Product Positioning

The Siemens 3RT2036-1NB34 contactor is a SIRIUS 3RT2 series S2 size, 3-pole contactor with an AC-3 rated current of 51A and a power output of 22kW (400V), and a maximum rated operating voltage of 690V. The Siemens 3RT2036-1NB34 features a wide control voltage range of 20-33V AC/DC. With the addition of an auxiliary contact module, it is configured with 2NO+2NC contacts, providing more complete circuit monitoring signals. Both the main circuit and auxiliary circuit use screw terminals.

Core Product Advantages and Features
2NO+2NC complete auxiliary contact
Adding an auxiliary contact module provides 2 normally open and 2 normally closed contacts, providing more complete monitoring feedback than a single contact.
Wide voltage range 20-33V AC/DC
The control voltage covers 20-33V AC/DC, and one device can be used to handle various control circuit voltages.
AC-3 rated 51A, 22kW
The 3-pole main circuit has a rated current of 51A and a power of 22kW under 400V AC-3, with a maximum operating voltage of 690V.
Screw terminal mounting design
Both the main circuit and auxiliary circuit use screw terminals, ensuring high consistency between maintenance and panel wiring.
