Description
Part of the classic Westinghouse E-frame family, this 2-pole, 30A molded case circuit breaker ensures dependable overcurrent protection for 240VAC circuits. This legacy component installs into older Westinghouse and Eaton panelboards using a standard bolt-on configuration. It eliminates the need for retrofit kits and is officially replaced by the newer EHD2030 model. With a 7kAIC interrupting capacity, the breaker relies on fixed thermal and magnetic trip mechanisms to safely clear faults.Specifications

Product FAQs
7 answersWhat panelboards accept the E2030 circuit breaker?
The E2030 is a legacy E-Frame breaker designed to bolt directly into classic Westinghouse and Eaton panelboards. It is commonly used by maintenance teams to restore power without modifying existing enclosures.
Is the Westinghouse E2030 the same as the Eaton E2030?
Yes. Eaton acquired the Westinghouse electrical distribution division, meaning Eaton, Cutler-Hammer, and Westinghouse E-Frame breakers sharing this catalog number are physically and electrically identical.
Do I need to purchase separate lugs for the E2030?
No, the E2030 comes with factory-installed lugs that accept 14 AWG to 1/0 AWG copper or aluminum conductors, allowing for immediate termination upon installation.
Can the E2030 be used in direct current (DC) systems?
Yes. While primarily used in 240VAC systems, this breaker is also rated for 125/250VDC applications, making it suitable for specific industrial DC control panels or battery systems requiring up to 5kAIC protection.
What safety precautions should be taken when installing the E2030?
Because this is a bolt-on breaker that connects directly to the panelboard bus, the entire panel must be de-energized before installation or removal to prevent arc flash hazards and ensure installer safety.
Can I adjust the trip curve on the E2030 for specific loads?
No. The E2030 utilizes a fixed thermal and fixed magnetic trip unit. The long-time overload and instantaneous short-circuit thresholds are factory calibrated and cannot be altered in the field.
What type of protection does the LI trip function provide?
The LI designation means the breaker includes Long-Time (L) protection for sustained overloads and Instantaneous (I) protection for immediate short-circuit clearing, which is the standard configuration for general power distribution.
