The TE Connectivity 1SNA115699R2000 MA2.5/5.SNB is a compact screw-clamp disconnect switch terminal block from the ENTRELEC SNA series, designed for convenient circuit isolation in industrial control panels, instrumentation and automation systems. Its integrated blade disconnect provides a simple method of opening an individual signal circuit without removing the connected conductors.
The MA2.5/5.SNB combines proven screw-terminal connection technology with a short orange disconnect blade for clear visual identification of the switching point. The blade can be operated to isolate the circuit during commissioning, testing, maintenance and fault finding, while the terminal's compact 5 mm width helps maximise available DIN rail space.
With an IEC voltage rating of 320 V, an IEC current rating of 10 A and a nominal conductor size of 2.5 mm², the 1SNA115699R2000 is well suited to industrial signal circuits. It accepts flexible conductors from 0.5–2.5 mm² and rigid stranded conductors from 0.5–4 mm², providing flexibility for a wide range of panel wiring applications.
Disconnect switch terminal blocks allow individual electrical circuits to be opened during commissioning, testing and maintenance without disturbing permanent field wiring. The MA2.5/5.SNB uses a blade disconnect mechanism together with secure screw-clamp connections, providing straightforward isolation of signal circuits while keeping conductors firmly terminated.
Its narrow 5 mm profile makes the MA2.5/5.SNB particularly useful in high-density control cabinets where DIN rail space is limited. The Polyamide 6.6 housing, wide operating temperature range and compatibility with common DIN rail profiles provide a durable connection and switching solution for machinery, instrumentation and industrial automation equipment.
