It snaps onto the starter base via plug-in fixing — no tools, no DIN-rail space wasted. The 10 mm depth keeps the plug flush with the starter body, so it doesn't steal panel depth from the wiring channel. ## Physical fit — dimensions that matter for panel layout At 10 mm deep, 20 mm wide, and 25 mm tall, this plug adds negligible bulk to the starter stack. The plug-in fixing means it engages directly with the starter's PE bus bar — no separate wiring or terminal block needed for the ground bond. Pollution degree 3 rating confirms it's built for industrial enclosures where conductive dust or condensation is present. The environmental range spans -20 to +60°C during operation and -55 to +80°C during storage or transport, matching typical panel ambient conditions. ## Mechanical endurance for vibrating panels Tested to semi-sinusoidal shock at 6 m/s² for 10 ms in three positive and three negative axes, plus vibration resistance from 4 to 500 Hz with 15 mm displacement at low frequencies and 2 m/s² acceleration at higher bands. These ratings cover what a motor starter sees on a conveyor or pump panel. Functional designation per EN 61346-2 and IEC 81346-2 is 'X', the standard code for PE conductors — no ambiguity about its role in the schematic. ## Sourcing and lifecycle status The listed peer MPNs (6ES7193-4CC30-0AA0, 6ED1052-1MD08-0BA1, 6AG1052-2FB08-7BA1) are from different Siemens product families and are not functional substitutes for this PE plug.","metaTitle":"Siemens 3RA6890-0EA SIRIUS PE Extension Plug, 63 A","metaDescription":"Siemens 3RA6890-0EA SIRIUS PE extension plug for motor starters.
