| Design Of The Product | For motor protection |
Its adjustable overload release covers a range of 1.4 to 2 A, and it carries a CLASS 10 trip class, meaning it will trip within 10 seconds at 7.2× the set current — appropriate for protecting standard induction motors during startup without nuisance tripping on the inrush.
The S00 frame keeps the footprint compact for panel integration. Screw-type terminals on top and bottom accept the main circuit wiring. At 400 V the breaker is rated for 750 W motor power.
CLASS 10 means the overload release will trip within 10 seconds at 7.2× the set current. This suits standard induction motors with moderate startup times — fast enough to protect the motor winding, slow enough to ride through the inrush without nuisance tripping.
The current-dependent overload release adjusts from 1.4 to 2 A. The magnetic short-circuit trip is fixed at 26 A.
This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
Both share the same S00 frame size, DIN rail mounting, and screw terminal arrangement. The key difference is the overload range: this unit adjusts 1.4...2 A, while the 1HA10 covers 5.5...8 A. Panel cutouts and wiring positions are identical, so a swap requires only adjusting the overload setting — no rewiring.
