It's an electronic overload release with CLASS 20E trip characteristics — meaning it'll let a motor draw six times rated current for about 20 seconds before tripping, which is the standard curve for standard-start induction motors driving pumps, fans, or conveyors. Mounts directly to a contactor — no DIN rail needed. The S00 frame size keeps it compact at 45 mm wide, 79 mm tall, and 73 mm deep. Terminals accept 1x (0.5 to 4 mm²) or 2x (0.5 to 2.5 mm²) solid or stranded wire. Screw terminals on the main circuit, Pozidriv PZ2 driver required. ## Signaling and Auxiliary Contacts The integrated auxiliary switch provides a dedicated signaling contact for the \"tripped\" message. Contact ratings: 2 A at 24 V, 4 A at 120 V, 3 A at 230 V, and 0.3 A at 125 V. That covers direct connection to a PLC input or a pilot light without an interposing relay in most cases. The signaling contact has its own shock rating — 9g / 11 ms in the tripped position, slightly lower than the main body's 15g / 11 ms, so keep that in mind for high-vibration environments.","metaTitle":"Siemens 3RB3016-2TB0 SIRIUS Solid-State Overload Relay, CLAS","metaDescription":"Siemens 3RB3016-2TB0 SIRIUS solid-state overload relay, CLASS 20E, rated 16 A thermal current at 690 V.

The 3RB3016-2TB0's electronic design offers tighter trip accuracy and temperature compensation. They share the same contactor mounting footprint, so a panel designed for 3RU2116-1FC1 can accept the 3RB3016-2TB0 without rewiring, but verify the trip class and current setting range match your motor protection requirements."},{"question":"What does the note 'for message tripped' mean on 3RB3016-2TB0?","answer":"It means the integrated auxiliary switch provides a dedicated signaling contact that changes state when the overload relay trips, sending a 'tripped' message — typically wired to a PLC input or alarm light."},{"question":"What are the key specifications of 3RB3016-2TB0?","answer":"It's a CLASS 20E electronic overload relay rated 16 A thermal current at 690 V, size S00, with contactor mounting.
