The Siemens SENTRON 5SP4380-6 is a 3-pole miniature circuit breaker with B tripping characteristic, rated 80 A and 10 kA breaking capacity at 400 V AC per EN 60898. Mounts on DIN rail or screw fixing, any position, with tunnel terminals top and bottom for solid or stranded conductors.
The 81 mm width and 90 mm height are standard for this SENTRON 5SP series — no surprises when laying out a multi-way distribution board.
10 kA at 400 V AC per EN 60898, which is the standard for branch-circuit MCBs in residential and light commercial distribution boards.
B-curve — trips between 3 and 5 times rated current, suited for resistive and general-purpose loads where inrush is moderate.
