Product Positioning

The 3RT1054-3AP36 is a Siemens SIRIUS 3RT10 series S6 frame large three-pole power contactor. Its biggest difference from the common 6AP36 specification lies in the terminal type: the main circuit uses box-type terminals, while the auxiliary and control circuits use spring-loaded (screwless) terminals, making wiring faster and less prone to loosening. Electrical specifications and the 220-240V AC/DC coil are consistent with the same series, making it suitable for production line environments that prioritize rapid installation.

Core Product Advantages and Features

Spring-loaded control terminal

The auxiliary and control circuits are screwless and can be connected simply by plugging them in, making installation faster.

Main circuit box-type terminal

The main circuit adopts a box-type terminal design, which has a large contact area and stable conductivity.

AC-3 rated 115A/55kW

It can handle the main circuit control of large three-phase motors and heavy-duty equipment at 400V.

220-240V AC/DC universal coil

The same product can be supplied with either AC or DC control power, simplifying the selection and material preparation process.

Built-in 2NO+2NC auxiliary contacts

It provides interlocking and monitoring loops for easy integration with PLCs or control panels.

SIRIUS Modular Platform

It can be combined with overload protection and surge suppression modules to expand its applications.
