Overview
About this product
MRK screw-connection rail terminal blocks connect field and internal wiring on a standard 35 mm DIN rail. The conductor is clamped under a screw against a serrated current bar for a secure, vibration-resistant connection.
Both sides of the block are closed, so no separate end plate is needed. Blocks can be bridged in groups with comb or screw top bridges, and identified by colour coding, Dekafix or tape markers.
Features

Construction
Protected connection area
Both sides of an MRK block are closed — one a fitted moulded cover across the connection area, the other a solid grey face. No separate end plate is needed at the end of a group, and the screw clamp is covered rather than left open to the panel.
