The N breaking capacity code places it in the standard-interrupting range for this platform — sized for secondary distribution and large motor control center (MCC) incoming feeds where fault levels stay within the N curve. Drawout mounting means the moving portion withdraws for inspection or swap without breaking the main bus connections; a panel builder planning a switchboard layout accounts for the 560 mm depth behind the door plus the racking mechanism travel.
Dimensions: 560 mm deep × 400 mm wide × 440 mm high. The drawout mechanism requires clearance at the front for the racking handle swing and at the rear for the primary disconnect fingers. Mounting is on a steel chassis frame bolted into the switchgear enclosure — not DIN-rail mountable at this frame size. The 4-pole configuration covers three-phase plus neutral, common for 3200 A main incoming or generator paralleling sections where full neutral isolation is specified.
In a 50 °C ambient — common in non-air-conditioned industrial rooms — the breaker must be derated per Schneider's thermal correction table; the chassis itself does not change, but the trip unit settings and cable sizing must account for the lower headroom. The N breaking capacity code typically corresponds to a short-circuit breaking capacity around 42 kA at 415 VAC (verify the specific trip unit rating for the installation's fault level). This chassis accepts the standard EasyPact NW trip units and auxiliaries; the drawout cradle is pre-wired for the control plug.
