Siemens 3RT2016-1AD02 42V AC Coil Contactor 1NC AC-3 9A/4kW

Product Positioning

For safety reasons, some machines or control panels may use a low voltage of 42V as the coil control power supply. The Siemens 3RT2016-1AD02 is a SIRIUS 3RT2 series S00 size contactor designed for such applications. It has a coil rated at 42V AC and includes one set of normally closed auxiliary contacts. The main circuit maintains the AC-3 9A/4kW (400V) specification. Kenxin Motors provides in-stock information and selection assistance for this low-voltage coil version.

Core Product Advantages and Features

42V low voltage coil

It meets the safety requirements for control voltage in some production lines, reducing the risk of electric shock at the operating end.

Normally closed auxiliary contact

One set of normally closed (NC) contacts, suitable for power failure alarm, interlocking or safety circuit designs.

AC-3 9A/4kW main circuit

It shares the same main contact rating as the 3RT2016 model in the same series, meeting the switching requirements of small three-phase motors.
