Ground fault detection is not included, so if that's required, you'd add an external GFI module upstream.
Where it fits — panel and mounting
Width is 45 mm, depth 97 mm, height 97 mm — a compact footprint that leaves room for adjacent devices. Clearance requirements: 50 mm above and below, 30 mm to the side, and zero clearance forward or backward — so you can tuck it against a backplate or door without derating. Main circuit connection uses ring cable lugs with M3 screws — typical for this class of motor protection breaker. The auxiliary contact block (if fitted) shares the same mounting rail and clips on the side.
The gL/gG fuse coordination values tell you what upstream fuse to use for selective coordination: at 400 V, a 25 A gL/gG fuse; at 500 V, a 32 A gL/gG; at 690 V, back to 25 A gL/gG. This keeps the breaker tripping on a fault without blowing the upstream fuse, so only the faulted branch drops out.
