It accepts 14-22 AWG wire and is rated 10 A at 300 V, with a vertical (top-entry) mating orientation. The green polyamide 6/6 housing carries brass contacts with nickel-tin plating, and the clamp material is stainless steel. This is a single-level block meant for control panels, lighting ballasts, HVAC controllers, and any board-level power distribution where you want to land a field wire without a screwdriver.
The push-in spring clamp accepts solid or ferruled stranded wire from 14 AWG down to 22 AWG. No screw to torque — strip the wire, push it into the cage, and the stainless spring holds it. The clamp material is stainless steel, so it won't corrode in a damp cabinet.
