The SIEMENS ED42B080L is a 2-pole molded case circuit breaker rated for 480 volts and 80 amps, belonging to the ED4 series. It provides overcurrent and short-circuit protection in commercial and industrial electrical distribution systems. Licensed electricians install this breaker in panelboards and load centers where reliable branch-circuit or feeder protection is required at 480-volt service levels. The 2-pole configuration handles two-phase loads, making it suitable for motor loads, HVAC equipment, and other three-wire branch circuits commonly found in light commercial construction and industrial facilities.
This breaker is designed for use in commercial and industrial applications where 480-volt, 2-pole overcurrent protection is required. Typical installation scenarios include motor control panels, distribution panelboards, and switchboards in light industrial, warehouse, and commercial HVAC or mechanical room settings. The ED4 series is a standard frame class widely used in electrical distribution equipment requiring reliable thermal-magnetic trip performance.
Designed as an OEM-style replacement or direct-install 2-pole circuit breaker for commercial and industrial panelboards and load centers rated for 480-volt service that accept ED4 series molded case breakers.
Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize and lock out the panelboard or switchboard before removing or installing any circuit breaker. Verify that the enclosure and busbar rating are compatible with the breaker voltage and amperage before installation. Do not exceed the breaker ampere rating for the connected load.
