Why Choose the TE Connectivity 1SNA111033R0300 MB10/12.SF Fuse Terminal?
The TE Connectivity 1SNA111033R0300 is a grey MB10/12.SF screw clamp fuse terminal block designed to combine conductor termination and circuit protection within industrial electrical panels. Part of the established ENTRELEC SNA series, it provides a convenient DIN rail-mounted fuse holder for protecting individual control, signalling and power circuits.
The MB10/12.SF incorporates a screwable fuse holder designed for cylindrical 5 × 20 mm and 5 × 25 mm fuses. This integrated arrangement allows a fuse to be positioned directly within the terminal assembly, creating an organised and serviceable installation while allowing straightforward fuse replacement when required.
With a nominal conductor cross-section of 10 mm², an IEC rated current of 10 A and rated voltage of 500 V, the 1SNA111033R0300 is well suited to industrial control and distribution applications. Its 12 mm spacing, screw clamp connections and compatibility with G32 and TH35 DIN rails make it a versatile choice for panel builders and machine manufacturers.

Integrated Fuse Protection for Industrial Control Circuits
Fuse terminal blocks combine electrical connection and overcurrent protection within a compact modular format. By incorporating the fuse holder directly into the terminal assembly, the MB10/12.SF helps reduce separate panel components while keeping protected circuits clearly organised and accessible for inspection and maintenance.
The screwable holder provides convenient access to the cylindrical fuse, while the screw clamp conductor connections provide secure and serviceable wiring. The MB10/12.SF is therefore particularly useful in industrial installations where individual circuits require replaceable fuse protection within a DIN rail terminal assembly.
Typical Applications
- Industrial control panels and switchboards.
- Fused control and auxiliary circuits.
- Machine and factory automation systems.
- PLC and instrumentation wiring.
- Electrical distribution cabinets.
- OEM machinery and production equipment.
