At 25 A per pole, this covers a 5.5 kW three-phase motor at 400 V or a 6 kW single-phase load at 230 V. For industrial panels with higher fault current, the 10 kA-rated sibling (5SL4363-7) would be the pick. At 36 mm wide (2 MW units) and 76 mm deep, it fits standard DIN-rail enclosures.
The sealable design allows lockout/tagout provisions for isolation procedures. Power loss per pole at rated current in hot state is 2.2 W — at 2 poles, expect about 4.4 W total dissipation inside the enclosure.
No — the 5SL4363-7 is 3-pole and 54 mm wide (3 MW units), while the 5SL6225-7MB is 2-pole and 36 mm wide (2 MW). They share the same 76 mm depth and mounting position, but the pole count and width differ, so a panel rewire or different DIN-rail allocation is needed.
