Why Choose the TE Connectivity 1SNA110415R1200 D4/6.A.NTLP Terminal Block?
The TE Connectivity 1SNA110415R1200 is a compact D4/6.A.NTLP three-level installation terminal block designed for high-density electrical connections in industrial control panels, building installations and automation systems. Part of the established TE Connectivity ENTRELEC terminal block range, it combines proven screw clamp connection technology with a multi-level format that enables several circuits to be accommodated within a narrow section of DIN rail.
The D4/6.A.NTLP features three connection levels within a housing only 6 mm wide, helping panel builders maximise available wiring space while maintaining organised and accessible conductor termination. Its screw clamp connections provide secure mechanical and electrical contact, while the installation-style construction is designed to meet the dimensional requirements associated with DIN 43880 applications.
With a 4 mm² rated cross-section, 30 A rated current and 320 V rated voltage, the 1SNA110415R1200 is suitable for a wide variety of industrial and installation circuits. It accepts flexible and rigid conductors from 0.2–4 mm² and can be mounted on G32, TH35-7.5 or TH35-15 DIN rails, providing excellent installation flexibility.

High-Density Connections for Installation and Control Panels
Multi-level terminal blocks such as the TE Connectivity D4/6.A.NTLP allow several electrical connections to be arranged vertically within the space normally occupied by a single DIN rail terminal position. This helps reduce the overall rail length required for complex wiring systems while maintaining clear, accessible and serviceable conductor connections.
The D4/6.A.NTLP combines its three-level construction with proven screw clamp technology and a compact 6 mm width. Its grey, blue and green/yellow identification is particularly suited to organised installation wiring, while compatibility with several common DIN rail formats makes the terminal block easy to integrate into industrial control cabinets, distribution panels and automation equipment.
Typical Applications
- Industrial electrical control panels.
- Building and installation wiring systems.
- High-density DIN rail terminal assemblies.
- Industrial machinery and automation equipment.
- Power, neutral and protective conductor distribution.
- Electrical distribution and control cabinets.
- OEM machinery and panel building.
