Product Positioning

The 3RW4036-1TB05 is a lower current-rated soft starter in the SIRIUS 3RW40 series S2 frame, with a rated operating voltage extended to 400...600V AC and a built-in thermal resistor input to enhance motor temperature protection.

Core Product Advantages and Features

Thermal resistor input protection

It receives the PTC signal from the motor winding and immediately trips to protect the motor in case of abnormal temperature rise.

Wide voltage level

Rated operating voltage covers up to 600V AC, suitable for field environments with higher voltage power supply.

S2 baseboard simplified design

This model belongs to the lower current rating in the series and is suitable for small to medium power motor applications.

Screw terminal wiring

Using traditional wiring methods, on-site construction connections are easy.
