277 VAC , Single Pole Circuit Breakers
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. Technical Specifications. Voltage Rating: 480Y/277 VAC (480 VAC phase-to-phase, 277 VAC phase-to-ground/neutral). Interrupting Capacity: 10 kA with UL® listed RK5 back-up fuse or MCCB. Electrical/Mechanical Endurance: 10,000 ON/OFF operations. Calibration Temperature: 40°C (104°F). Terminal Tightening Torque: 20 lbf-In. International Approvals: For various trip characteristics and rated currents, Germanischer Lloyd, SEV, SEMKO, NEMKO, etc. VDE approved on up to 25 A on B, C, and D-trip. CE mark is standard.
Thermal one-hour trip zone 1.13 to 1.45 times V-EA rated current (RC); magnetic 100 ms trip boundary 3 to 5 times RC.
It’s application is business equipment, wiring, protection, lighting, appliances, control circuits, some motors and some electronic applications. Relatively long thermal trip delay but low magnetic trip point.
