Product Overview

Siemens 3RB3016-1TB0 is a SIRIUS 3RB3 solid-state overload relay designed for motor protection in size S00 contactor assemblies. Its electronic release is adjustable from 4 to 16 A and operates with CLASS 10E tripping behavior.

The device combines overload, phase-failure and asymmetry protection with an internal power supply, one normally closed contact for contactor disconnection and one normally open contact for trip signaling. Manual and automatic reset modes must be reviewed against the machine safety concept.
