Product Positioning

The 3RT1075-6AM36 is a Siemens SIRIUS 3RT10 series S12 frame large power contactor, designed for direct starting and stopping of large three-phase motors and high-current switching in switchboards. The coil voltage is compatible with 200-220V AC/DC, and it features a robust 3-pole main contact structure, making it suitable for long-term, high-load operation in industrial environments.

Core Product Advantages and Features

S12 large frame, high current carrying capacity

The main circuit AC-1 can reach 430A, and AC-3 is about 400A/200kW, which is sufficient to directly start and stop large motor loads.

200-220V coil voltage

AM coil code corresponds to 200-220V AC/DC, no additional step-down transformer needed.

Built-in 2NO2NC auxiliary contacts

It comes pre-configured with 2 normally open and 2 normally closed auxiliary contacts for easy linkage with control circuits or PLC monitoring.

Bus main circuit terminals

The main circuit uses busbar (BAR) terminals, suitable for direct locking of large cross-section cables or copper busbars.

High mechanical life

Compliant with IEC 60947-4-1 standard, with a mechanical operating life of tens of millions of cycles.
