That range covers everything from standard 30 mA personnel protection up to 5 A for fire protection or equipment protection on large distribution feeders. The time delay is also adjustable: set values of 0, 0.06, 0.15, 0.3, 0.5, 1.0, 2.0, and 3.0 seconds. A 0-second setting gives instantaneous trip; the longer delays allow selectivity with downstream RCDs. The unit includes a pre-alarm indication at 30% of the set residual current, which lets maintenance catch a degrading insulation condition before the RCD trips the load. Infeed can be from top or bottom, which simplifies busbar routing inside the panel. ## Mechanical integration and environment Mounting is by screw fixing — it bolts to the side of the 3VA1 breaker, not DIN-rail. Dimensions are 70 mm deep, 131.8 mm wide, 187 mm high. The unit is sealable for applications requiring tamper-evident metering or compliance lockout. The product status is Active. The 3VA9114-0RS20 is a current-production SENTRON accessory, not a phase-out or NRND line.","metaTitle":"Siemens 3VA9114-0RS20 SENTRON RCD510, 160 A, 4-Pole","metaDescription":"Siemens 3VA9114-0RS20 SENTRON RCD510 residual current device, type A, 160 A, 4-pole, adjustable 0.03-5 A.
