Why Choose the TE Connectivity 1SNA199105R2200 ML10/13.SN Disconnect Terminal Block?
The TE Connectivity 1SNA199105R2200, manufacturer type ML10/13.SN and commonly described as an M10/13.SN fuse holder, is a black and blue screw-clamp disconnect terminal block from the Entrelec SNA range. It is designed for signal circuits requiring a clearly accessible means of disconnecting the electrical path for testing, commissioning and maintenance.
The terminal uses a lever-operated disconnect mechanism together with robust screw-terminal conductor connections. It provides one circuit, two poles and two positions in a single-level format, with a 10 mm² nominal wire size and conductor capacities extending to 16 mm² for a rigid stranded conductor at the screw clamp.
With an 800 V IEC voltage rating, 16 A IEC current rating and 8 kV impulse withstand rating, the 1SNA199105R2200 is suitable for demanding industrial signal and control installations. Its 13 mm width, Polyamide 6.6 housing and compatibility with G32, TH35-7.5 and TH35-15 rails make it a versatile component for modular control-panel assemblies.

Lever-Operated Isolation for Signal and Control Circuits
The ML10/13.SN incorporates a mechanical lever disconnect that allows the conductive path through the terminal to be opened without removing the connected field wiring. This provides technicians with an accessible isolation point for circuit testing, commissioning, troubleshooting and maintenance while preserving the organised layout of the terminal assembly.
Secure screw-terminal connections accommodate flexible conductors up to 10 mm² and rigid stranded conductors up to 16 mm². Combined with the 800 V IEC rating, 8 kV impulse withstand capability and compatibility with three common industrial rail profiles, the terminal provides a robust connection and isolation solution for industrial control and signal wiring.
Typical Applications
- Industrial electrical control panels.
- Signal circuit isolation.
- Automation and PLC cabinets.
- Electrical testing and commissioning systems.
- Machine control wiring.
- Instrumentation and monitoring circuits.
- DIN rail terminal assemblies.
- OEM machinery and industrial electrical equipment.
