The ABB a2a200nrw150ecb is a 150-amp enclosed circuit breaker housed in a NEMA 3R enclosure, designed for use in electrical distribution systems where outdoor or weather-resistant protection is required. This unit integrates the Formula A2A breaker within a factory-assembled enclosure, providing overcurrent protection in a ready-to-mount package. Licensed electricians install this type of assembly in service entrance, feeder, and branch circuit applications where a standalone enclosed breaker is specified by plan or code. The NEMA 3R rating means the enclosure resists rain, sleet, and external ice formation.
This enclosed breaker is suited for residential and light commercial electrical installations where outdoor-rated overcurrent protection is required. Typical applications include main disconnect service at detached structures, agricultural buildings, pool equipment pads, and similar locations where a weather-resistant enclosed breaker is specified. The factory-assembled design reduces field wiring time and supports installations governed by NEC requirements for service disconnecting means.
Designed as an OEM-style enclosed circuit breaker assembly for use in residential and light commercial electrical distribution applications requiring a NEMA 3R rated enclosure.
Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize the upstream service before beginning any wiring connections to this enclosure. Verify that conductor sizing, conduit entry, and grounding methods meet NEC requirements for the application. Do not exceed the marked ampere rating of the breaker.
