Lifecycle status for 3RU2116-0CB1 is current production. No end-of-life notice or last-time-buy date. Mounting is stand-alone installation or direct onto a SIRIUS S00 contactor. Screw terminals for the main circuit accept 2×(0.5…1.5 mm²) or 2×(0.75…2.5 mm²) solid or stranded. The auxiliary switch is integrated, so no separate module is needed for the trip signal. Dimensions are 89 mm height, 45 mm width, 80 mm depth — fits a standard DIN-rail enclosure with room for the contactor below.","metaTitle":"Siemens 3RU2116-0CB1 SIRIUS Thermal Overload Relay, CLASS 10","metaDescription":"Siemens 3RU2116-0CB1 SIRIUS thermal overload relay, CLASS 10, size S00, 690 V rated insulation.

The 3RU2116-0CB1 is the correct overload relay to pair with that contactor, but it is a separate device that mounts directly on the contactor or adjacent on the DIN rail. If the panel was built with only the contactor, you will need to add this relay and wire the motor leads through it."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RU2116-0CB1","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/3RU2116-0CB1 when reusing this data.
