Tunnel terminals top and bottom simplify wiring — strip, insert, torque, done.
Snaps onto standard DIN rail. The 70 mm installation depth is shallow enough to clear most gland plates and back-panel wiring ducts — no need to rework the enclosure depth if swapping from another 4-pole MCB with similar depth. Four poles in a single module width; tunnel terminals at both ends keep the wiring plane clean.
