The overload release is thermal, using a bimetallic strip heated by the motor current. Ambient temperature compensation is active from -40 to +60 °C, so the trip curve stays accurate across the panel's internal temperature range. ## Panel fit and wiring — size S00 with spring-loaded terminals It mounts in any position and is designed for stand-alone installation, not ganged to a contactor. The auxiliary switch is integrated — no separate add-on block needed for the N/C alarm contact. Power dissipation per pole is 1.6 W — at full load the relay dissipates about 4.8 W total across three poles. Budget this into the panel thermal calculation, especially in a sealed enclosure. ## Auxiliary contact ratings — what voltage matches your control circuit These are the make/break capacities for the alarm circuit — match the contact rating to your PLC input or control relay coil draw. The note for message \"Tripped\" indicates this auxiliary contact changes state when the overload relay trips — it's the N/C (normally closed) contact that opens on overload, commonly wired into a safety chain or PLC digital input. ## Lifecycle and sourcing — active production, quoted to order The relay carries a substance prohibitance date of 10/01/2009, confirming RoHS compliance per EU Directive 2002/95/EC.","metaTitle":"Siemens 3RU2116-0AC1 SIRIUS Overload Relay, CLASS 10, S00","metaDescription":"Siemens 3RU2116-0AC1 SIRIUS thermal overload relay, size S00, CLASS 10 trip class.
