Siemens Industrial Controls 3RB3016-1NB0 Relay 321042-401 For applications requiring thermal expansionThe Siemens SIRIUS 3RB3016 1NB0 is a high performance solid state overload relay engineered for precise protection of three phase induction motors. Designed for direct mounting to Siemens S00 size contactors, such as the 3RT2015 through 3RT2018 series, this electronic unit provides a wide 0. 32 to 1. 25 Amp current range with a 1: 4 setting ratio. Unlike traditional thermal relays, this solid state solution utilizes integrated current transformers to
