The 76 mm depth leaves room in shallow enclosures — verify the 70 mm installation depth against your gland plate clearance. Rated for universal current operation (AC/DC), it handles 400 V AC in single- or multi-phase and up to 440 V DC.
Also carries UL1077 recognition for supplementary protection in North American panels.
The overall depth is 76 mm, with an installation depth of 70 mm. The 6 mm difference accounts for the toggle handle projection.
The 5SY5240-7 is a 40 A version of the same 2-pole C-curve SENTRON MCB. Both share the same 36 mm width, 2 MW footprint, and DIN-rail mounting — physical swap is straightforward if the circuit rating permits. The 5SY5220-7 is the 20 A variant; do not substitute unless the load side is rated for 20 A or less.
