The 100 kA breaking capacity holds across the entire voltage range from 240 V to 690 V AC (–), so it interrupts a hard fault without cascading upstream in a panel with a 100 kA available fault current. ## Mounting and wiring — DIN-rail snap-on with spring-clamp terminations The 45 mm width takes one standard modular device slot — panel layout stays tight. Main and auxiliary circuits both terminate through spring-loaded terminals, accepting 2x (0.25…2.5 mm²) solid or 2x (0.25…1.5 mm²) finely stranded with ferrules. No screw torque to verify, no re-tightening on thermal cycling. The 90 mm height and 81 mm depth leave clearance behind a 120 mm deep enclosure door.","metaTitle":"Siemens 3RV1011-0JA20-ZX95 SIRIUS Motor Protection CB, 1 A,","metaDescription":"Siemens 3RV1011-0JA20-ZX95 SIRIUS motor protection circuit breaker, 1 A rated current, Class 10 trip, 100 kA breaking capacity at 400 V.

The difference is the continuous current rating: the -0GA10 is rated at a different pickup point. Verify your motor FLA against the -0GA10's rating before substituting; the -0JA20-ZX95 at 1 A sits at the low end of the family."},{"question":"Will 3RV1011-0JA20-ZX95 drop into a panel specified for 3RV1011-0GA10 without rewiring?","answer":"Yes, the 45 mm width and DIN-rail snap-on mounting are identical across the 3RV10 frame. Both use spring-loaded terminals with the same wire range. No panel re-drilling or terminal rework needed — just verify the current rating matches your motor."},{"question":"What compliance documentation does Siemens provide for this part?","answer":"RoHS and REACH compliance is documented with a substance prohibition date of 01.01.2013.
