E1030 - 30Amp Circuit Breaker

E1030 - 30 Amp Circuit Breaker

The E1030 circuit breaker is a 1-pole, 30-amp thermal-magnetic breaker designed for dependable circuit protection in legacy electrical distribution systems operating at 120VAC. Built with a non-interchangeable trip unit and rated for 40°C ambient conditions, this breaker helps protect branch circuits from overloads and short circuits while maintaining the proper form, fit, and function required for compatible panelboard installations. Its 10k A.I.C. interrupting rating supports safe interruption of fault currents within its design limits. The unit includes load terminals for straightforward installation and secure connections. Designed with durability in mind, breakers of this type were built to last and continue to serve as reliable replacement components when maintaining or servicing existing electrical equipment.

Key Features and Benefits

• 30 Amp Current Rating: Designed for branch circuit protection in 120VAC electrical systems.
