Product Positioning

The 3RT2017-1HB41 shares the S00 frame and 24V DC coil design with its sibling, the 1HB42. The coil's operating range is 0.7 to 1.25 times the rated voltage. The main circuit has an AC-3 rated capacity of 12A/5.5kW (400V) and one set of normally open (NO) auxiliary contacts, suitable for use as operating status feedback or start-up interlock signals. Distributor data indicates a net weight of approximately 294 grams, a main circuit insulation voltage of 690V, and an IP20 protection rating. Both the main circuit and control circuit use screw terminals, allowing for direct installation using existing S00 frame distribution panel mounting holes.

Core Product Advantages and Features

Wide operating voltage range

It can engage normally within a voltage range of 0.7 to 1.25 times the rated voltage, and can still operate stably even with a slight drop in power supply voltage.

1 set of normally open auxiliary contacts

It can be used to indicate operating status, or linked with PLC input points and indicator lights.

Full safety certification

It complies with standards such as IEC 60947-4-1 and IEC 60947-5-1, and has obtained certifications from multiple countries including UL, CSA, and KC.

Standard S00 installation specifications

The hole spacing and dimensions of the 3RT20 series S00 frame are used, which makes it easy to directly replace existing distribution panels.
