Why Choose the TE Connectivity 1SNA115700R0500 MA2.5/5.SNBT1 Disconnect Terminal Block?
The TE Connectivity 1SNA115700R0500 MA2.5/5.SNBT1 is a compact screw-clamp disconnect terminal block with blade and integrated test sockets from the ENTRELEC SNA series, designed for signal circuits in industrial control panels, instrumentation and automation systems. Its disconnect blade allows an individual circuit to be opened without removing the connected conductors, simplifying testing, commissioning and maintenance.
The MA2.5/5.SNBT1 combines proven screw-terminal connection technology with two built-in 2 mm test sockets. The disconnect blade can be operated by hand or with a screwdriver, providing convenient circuit isolation and test access while maintaining secure conductor termination. Its matching profile with MA2.5/5 feed-through terminals also supports aligned marking and consistent panel construction.
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 1SNA115700R0500 is well suited to industrial signal and control wiring. Its narrow 5 mm width helps maximise DIN rail capacity in high-density control cabinets.
