It draws a maximum of 0.09 A from the supply and dissipates 2.2 VA, so the power budget impact is negligible in any panel that already hosts the breakers it monitors. The front face carries an IP65 rating per IEC 60529, meaning the display surface and bezel withstand washdown spray — suitable for food-and-bev lines, pharmaceutical suites, or any environment where a hose-down is part of the cleaning cycle. The 96 x 96 mm cutout and 56 mm depth match the standard panel-meter footprint. The single Fast Ethernet interface (100 Mbit/s, RJ45, auto-MDI/X) with serial gateway function and support for up to eight active connections means it can talk to a PLC or SCADA over Modbus TCP while also bridging to a serial device on the breaker string — no separate gateway module needed. Supply voltage connects via screw-type terminals; the communication link uses a removable/pluggable RJ45 connector, so the display can be swapped without pulling the Ethernet cable through the gland plate. Overvoltage category I and operating resource protection class III (per IEC 61558) confirm this is a SELV device — it expects to be fed from a limited-energy source, not direct mains.","metaTitle":"Siemens 3VA9987-0TD10 SENTRON DSP800 Display, IP65 Front","metaDescription":"Siemens SENTRON DSP800 display accessory for 3VA breakers.
