MRK Series Screw Connection Rail Fused Terminal Blocks
Onka offer great value fully encapsulated DIN rail terminals. The MRK Series includes these 6mm2 fused terminal block which clip direct to standard 35mm DIN rail. They provide basic overcurrent and short circuit protection.
- Larger CSA cables up to 6.0mm2 can be terminated at the fuseholder
- Accepts standard 5 x 20mm fuse, fast lever operation
- Typically used in control panels for distribution of DC power supply
- No need to purchase additional end plates - terminal has an embedded end plate
- Terminals are symmetrical - does not matter which way around they are mounted
- Accepts solid conductors or crimped ferrules - lock into place without tools
- Save time and drive down costs with fast installation and simplified accessories
Suitable for:
- 35 x 7.5mm DIN Rail (Top Hat Rail)
- 35 x 15mm DIN Rail (Top Hat Rail)
- Matches Old Onka Part Number 1322

Frequently Asked Questions
What cable size does this terminal accept?
6mm² solid or ferruled conductors (8AWG UL), 10mm strip length. The fuse rating (6.3A) applies regardless of cable size, since it's fuse-limited rather than conductor-limited.
What fuse does it take?
A standard 5x20mm glass fuse (sold separately) — see our 5x20mm glass fuse range for matching ratings.
Do I need any tools to wire it?
Yes — this is a screw connection terminal (0.8Nm torque), with a 5-stage fuse carrier mechanism to prevent accidental opening.
Is this compatible with my existing Weidmuller or Wago terminals?
It's the same footprint and rating as the Weidmuller WSI 6 (screw connection, like this one) and Wago TopJob S 2202-1911 (push-in connection).
Industry Applications
- Control panel building — larger-gauge fused circuit protection
- DC power distribution — individual circuit protection on heavier supply cables
- OEM machine builders — cost-effective alternative to premium European brands
