TE Connectivity 1SNA116290R2300 MB10/22.S2 is a screw-clamp fuse terminal block for 10.3 x 38 mm cylindrical fuses, rated at 30 A and 800 V for industrial circuit protection and panel wiring.
£27.68
The TE Connectivity 1SNA116290R2300, also identified as MB10/22.S2, is a robust screw-clamp fuse terminal block from the ENTRELEC SNA range. Designed for industrial control panels, machinery and electrical distribution systems, it combines secure conductor termination with an integrated fuse-holder function for circuit monitoring and protection.
The MB10/22.S2 is designed for 10.3 × 38 mm cylindrical fuses and uses a plug-in fuse-holder arrangement for convenient access during inspection and maintenance. Screw-clamp connections provide dependable conductor retention, making the terminal suitable for demanding industrial installations where circuits require both organised termination and individual fuse protection.
With a rated current of 30 A and rated voltage of 800 V, the 1SNA116290R2300 provides substantial electrical capability in a DIN rail-mounted format. It accepts fine-stranded conductors from 0.5–6 mm² and rigid conductors up to 10 mm², while compatibility with G32 and TH 35 rails supports flexible control-panel installation.
Fuse terminal blocks combine electrical termination and overcurrent protection within a modular panel assembly. By locating the fuse directly at the terminal level, individual circuits can be protected while remaining accessible for inspection, troubleshooting and maintenance.
The MB10/22.S2 uses a plug-in holder for 10.3 × 38 mm fuses, helping simplify fuse access while its screw-clamp terminals maintain dependable conductor connections. This combination makes it well suited to machinery, automation and electrical distribution applications requiring robust circuit protection.
