Hz)/440V (60Hz) AC coil, making it a rare specification in the S00 series of power contactors that can directly drive the coil with a 400V three-phase power supply. It is suitable for switchboards or machine-side control boxes where the control circuit itself is 400V and no additional step-down transformer is required. The main contact AC-3 is rated at 9A/4kW/400V and includes one set of normally open auxiliary contacts.

Core Product Advantages and Features

400V/440V Dual-Frequency Coil

The coil can operate at 400V at 50Hz and 440V at 60Hz. The operating voltage range is 0.8~1.1 times the rated value at 50Hz and 0.85~1.1 times at 60Hz. The holding power is only 4.4~4.8 VA, with low heat generation and power consumption.

AC-3 9A/4kW main contact

The three-pole main contacts are rated at 9A according to IEC 60947-4-1 AC-3 category, and can control a 400V/4kW three-phase motor load, with a maximum operating frequency of 750 times per hour.

1NO auxiliary contact and high contact reliability

It has a built-in set of normally open instantaneous auxiliary contacts, with AC-15 rated at 10A@230V, 3A@400V, 2A@500V, and 1A@690V. The contact failure rate is as low as only 1 in 100 million operations (under 17V and 1mA conditions).

Multiple international certifications and classification body accreditations

In addition to general CE standards, it has obtained regional certifications such as CSA, UL, CCC, KC, and EAC, and has passed classification approvals from ship classification organizations such as ABS, BV, DNV, and LR, making it suitable for export equipment and marine switchboards.
