Product Positioning

The 3RT1056-2NP36 is a SIRIUS 3RT10 series S6 frame contactor. It uses an electronic wide-range operating coil, can be driven by AC/DC power supplies of 200-277V, and supports direct control of 24VDC PLC signals, simplifying wiring. The prefix 2 indicates that the control circuit uses spring terminals. It has a rated AC-3 rating of 185A and an output of 90kW at 400V, making it suitable for control panels with a high degree of automation.

Core Product Advantages and Features

Electronic wide-range coil

A single 200-277V AC/DC coil covers multiple voltages, reducing the number of spare parts available.

Supports PLC-IN 24VDC direct drive

The coil can be directly driven by the PLC output signal, simplifying the control circuit design.

Spring-loaded terminal design

The prefix 2 in the model number indicates that the control circuit uses spring-loaded terminals, which allow for quick wiring and prevent loosening.

AC-3 rated 185A/90kW

Rated current is 185A and output is 90kW at 400V; it can reach 132kW at 500V.

2NO+2NC auxiliary contacts

Four sets of auxiliary contacts facilitate interlocking control and status feedback wiring.
