It mounts directly onto a contactor (contactor mounting). Three poles for the main current circuit, so it covers a standard three-phase motor. The auxiliary circuit has one normally-closed contact — that's your trip alarm or feedback to the PLC. The ATEX approval (PTB 06 ATEX 3001 Ex II (2) GD) means it's certified for use in potentially explosive gas and dust atmospheres — the (2) indicates it's associated apparatus that can be installed in the safe area but protects the motor in the hazardous zone. That's a big deal for chemical, grain, or paint-line applications where a standard thermal overload won't fly. Solid-state construction means no bimetallic strip to drift with age or ambient temperature swings. The relay measures true motor current via internal CTs and applies an I²t curve. It's also shock-rated to 15g / 11 ms and operates in 100 % relative humidity, so it's fine in washdown areas or on vibrating machinery — just keep the ambient between -25 °C and +60 °C during operation. The relay is 45 mm wide, 64 mm tall, and 73 mm deep. Mounting position is any, so you can lay it sideways in a shallow enclosure if needed.","metaTitle":"Siemens 3RB2016-1ND0 SIRIUS Solid-State Overload Relay, CLAS","metaDescription":"Siemens 3RB2016-1ND0 SIRIUS solid-state overload relay, CLASS 10E, 3 poles, 45 mm wide, ATEX Ex II (2) GD.

The 3RT1016-1AR11 is a SIRIUS contactor, so the mechanical fit and wiring footprint are compatible — same 45 mm width, same screw-type main terminals. The auxiliary circuit on the 3RB uses spring-loaded terminals instead of screw terminals, so the control wiring may need a different termination tool, but the terminal locations align.
