1sna146201r0400 – dr 4/6 p,ex

Why Choose the TE Connectivity 1SNA146201R0400 DR4/6.P.Ex Terminal Block?

The TE Connectivity 1SNA146201R0400, also known as the DR4/6.P.Ex, is a compact green/yellow protective earth screw clamp terminal block designed for dependable grounding connections in industrial control panels, automation equipment and appropriately engineered hazardous-area installations. Part of the established ENTRELEC SNA Mini Blocks range, it combines secure screw clamp termination with a space-saving design for 15 mm DIN rail installations.

The DR4/6.P.Ex provides a dedicated protective earth connection between field conductors and the mounting rail. Its green/yellow housing gives immediate visual identification of the protective earth function, while the screw clamp connection provides secure conductor retention for industrial electrical installations. The compact Miniblock format is particularly useful where panel space is limited.

With a 4 mm² rated cross-section and a narrow 6 mm terminal spacing, the DR4/6.P.Ex provides a compact grounding solution for industrial equipment. The terminal mounts on TH15-5.5 DIN rail in accordance with IEC 60715 and is an Ex / ATEX component covered by certificate LCIE 02 ATEX 0024 U for incorporation into appropriately designed hazardous-area electrical systems.

Reliable Protective Earth Connections for Industrial Systems

Protective earth terminal blocks provide an organised connection between protective conductors and the equipment grounding system. The DR4/6.P.Ex uses a screw clamp termination and DIN rail mounting arrangement to provide a compact grounding point within industrial electrical panels, helping panel builders create clearly identified and serviceable protective earth connections.

The compact Miniblock format is particularly useful in installations where DIN rail space is restricted. Its green/yellow housing identifies the grounding function at a glance, while the Ex / ATEX configuration allows the terminal to be incorporated into appropriately designed explosion-protected systems used in process automation and other demanding industrial environments.

Typical Applications

• Protective earth connections in industrial control panels.
• Machine and equipment grounding systems.
• Process automation and instrumentation installations.
• Appropriately engineered hazardous-area electrical systems.
• PLC and automation control cabinets.
• Compact DIN rail assemblies using 15 mm mounting rail.
