This molded case thermal magnetic circuit breaker is designed for demanding commercial and light industrial distribution panels where compact ED frame devices are specified. Rated 100 A at 40 °C in a 3‑pole configuration, it supports 480 VAC systems at 50/60 Hz with UL489 certification and CSA C22.2 compliance. The ED4 trip unit combines a time‑delay thermal element for overload protection with an instantaneous magnetic element for short‑circuit events. Interrupting capability is 65 kA at 240 VAC and 18 kA at 480 VAC under UL ratings. The unit is supplied with load side lugs and accepts field‑installed line side lugs when required. It mounts as a plug‑in device for P1 through P5 panelboards and accommodates 10 to 1/0 AWG copper or aluminum conductors. Dimensions are approximately 6.35 H x 3.00 W x 4.56 D inches, and typical weight is about 2 lb. This Sentron series ED frame breaker features a blue label and panel mount orientation, making it a reliable replacement or new install choice in switchboards, panelboards, and individual enclosures.
