Industrial ESA-14KA Three Pole Circuit Breaker

Industrial IEM ESA-14KA three-pole circuit breaker, model ESA-14KA, is a three-phase overcurrent protection device rated for 90 amperes at 480 VAC. It interrupts all three conductors of a 3-phase power system, providing synchronized disconnection to safeguard equipment, wiring, and panels from overloads and short circuits. This unit is designed for industrial electrical installations where reliable 480 VAC distribution is required and can be installed in panelboards and switchgear to protect circuits feeding industrial machinery or control panels operating on 480 VAC. With a 90 A rating, it is intended to carry operating currents up to that threshold and trip when fault current exceeds its setting. Three-pole design ensures simultaneous disconnection of all lines, which can simplify lockout/tagout procedures during maintenance. In applications where three-phase power is standard—such as manufacturing floors, processing facilities, or heavy equipment enclosures—the ESA-14KA provides dependable, coordinated protection for 480 VAC distribution systems.
