It protects a 3-phase + neutral outgoing circuit against overloads, short-circuits, and earth leakage in a single 54 mm wide package. Breaking capacity is 6 kA Icn at 400/415 V AC, 50/60 Hz, which covers most commercial and light industrial distribution boards where the prospective fault current stays below that level. The limitation class 3 rating means it lets through less energy during a fault, helping downstream selectivity.
Clip-on mounting to standard 35 mm DIN rail. The 54 mm width occupies 6 modules of 9 mm pitch. Depth is 77.2 mm, height 112 mm — fits standard distribution enclosures without crowding the door or busbar shroud. Tightening torque is 2.5 N.m. Wire strip length is 11 mm for bottom connections. Neutral is on the left, and the toggle provides local ON/OFF indication. Padlockable with a Ø 4 mm padlock for lockout/tagout during maintenance.
Designed and certified to AS/NZS 61009.1, the Australia/New Zealand standard for RCBOs. Suitable for TN earthing systems. Tropicalisation level 2 indicates treatment against humidity and corrosion for warm, damp environments. Relative humidity tolerance of 95% at 55 °C covers most non-condensing indoor installations.
