Siemens ED23B030 Three-Phase Molded-Case Circuit Breaker

Siemens ED23B030 Sentron 3P molded-case circuit breaker is a three-phase protective device rated 30 A at 240 VAC, part of the ED frame family and commonly listed as ITE Sentron ED23B030. It employs a thermal-magnetic trip mechanism to provide both overload and short-circuit protection, with an interrupt rating of 10 kA at 240 VAC for reliable fault clearing in typical distribution panels. The unit is a 3-pole ED-frame breaker designed for use in low-voltage switchgear and panelboards to safeguard feeders to motors, pumps, fans, conveyors, and control circuits in commercial and light-industrial applications. Load-side lug terminals are included for straightforward termination; line-side lug terminals are not included, aligning with common ED-series mounting configurations. Compatible with Siemens Sentron ED-series catalog components and with panels that accept ED-type breakers, the ED23B030 accommodates 50/60 Hz electrical systems. Its molded-case form factor and thermal-magnetic protection suit standard three-phase protection for branch circuits and motor loads without requiring a larger distribution breaker, while its 10 kAIC rating supports moderate fault levels. The ED23B030 is widely stocked by distributors and appears in Siemens' ED family listings and product catalogs under the Sentron brand name.
