What the Class 10 and Size S00 ratings mean for fit
The 3RU2116-0GB0-ZX95: For high-inertia loads like centrifuges or crushers, a Class 20 or 30 relay would be needed to avoid nuisance trips during start-up. It mounts directly onto the matching Siemens contactor (no DIN rail required), saving panel space and reducing wiring — the power connections pass through the contactor, not the relay.
Auxiliary contact signals the trip — what the note means
The note 'for message Tripped' indicates that the integrated auxiliary contact changes state when the relay trips, providing a discrete signal to a PLC input, indicator lamp, or annunciator. This is the 'trip alarm' contact — separate from the contactor coil circuit, so the control system knows the motor has been stopped by an overload, not by a normal stop command. Confirm the control voltage and load type (resistive vs. inductive) against these ratings to ensure reliable switching.
Temperature compensation and environmental range
The relay is temperature-compensated from -40 to +60 °C, meaning the trip curve stays accurate across that ambient range without manual adjustment. This matters for outdoor enclosures, unheated pump houses, or near hot machinery where ambient temperature varies. The relay can be stored in unconditioned warehouses and installed in most industrial environments without derating for temperature alone.
As an active-production Siemens SIRIUS part, the 3RU2116-0GB0-ZX95 is sourced through authorized distribution channels. Pricing and lead time are confirmed at RFQ against the BOM quantity — no minimum order restriction for this standard catalog item.
