Why Choose the TE Connectivity 1SNA115530R1200 MA2.5/5.D1.1 Double-Deck Terminal Block?
The TE Connectivity 1SNA115530R1200 MA2.5/5.D1.1 is a compact double-deck screw-clamp feed-through terminal block from the ENTRELEC SNA series, designed for high-density signal and control wiring in industrial electrical panels. Its two-level construction provides four poles within a housing just 5 mm wide, helping maximise available DIN rail space while maintaining reliable conductor connections.
The MA2.5/5.D1.1 features vertical interconnection between its two decks, allowing a common electrical potential to be distributed across connection points without requiring additional external bridging. Proven screw-clamp termination provides secure conductor retention, while the grey Polyamide 6.6 housing offers robust insulation for industrial control, automation and instrumentation installations.
With an IEC voltage rating of 630 V, an IEC current rating of 24 A and a nominal conductor size of 2.5 mm², the 1SNA115530R1200 combines useful electrical capacity with a space-saving double-deck format. It accepts flexible conductors from 0.22–2.5 mm² and rigid stranded conductors from 0.2–4 mm².

Space-Efficient Wiring for Industrial Control Panels
Double-deck terminal blocks provide two connection levels within the rail space normally occupied by a single-level terminal, making them particularly useful where panel space and wiring density are important. The MA2.5/5.D1.1 combines this compact arrangement with screw-clamp connections to provide secure and accessible termination for industrial signal and control wiring.
Its vertically interconnected double-deck configuration allows a common potential to be distributed between connection points while reducing the need for additional external wiring or bridging. Combined with its 5 mm width and compatibility with common DIN rail formats, the 1SNA115530R1200 is well suited to compact automation cabinets, machinery and instrumentation systems.
Typical Applications
- High-density industrial control panels.
- PLC and automation system wiring.
- Signal and instrumentation circuits.
- Machinery and production equipment.
- Electrical distribution and control cabinets.
- OEM electrical and automation assemblies.
