Rated for 5.5 kW at 690 V AC and 4.5 kW at 500 V AC, it handles the usual 400 V three-phase motor circuit comfortably. Mechanical life is typical 30 million operations, so it's not a short-life commodity part.
Width is 45 mm, height 57.5 mm, depth 114 mm — the S00 envelope. Side-by-side mounting is allowed with zero gap, so you can pack a row of these on a DIN rail without wasting panel width. Main circuit terminals are screw-type, accepting solid or stranded wire: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or max 2x (0.75 to 4 mm²). AWG equivalents are 2x (20 to 16), 2x (18 to 14), and single 12 AWG. Strip length is standard for a screw clamp — no push-in convenience here, but the terminal is the same across the S00 line, so your panel builders already know the torque spec.
These are the manufacturer's specified values for the main circuit — use them to size the branch protection without over-fusing.
