What the 1000 A and H rating mean for your switchgear lineup
The H breaking capacity (typically 65 kA or 85 kA at 415 V, depending on the specific variant) governs fault interruption capability; for a 1000 A frame, H class means it clears high prospective fault currents without upstream fuses in most industrial distribution boards. Drawout mounting lets you rack the chassis out for maintenance or replacement without disturbing the busbars — a standard requirement for main and tie breakers in switchgear where uptime matters.
Dimensions: 445 mm depth, 400 mm width, 440 mm height. The drawout chassis requires a matching cradle and fixed portion in the switchgear cubicle — verify the cutout and racking mechanism against your existing EasyPact NW installation. The 3-pole configuration suits three-phase distribution; the chassis itself is the moving portion that carries the arc chutes and main contacts.
