The main current circuit uses spring-loaded terminals accepting 2x (0.25... 2.5 mm²) solid or stranded wire, which speeds wiring and resists loosening under vibration compared to screw clamps.
Rated for 10 A maximum in AC-12 duty (resistive loads at line frequency) and 3 kW at 400 V in AC-3 duty (squirrel-cage motors), so it handles small pumps, fans, and conveyors up to about 4 kW at 690 V. For DC switching at 24 V it carries 10 A, dropping to 2 A at 60 V and 0.3 A at 220 V — the inductive DC curve is steep, so verify your load's time constant against the listed points. The magnet coil draws 3.3 W on closing and 3.3 W holding — a constant-grip DC coil that doesn't need a separate economizer circuit. Mechanical life is typical 30 million operations, so it outlasts most machines it will ever control.
The -ZW97 suffix indicates a special version. If your BOM calls for the base 3RT1015-2BB41, confirm the -ZW97 is an acceptable substitute — the functional ratings are identical to the standard catalog part.
Type 1 coordination requires a 35 A gL/gG fuse; Type 2 coordination needs a 20 A gL/gG fuse. That's the short-circuit protection rating for the main contacts — size your branch circuit protection accordingly.
