Why Choose the TE Connectivity MB10/22.SF Fuse Terminal Block 1SNA116302R2300?
The TE Connectivity MB10/22.SF 1SNA116302R2300 is a heavy-duty screw clamp fuse terminal block designed to combine secure conductor termination with convenient overcurrent protection in industrial control panels, switchboards and machinery. Part of the established ENTRELEC SNA terminal block range, it is specifically designed to accommodate 10.3 × 38 mm cartridge fuses.
The MB10/22.SF provides a practical method of incorporating fuse protection directly into a DIN rail terminal assembly. Its 22 mm spacing provides room for the cartridge fuse holder while robust screw-clamp connections ensure secure conductor retention. The fuse is accessible for inspection and replacement without requiring the surrounding terminal assembly to be dismantled.
Rated at 30 A and 800 V, the 1SNA116302R2300 has a rated cross-section of 6 mm² and accepts flexible conductors from 0.5–6 mm² and rigid conductors from 0.5–10 mm². Its grey polyamide housing, IP10 terminal protection and wide -55 to +110 °C operating temperature range make it suitable for demanding industrial installations.

Reliable Fuse Protection for Industrial Circuits
Fuse terminal blocks provide individual circuit protection while keeping wiring and protective devices together in an organised DIN rail assembly. The TE Connectivity MB10/22.SF accepts a standard 10.3 × 38 mm cartridge fuse, allowing a damaged or operated fuse to be replaced without disturbing the connected conductors.
Its high 30 A current rating, robust screw-clamp connections and conductor capacity up to 10 mm² rigid make the 1SNA116302R2300 suitable for industrial circuits requiring greater current capability than smaller signal-level fuse terminals. Compatibility with several common DIN rail formats also simplifies integration into new and existing control-panel designs.
Typical Applications
- Industrial control panels and switchboards.
- Machine and equipment power circuits.
- PLC and automation cabinets.
- Protected auxiliary electrical circuits.
- Power distribution and control systems.
- Process control installations.
- OEM machinery and electrical panel construction.
