Eaton 207132 T0-3-8401/I1 Reversing Cam Switch 3P 20A Surface

The Eaton T0-3-8401/I1 is a 20 A reversing switch from the Moeller T0 series, designed for surface mounting with a maintained 1-0-2 switching action and a center 0 (Off) position. It provides 3 contact units with 5 contacts across a 60 ° switching angle for reliable directional motor control. An IP65 degree of protection and a rated impulse withstand voltage of 6000 V AC suit it to demanding industrial panel applications.
