It provides a central readout for power parameters and breaker status across a multi-breaker assembly, with an IP65-rated front face for panel-door mounting in fixed switchboards inside enclosed rooms. The 96 x 96 mm cutout (standard 96 mm square) matches the common panel-meter footprint — it drops into the same DIN 43700 hole as a digital meter or process indicator, so no custom punching. Depth of 56 mm leaves clearance behind the door for wiring and the RJ45 connector. The rear of the unit is not sealed; the IP rating applies to the front face only. ## Communication and power budget One Fast Ethernet interface (100 Mbit/s) with auto-MDI/X and serial gateway function means it connects directly to a plant network without a crossover cable or external media converter. Up to 8 active TCP/IP connections are supported, enough for multiple SCADA or BMS clients polling simultaneously.","metaTitle":"Siemens 3VA9977-0TD10 SENTRON DSP800 Display, IP65 Front","metaDescription":"Siemens SENTRON DSP800 display accessory for 3VA breakers.
