EATON Specialty Breakers - Engine Generator Circuit Breakers
Engine Generator Circuit Breakers Product Overview
Product Description
Eaton’s engine generator molded case circuit breakers are designed specifically for application on diesel engine powered standby generators where high interrupting circuit breakers are not required. The JG through NG breakers are equipped with a special trip unit, that includes standard thermal (overload) protection and special low magnetic pickup range (FG includes a fixed thermal-magnetic pickup). The standard thermal trip unit provides overload protection for conductors per the National Electrical Code®. The low magnetic pickup range is approximately two to five times the continuous rating and provides closer low-level short-circuit protection when applied on generators that have very low short-circuit capacity. This combination allows the user to customize the breaker to the generator output.
Application Description
Engine generator circuit breakers are suitable for reverse feed application.
Standards and Certifications
Engine generator molded case circuit breakers are designed to conform with the following standards:
- Underwriters Laboratories Standard UL 489, Molded Case Circuit Breakers and Circuit Breaker Enclosures File E7819
- Canadian Standards Association Standard C22.2 No. 5, Service Entrance and Branch Circuit Breakers
- International Electrotechnical Commission Recommendations IEC 947-2, Circuit Breakers
Conformance with these standards satisfies most local and international codes, assuming user acceptability and simplified application.
