Dimensions are 45 mm width, 97 mm height, and 96 mm depth, with zero clearance required at the back or sides — useful when packing multiple units on a DIN rail in a crowded enclosure. Front protection class is IP20; the housing is finger-safe for touch protection against electrical shock, which matters for panel access without full de-energization during troubleshooting. Lifecycle stage is current production — this part is still in active manufacture per the manufacturer's status. Shock resistance is 25 g for 11 ms. RoHS compliance date is 01.05.2012; the part is free of substances prohibited under that directive as of that date. Main circuit terminals accept solid or stranded conductors: 2x (1 to 2.5 mm²) and 2x (2.5 to 6 mm²), with AWG equivalents of 2x (14 to 10). Finely stranded with core end processing uses the same ranges. Power dissipation at AC in hot operating state is 9.25 W total, or 3.1 W per pole — a figure to check against enclosure thermal budgets when grouping multiple breakers.","metaTitle":"Siemens 3RV1421-1JA10-ZX95 SIRIUS Circuit Breaker, 10 A, Cla","metaDescription":"Siemens 3RV1421-1JA10-ZX95 SIRIUS circuit breaker for transformer protection. 10 A continuous, Class 10 trip, 100 kA breaking at 400 V.
