Product Details

The JDH catalogue lists JDH-1 to JDH-4 grounding clamp options with model-dependent conductor ranges. The photos show a bolted clamp and an earthing attachment. For a specific earthing procedure, confirm conductor fit, material, electrical and mechanical ratings, installation method and test documents for the selected model. Catalogue figures alone do not approve a safety-critical installation.
