Why Choose the TE Connectivity DR2.5/10.P.4L.EX 1SNA146263R0100 Ground Terminal Block?

The TE Connectivity DR2.5/10.P.4L.EX 1SNA146263R0100 is a green/yellow 2.5 mm² spring-clamp protective earth terminal block designed for compact grounding connections in industrial electrical and hazardous-area equipment. Part of the Entrelec Mini Blocks Spring range, it combines four connection points with a compact miniature DIN rail format for organised PE conductor distribution.

The DR2.5/10.P.4L.EX provides four spring-clamp connection points on a single level, allowing multiple protective conductors to be brought together at the same grounding terminal. Its green/yellow housing clearly identifies the protective earth function, while the spring connection technology provides efficient conductor installation without conventional screw tightening.

With a rated cross-section of 2.5 mm², a 10 mm width and dimensions of approximately 33 × 10 × 24.5 mm, this miniature terminal is designed for TH15-5.5 DIN rail mounting in accordance with IEC 60715. The DR2.5/10.P.4L.EX is also covered by the LCIE 02 ATEX 0029 U component certification family for integration into appropriately designed and certified Ex equipment.

Key Advantages

• Four spring-clamp connections provide compact multi-conductor protective earth termination.
• Dedicated ground / protective earth function with green/yellow identification.

Compact Four-Way Protective Earth Distribution

The four spring-clamp connection points of the DR2.5/10.P.4L.EX make it particularly useful where several protective conductors need to be terminated within a compact area. Instead of using multiple individual ground terminals, the four-way configuration provides an organised common protective earth connection while retaining a miniature DIN rail footprint.

Its spring connection technology also simplifies installation by eliminating routine screw tightening, while the green/yellow housing provides immediate identification of the PE circuit. Combined with its wide operating temperature range and Ex component certification, the terminal is well suited to industrial automation, instrumentation and hazardous-area equipment assemblies.

Typical Applications

• Protective earth and grounding circuits.
• Multi-conductor PE distribution.
• Industrial electrical control panels.
• Hazardous-area electrical equipment.
• Process control and instrumentation systems.
• Compact machine control cabinets.
• Factory automation equipment.
• OEM machinery and industrial panel building.
