Siemens ED41B020 Molded Case Circuit Breaker

Siemens ED41B020 Molded Case Circuit Breaker is a compact, single-pole protective device rated for 20 amps at up to 480 volts AC, engineered to interrupt fault currents in low‑voltage electrical systems and protect wiring in panelboards and feeders. The ED41B020 belongs to Siemens' ED4 molded‑case family and features a blue‑gray housing designed for standard Siemens installations in commercial and light industrial distribution. It provides a robust short‑circuit interrupting capability of up to 22 kA at 277 V AC and is offered in fixed, load‑side lug termination for secure connections, supporting reliable field replacements in existing Siemens panels. Common applications include branch protection in distribution panels, motor circuits, and other low‑voltage power distribution where precise one‑pole protection is warranted.
