DC-rated 4-pole MCB for infrastructure and residential panels
The 4-pole construction (4P) means all four poles switch and protect the DC circuit simultaneously, suitable for ungrounded or bipolar DC systems where full isolation is required. Rated for DC operation only, this MCB covers applications in residential buildings and infrastructure — think PV combiner boxes, DC distribution boards, or battery-bank protection where the voltage exceeds typical 72 V DC single-pole limits. The C-curve (10× to 15× In magnetic trip) handles moderate inrush from DC loads like contactor coils or LED drivers without nuisance tripping.
The 5SL5410-7RC occupies 4 modular width units (72 mm) on a standard DIN rail, with a depth of 76 mm and height of 90 mm. Supplementary devices such as shunt trips, auxiliary contacts, or alarm switches can be added via the product extension interface, so a single SKU can be field-adapted for remote tripping or status feedback without replacing the breaker.
