It occupies one pole plus neutral (1P+N) and switches the neutral conductor. Breaking capacity is rated at 4.5 kA per EN 60898 for domestic-style installation and 15 kA per IEC 60947-2 for industrial distribution boards. The higher IEC figure gives the panel designer headroom for fault-current coordination downstream of a larger upstream breaker. This is a current-production part.
DIN-rail footprint and panel integration
At 36 mm wide (2 modular units), 90 mm tall, and 77 mm deep, the 5SU1353-7KK13 snaps onto standard DIN rail and requires 70 mm installation depth behind the panel surface. Mounting position is unrestricted. Supply can enter from either top or bottom, which simplifies bus-bar routing in crowded enclosures. IP20 rating applies once installed in a distribution board with connected conductors.
