Why Choose the TE Connectivity 1SNA115699R2000 MA2.5/5.SNB Switch Terminal?
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.
