JINH Grounding Terminal Blocks
JINH USLKG series grounding terminal blocks are designed for protective-earth wiring in DIN rail assemblies. They provide a clearly identifiable connection point for equipment grounding conductors and help route fault current toward the grounding system when installed as part of a properly designed protective circuit.
The series uses screw-clamp connections and mounts on TH35/7.5 DIN rail. Available models support rigid and flexible conductors across a broad range, from compact control-cabinet wiring to larger protective conductors.
- Series: USLKG2.5 to USLKG50
- Conductor range: approximately 0.2–50 mm², depending on model
- Mounting: TH35/7.5 DIN rail
- Connection: screw connection
- Operating temperature: -50°C to 100°C for the current series
What Is a Grounding Terminal Block?
A grounding terminal block—also called an earth or protective-earth terminal block—is used to join protective conductors to the grounding system inside an electrical enclosure. In a DIN rail assembly, it provides a dedicated, identifiable point for protective wiring and may establish a conductive connection to the rail according to its design.

One Series for Compact and Large Protective Conductors
The JINH USLKG range covers several conductor sizes so panel builders can use a consistent grounding-terminal format across control, automation and distribution equipment. Compact models support smaller protective conductors used for devices and control components, while larger models accept conductors up to 50 mm² for higher-capacity grounding requirements.
DIN rail mounting supports modular panel assembly and makes grounding points easier to identify, position and service. Screw connections provide a visible termination method that can be inspected during assembly and preventive maintenance.

Grounding Terminal Blocks FAQ
It provides a dedicated connection point for protective-earth conductors inside an electrical assembly and helps maintain a low-impedance protective path when the complete grounding system is correctly designed and installed.
A feed-through terminal connects conductors through an isolated current path. A grounding terminal is specifically designed for protective-earth wiring and may create a conductive connection to the DIN rail according to its construction.
The current product data specifies TH35/7.5 DIN rail mounting. Confirm rail dimensions and mounting compatibility in the individual product drawing.
The current USLKG range covers approximately 0.2 mm² to 50 mm², depending on model and whether the conductor is rigid or flexible.
The product tables provide separate ranges for rigid and flexible conductors. Conductor preparation and any ferrule requirement must follow the selected model’s instructions and applicable wiring standard.
Selection must consider conductor cross-section, required short-circuit performance, protective-device operation, rail system and the relevant equipment standard. Request the applicable technical and approval documents for the model under consideration.
