Why Choose the WAGO 2202-2707 Double-Deck Ground Terminal Block?
The WAGO 2202-2707 is a compact 4-conductor double-deck protective earth terminal block designed for reliable grounding connections in industrial control cabinets, machinery and electrical distribution systems. Part of the WAGO TOPJOB® S 2202 Series, it combines a 2.5 mm² nominal cross-section with Push-in CAGE CLAMP® technology and push-button actuation for fast, secure and maintenance-friendly conductor termination.
Unlike a conventional double-deck through terminal, the 2202-2707 is specifically designed as a PE protective earth terminal. Its four conductor connection points are internally commoned to a single protective earth potential across two levels, providing a space-saving way to connect multiple protective conductors to the DIN-rail grounding system. The green-yellow housing provides immediate visual identification of its protective earth function.
The WAGO 2202-2707 accepts solid and fine-stranded copper conductors from 0.25 to 4 mm² and supports direct push-in termination for suitable conductors. At only 5.2 mm wide, the two-level design provides four PE connection points while conserving valuable DIN-rail space. It is suitable for DIN-35 × 15 and DIN-35 × 7.5 mm rails, including specified Ex e II applications, and is supplied in a pack of 50.
Key Advantages
- 4-conductor double-deck PE design provides multiple protective earth connections in minimal DIN-rail space.

Space-Saving Double-Deck Protective Earth Distribution
Double-deck protective earth terminals are particularly useful where multiple PE conductors must be terminated in a limited amount of DIN-rail space. The WAGO 2202-2707 provides four conductor connection points across two levels, with all positions internally commoned to a single protective earth potential. This allows several protective conductors to be grouped efficiently without requiring separate single-level terminals.
Push-in CAGE CLAMP® technology uses spring pressure to maintain reliable conductor contact without conventional screw clamping. Suitable solid and ferruled conductors can be inserted directly, while the integrated push-buttons provide convenient operation when terminating other conductor types or removing existing wiring. The result is a compact, clearly identifiable and maintainable grounding solution for professional electrical installations.
Typical Applications
- Protective earth distribution in industrial control cabinets.
- High-density grounding connections in DIN-rail terminal assemblies.
- Machine building and factory automation systems.
- PLC, sensor and actuator control panels requiring PE connections.
- Switchgear and low-voltage electrical distribution assemblies.
- Equipotential bonding and protective conductor installations.
