2E4UM产品概述
UL® listed to UL508 and CSA certified to C22.2 No. 14 V-EA manual motor controllers are horsepower rated for AC across-the-line motor starting, suitable for motor disconnect means and overload protection. They also can be used for AC general use, AC resistance, AC discharge lamps and AC incandescent lamps. Altech/ABL SURSUM V-EA miniature DIN rail mount circuit breakers provide an opportunity for major cost and installation time savings and superior circuit protection. Six trip characteristics are UL® listed. All trip characteristics are internationally defined and accepted. The “G” characteristic matches USA and Canadian thermal/magnetic trip norms. All rated currents have the same housing dimensions and terminal sizes. The V-EA can be loaded with full rated current (100% breaker). Recognized with Line/Load reversibility, i.e., power feed can be field or factory wired to the screw-cage clamp terminals at the “top,” range 18 AWG to 3 AWG, or at the “bottom,” range 18 AWG to 2 AWG. The V-EA/U is intended for OEM industrial applications.
