Siemens E43A010 Motor Protection Circuit Breaker

Siemens E43A010 is a 3-pole motor protection circuit breaker in the ITE/E4-A ETI family, rated at 10 A and designed to protect three‑phase motors on 480 V systems. This molded‑case device provides motor overload and short‑circuit protection for motor feeders in industrial control panels, conveyors, pumps, fans, and similar equipment. The 3‑pole configuration ensures all three live conductors disconnect simultaneously on trip, helping meet standard motor protection requirements in 3‑phase systems. As part of the E4‑A ETI lineup, the E43A010 offers a fixed 10 A rating suitable for motors whose full‑load current sits at or below that value, delivering dedicated motor protection within a compact, panel‑mount form factor.
