Mounts via the quick-assembly system (DIN rail) in any position — no derating needed for horizontal or inverted orientation. The 3-pole body occupies 3 width units (54 mm) on the rail, with a depth of 76 mm and an installation depth of 70 mm behind the panel surface. IP20 with connected conductors is standard for enclosed distribution boards; the sealable option lets the panel builder lock the toggle position to prevent unauthorized switching during commissioning or maintenance.
Energy limiting class 3 means this MCB limits the let-through energy (I²t) to a low level, which improves downstream device protection and aids selective coordination with upstream breakers. The 10 kA SCCR at 400 V AC covers most industrial panel fault levels; for higher available fault currents, verify the upstream device's let-through curve against the MCB's withstand. Combined top and bottom terminals allow loop-through wiring without extra busbars — a time-saver on the panel wireman's bench.
