It handles 160 A rated current across 4 poles, with adjustable residual current sensitivity from 0.03 A up to 5 A and a configurable time delay from 0 to 3000 ms — meaning you can tune it to avoid nuisance tripping on inrush or leakage from downstream filters. The module is sealable, carries an IP40 front protection rating, and mounts via screw fixing. Infeed can be top or bottom, which simplifies busbar routing in a crowded panel. The 160 A rated current matches the main breaker's frame; this RCD is not a standalone device — it connects via cable connection to the basic breaker, so the panel design must already include a 3VM series molded-case breaker. The adjustable residual current range (0.03, 0.05, 0.1, 0.3, 0.5, 1, 3, 5 A) covers both personnel protection (30 mA) and equipment protection (up to 5 A), and the selectable RCD or monitoring mode lets you use it purely as a ground-fault monitor without tripping the load — useful for pre-fault alarming in continuous-process lines. The pre-alarm indication at 30% of the set residual current gives early warning before a trip event, which a maintenance planner can use to schedule a line shutdown rather than react to an unplanned outage. The electrical trip indicator confirms the device has operated; there is no communication-based indicator, so this is a local-only signal. ## Integration note Physical footprint: 70 mm deep, 131.8 mm wide, 187 mm tall. The 70 mm depth is shallower than many standalone RCDs, which helps in shallow enclosures. Screw fixing means it mounts directly to the panel backplate or a mounting plate — no DIN rail required, but also no tool-less snap-on. Plan for a screwdriver and torque driver during assembly. The IP40 front is fine for a closed panel; if the front is exposed to washdown or dust, you'll need an additional enclosure.","metaTitle":"Siemens 3VM9114-0RS20 SENTRON RCD210, 4-pole, 160 A, adjusta","metaDescription":"Siemens SENTRON 3VM9114-0RS20 RCD210 residual current device, type A, 4-pole, 160 A, adjustable 0.03–5 A, 0–3000 ms delay.
