The ENW13210 is a 3-pole EasyPact NW circuit breaker from Schneider Electric, rated 800 A at 40 °C and carrying a 66 kA Icu at 220...440 V AC 50/60 Hz per IEC 60947-2. Category B utilization means it's designed for distribution duty with selective coordination, not just cable protection. Rated insulation voltage (Ui) is 1000 V AC, and impulse withstand (Uimp) is 12 kV, so it's comfortable on 400/480 V systems with decent margin for switching surges. Short-time withstand (Icw) is 50 kA for 1 second — that's the current it can carry without damage during a delayed trip coordination sequence, which is the spec you need when setting up a selective tripping scheme with downstream breakers. That's the standard for unsealed switchgear in factory environments — no special derating needed for typical panel conditions.
Fixed mount on a rail base plate, rear-connected. Dimensions are 276 mm wide × 301 mm high × 196 mm deep. Connection pitch is 70 mm without spreader, which is the standard for this frame size — busbar drilling patterns and cable lug spacing should match that centerline.
