Why Choose the TE Connectivity DR2.5/10.P.4L 1SNA290219R1200 Ground Terminal Block?
The TE Connectivity / Entrelec DR2.5/10.P.4L 1SNA290219R1200 is a compact four-connection ground spring terminal block from the SNA range, designed to provide protective-earth conductor termination in industrial electrical panels. Its distinctive green-yellow housing provides immediate visual identification of the protective-earth function within a terminal assembly.
Designed as a 2.5 mm² Miniblock, the DR2.5/10.P.4L uses spring-clamp conductor connections together with a screwless rail connection. The compact angled design, front wiring entry and 10 mm spacing help simplify conductor access while conserving space in densely populated control and automation cabinets.
The 1SNA290219R1200 mounts on TH 15-5.5 DIN rail and accepts flexible conductors from 0.12–2.5 mm² and rigid conductors from 0.12–4 mm². Spring-clamp technology maintains contact pressure independently of installer-applied tightening torque and automatically compensates for conductor settling, supporting reliable long-term protective-earth connections.
Key Advantages
- Dedicated protective-earth ground terminal block for industrial panel wiring.
- Four conductor connections within a compact Miniblock format.
- Spring-clamp conductor termination provides consistent contact pressure.
- Screwless rail connection simplifies protective-earth integration with the mounting rail.
- Compact 10 mm width helps conserve DIN rail space.

Reliable Protective-Earth Connections for Compact Control Panels
Protective-earth connections are fundamental to electrical panel safety, making dependable conductor termination and clear identification essential. The DR2.5/10.P.4L combines spring-clamp conductor termination with a screwless rail connection, allowing the terminal to provide an organised grounding point while maintaining consistent conductor contact pressure without installer-controlled screw torque.
The compact angled profile and front wiring entry simplify installation in space-constrained assemblies, while the green-yellow housing clearly distinguishes the protective-earth circuit from other terminal functions. With four connection positions in a 10 mm-wide format, the 1SNA290219R1200 is particularly useful where several protective-earth conductors need to be terminated within a compact DIN rail assembly.
Typical Applications
- Protective-earth wiring in industrial control panels.
- PLC and automation cabinets.
- Machine control and OEM electrical equipment.
- Compact DIN rail grounding assemblies.
- Industrial power and distribution panels.
- Process control and instrumentation cabinets.
- Protective conductor termination in machinery and automation systems.
