Motor protection circuit breaker, size S00 — Trip Class 10, 100 kA SCCR
The interrupting rating is 100 kA at 240 V, 400 V, 500 V, and 690 V AC — that's a single symmetrical rating across the common industrial voltage bands, so no coordination derating is needed when the panel feeds multiple voltage levels. The screw-type terminals on the main circuit accept 2×(0.75–2.5 mm²) or a single 4 mm² conductor — sized for standard motor branch-circuit wiring up to the S00 frame limit.
The 3RV2011-0FA10-ZX95 measures 45 mm wide × 97 mm high × 97 mm deep. Clearance requirements: 50 mm upwards and downwards, 30 mm to the side, 0 mm forwards and backwards. The zero forward clearance means the breaker can be mounted directly against the enclosure back wall or a busbar shield without additional spacing. The -20 °C floor matters for unheated enclosures in cold climates — the thermal trip curve stays compensated down to that point.
