Product details

The Siemens 3RB3016-2SB0 is a solid-state overload relay from the SIRIUS product brand, designed for motor protection in size S00 frame. It mounts directly on a contactor and provides an electronic overload release with a Class 20E trip curve, rated for 12 A continuous thermal current at up to 690 V AC-3e. The integrated auxiliary switch includes a signaling contact that operates on a trip condition (labeled "for message tripped").

Fastened by contactor mounting, the relay occupies 45 mm width, 79 mm height, and 73 mm depth. Screw-type terminals accept 1x 0.5-4 mm² or 2x 0.5-2.5 mm² solid or stranded wire. Vibration resistance: 1-6 Hz, 15 mm; 6-500 Hz, 20 m/s². Shock resistance 15g/11 ms (9g/11 ms for signaling contact in tripped position).

Frequently asked questions

What does the note 'for message tripped' refer to?

That note describes the integrated auxiliary switch’s signaling contact which changes state when the relay trips, providing a remote indication.

Does the 3RB3016-2SB0 have RoHS compliance?

The part carries a substance prohibitance date of 2009, indicating it meets substance restrictions consistent with RoHS directives.
