Siemens ED42B100 2 Pole Molded Case Circuit Breaker

Siemens Sentron ED42B100 is a 2-pole molded‑case circuit breaker (MCCB) in the ED4 family, rated for 100 A at up to 480 V AC, with an 18 kA interrupting capacity. This bolt‑on device uses a thermal‑magnetic trip unit (long‑time and instantaneous) and includes load‑side lug terminals for secure conductor termination, pairing robust protection with straightforward field service. The ED42B100 supports systems up to 600 V AC and is rated for 40°C ambient operation, making it suitable for indoor distribution panels in commercial and light‑industrial environments where reliable short‑circuit and overload protection is required. As part of Siemens’ ED4 lineup, it offers ED‑frame compatibility for replacement or integration within Siemens panels and other ED‑frame assemblies, with the standard ED‑frame mounting and connection style. The 2‑pole configuration and 100 A rating provide precise protection for feeders and branch circuits, ensuring predictable trip characteristics and compatibility with typical wiring methods in low‑voltage distribution schemes.
