It provides phase failure detection and has a breaking capacity of 100 kA at 400 V AC, dropping to 6 kA at 690 V AC — meaning it can handle heavy fault currents on a standard 400 V distribution system without needing an upstream fuse for most installations. Front IP20 protection keeps live terminals out of accidental contact during panel work. Screw terminals on both main and auxiliary circuits accept 1–2.5 mm² solid or stranded (2x) and 2.5–6 mm² (2x), with AWG 14–10 equivalents for the main contacts. Zero clearance needed at the back or sides for ventilation. RoHS compliance date marked as 01.05.2012. Shock rated at 25g for 11 ms.","metaTitle":"Siemens 3RV1021-1EA10-ZW96 SIRIUS Motor Protection Breaker,","metaDescription":"Siemens SIRIUS 3RV1021-1EA10-ZW96 motor protection circuit breaker, 4 A continuous, Class 10 trip, 100 kA breaking at 400 V.
