Selection & installation notes
- Order code: G7L-[1A or 2A]-[BDL, TUB or P]-[coil code]. Verify the exact available combination.
- The source gives 50,000 operations in the load-rating table and ≥100,000 in the general characteristics table. Use the duty-specific rating and request endurance confirmation for your load.
- Mount upright with the coil up; secure DIN-mounted BDL units with rail end stops. Use suitable RC/MOV suppression for inductive loads.
- The test button mechanically forces the contacts. Do not operate it during normal powered service. Avoid condensation, freezing, corrosive atmospheres and dust.
- Request a dedicated G20F datasheet before selecting G20F; G7L ratings must not be applied to it.
