Designed for versatile mounting, the Siemens ED63B060L is a 3-pole, 60A molded case circuit breaker. As part of the SENTRON ED frame family, it utilizes fixed thermal and magnetic trip units for dependable long-time and instantaneous fault protection. Unlike bolt-on variants, this unit mount breaker includes both line and load lugs out of the box. It installs easily into individual enclosures and switchboards. With a 25kAIC rating at 480VAC, it meets strict UL 489 and IEC standards.
