The TE Connectivity MB10/22.SFL 1SNA116303R2400 is a robust screw clamp fuse terminal block designed to combine secure conductor termination with convenient circuit protection in industrial control panels, machinery and power distribution systems. Part of the established ENTRELEC SNA screw terminal range, this grey terminal block is designed for 10.3 × 38 mm cartridge fuses.
The MB10/22.SFL provides a practical way to integrate individual fuse protection directly into a DIN rail terminal assembly. Its plug-in fuse holder enables convenient access to the fuse for inspection and replacement, while robust screw-clamp connections provide secure termination of incoming and outgoing conductors. The fuse itself is not supplied with the terminal block.
With a rated current of 30 A and rated voltage of 800 V, the 1SNA116303R2400 is suitable for demanding industrial electrical circuits. It has a rated cross-section of 6 mm², accepts flexible conductors from 0.5–6 mm² and rigid conductors from 0.5–10 mm², and supports G32 and TH35 DIN rail mounting.
Fuse terminal blocks provide an organised way to protect individual circuits while keeping termination and overcurrent protection together on the DIN rail. The TE Connectivity MB10/22.SFL accommodates a 10.3 × 38 mm cartridge fuse, allowing the protective device to be accessed conveniently without disturbing the connected conductors.
Its 30 A current rating, 800 V voltage rating and screw-clamp conductor capacity up to 10 mm² rigid make the 1SNA116303R2400 suitable for industrial control and distribution circuits. Compatibility with G32 and TH35 rails also enables straightforward integration into new and existing electrical panels.
