CLASS 10 trip and the "Tripped" message
The 3RU2116-1DC0-ZW97: That's the standard speed for general-purpose motor starting where the start-up transient doesn't exceed a few seconds. The note "for message 'Tripped'" on this variant means the auxiliary contact configuration is wired to signal a trip condition back to the PLC or annunciator, rather than directly dropping out the contactor coil.
S00 frame mounts direct to contactor
Size S00 frame — 45 mm wide, 87 mm tall, 70 mm deep — mounts directly onto the matching SIRIUS contactor via the fastening method listed as "contactor mounting." No DIN rail bracket needed; the relay clips onto the contactor's front face, saving one DIN rail position per motor branch. No screw torque to verify — push the stripped wire in and the cage clamps it. The screwdriver shaft diameter is 3 mm with a 3.0 x 0.5 mm tip for the release slot if you need to open the clamp.
Thermal design and ambient compensation
The overload release is thermal — a bimetallic strip bends with heat from the motor current. Temperature compensation from -40 to +60 °C keeps the trip curve accurate across the panel's ambient range, so a hot panel doesn't cause nuisance tripping. Power dissipation per pole is 1.9 W at rated current. For a three-pole relay that's 5.7 W total — negligible for panel thermal budgeting, but worth noting if the enclosure is sealed and densely packed. Mounting position is any orientation.
Active production — sourced per RFQ
Sourced through authorized distribution channels against your BOM quantity. MTTF with high demand rate is 2,280 years — essentially a fit-and-forget component in the motor branch circuit. The relay is designed for the full service life of the panel.
