Product details

The MS451-45E: Mounts on DIN rail via the integrated clip — no adapter plate needed. The 3-pole unit occupies roughly 45 mm of rail width. Line-side and load-side terminals accept 16-35 mm² copper conductors. The adjustable dial sets the thermal trip point within the 36-45 A band; a separate magnetic short-circuit element handles the 50 kA interruption. For panel builders, the compact footprint leaves room for additional contactor or relay blocks in the same enclosure.
