The 3RV1011-1FA10-ZW96: This breaker is rated for motor protection with Trip Class 10, meaning it will trip within 10 seconds at a locked-rotor current of 7.2× the thermal setting — fast enough to protect standard induction motors from overheating during a stall.
The 3RV1011-1FA10-ZW96 carries 100 kA breaking capacity at 240 V and 400 V, which means it can safely interrupt a fault current up to 100,000 A at those voltages without welding contacts or cascading failure upstream. For most 400 V industrial distribution this is well above typical available fault currents, giving headroom for selectivity coordination. Backup fuse requirements are specified: at 400 V use gL/gG 50 A; at 500 V and 690 V use gL/gG 35 A. At 240 V no backup fuse is needed, simplifying the bill of materials for lower-voltage panels.
Main circuit terminals are M3 screw-type, accepting 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) solid or stranded conductors. Clearance: 20 mm upward, 20 mm downward, 9 mm sideways, 0 mm forward/backward — plan your wire bends and enclosure depth accordingly.
Environmental range
The wide storage range is typical — the part can sit in a warehouse or truck without damage, but the operating band governs in-panel performance.
