Why Choose the TE Connectivity 1SNA116304R2500 MB10/22.SN Disconnect Terminal Block?
The TE Connectivity 1SNA116304R2500 MB10/22.SN is a heavy-duty screw-clamp neutral disconnect terminal block from the ENTRELEC SNA series, designed for industrial control panels, electrical distribution equipment and automation systems. Although sometimes listed as a fuse-holder terminal, the MB10/22.SN is specifically the disconnect version, providing a convenient means of isolating neutral circuits without removing the connected conductors.
The MB10/22.SN uses a hand-operated disconnect lever that allows fast, tool-free circuit isolation during commissioning, testing and maintenance. Its profile matches the complementary MB10/22.SF fuse terminal, making it particularly useful for alternating fuse and neutral disconnect circuits where a neat, consistent terminal arrangement is required.
With an 800 V rated voltage, 30 A rated current and 6 mm² rated cross-section, the 1SNA116304R2500 provides robust performance for demanding industrial installations. It accepts flexible conductors from 0.5–6 mm² and rigid conductors from 0.5–10 mm², while compatibility with G32, TH35-7.5 and TH35-15 DIN rails supports flexible panel integration.

- Flame-retardant UL94 V-0 polyamide insulation.
Reliable Neutral Isolation for Industrial Panels
Neutral disconnect terminals provide a convenient means of isolating individual circuits during commissioning, electrical testing and maintenance without disturbing permanent wiring. The MB10/22.SN combines a hand-operated disconnect lever with robust screw-clamp connections, allowing quick isolation while keeping incoming and outgoing conductors securely terminated.
The MB10/22.SN shares its profile with the MB10/22.SF fuse terminal block, making alternating fused and neutral disconnect circuits easier to arrange and wire. Its 30 A rating, 800 V capability and broad conductor range make the 1SNA116304R2500 particularly suitable for industrial machinery, distribution switchgear and automation cabinets where reliable and accessible circuit isolation is required.
Typical Applications
- Industrial control and automation panels.
- Neutral circuit isolation and disconnection.
- Alternating fuse and neutral disconnect assemblies.
- Electrical distribution and switchgear.
- Machine building and process automation.
- OEM industrial electrical cabinets.
