Frequently asked questions
What is the adjustable overload range?
The current-dependent overload release adjusts from 7 to 10 A. The magnetic short-circuit release is fixed at 130 A.
Will the 3RV1011-1JA15-ZI45 drop into a panel built for the 3RV1011-1HA10?
Both are size S00 with the same 45 mm width and screw/snap-on DIN-rail mounting, so the physical footprint and rail position are identical. The difference is the overload range: the 1HA10 adjusts 5.5 to 8 A, while this 1JA15 adjusts 7 to 10 A. If the motor FLA falls within 7–10 A, it is a direct mechanical swap without rewiring.
