Eaton GHB1030 Molded Case Circuit Breaker MCCB

The Eaton GHB1030 molded case circuit breaker (MCCB) is a 1-pole, 30-amp device in Eaton's NSB GHB1030 family, designed to interrupt fault currents on a single branch circuit within electrical distribution panels and enclosures. As a molded case breaker, it provides compact protection for circuits inside assemblies where space is limited and is commonly used in panelboards and switchgear to interrupt current during overcurrent events. The 1P 30A rating specifies the maximum continuous current the device is intended to carry before tripping, enabling electricians to size wiring and protection for a single leg of a distribution circuit in accordance with standard electrical practices. Being part of the Eaton NSB GHB1030 line, this MCCB aligns with Eaton's protection products and accessories, helping maintain consistent circuit protection within Eaton-based installations and simplifying the selection when a 30-amp, 1-pole MCCB is required.
