The 387700111: Rated 15 A per circuit at 300 V. Accepts 14-22 AWG wire. Dual-wall barrier prevents shorting between adjacent circuits.
Top termination uses steel screws with a zinc, clear chromate finish — corrosion-resistant for industrial environments. The bottom is closed, meaning the screw terminal doesn't pass through to the other side; the wire seats against the bottom of the barrier. The flange on each end accepts a mounting screw for chassis or panel installation. The insulator material is polybutylene terephthalate (PBT), a glass-filled thermoplastic that holds up to heat and solvents common in control cabinets.
