Eaton's low-voltage air circuit breaker replacement advantages:

Meets or exceeds IEEE/ANSI standards
Downtime reduced since no parts are reused from original breaker
Reduces normal maintenance to 2-6 hours per breaker
Common components utilized across product line, reducing spare parts inventory
Renewal parts stocked for circuit breakers currently in production, eliminating parts availability issues

Short circuit interrupting upgrades available with bus bracing analysis
Optional Arcflash Reduction Maintenance System feature can be integrated to provide protection for downstream loads during maintenance and arc flash reduction
Replacement breakers available for multiple generations of Westinghouse, Allis-Chalmers, Federal Pacific, General Electric and ITE

Low-voltage breaker to vacuum starter replacements

Electric utility generation and process industries often apply circuit breakers as motor starters even though they are not intended for these applications. A better approach is Eaton’s LV breaker-to-vacuum motor starter replacement, which uses state-of-the-art vacuum contactors that have a long life and are resistant to environmental contaminants.

Specifically designed to replace breakers used as motor starters, the advantages of low-voltage vacuum starter replacement include:

Tested to IEEE/ANSI standards
Passive and active interlocking
May be applied up to 600 VAC and 425 A continuous
Switching duty life of up to 150,000 operations

Motor protection provided through Eaton's self-powered C440 Electronic Overload Relay, which provides selectable thermal overload protection, phase loss and ground fault
Designs available to replace select models of Westinghouse type DB-25 and DBL-25, Westinghouse Type DS-206, DSL-206 and DS-416, General Electric AK-2A and ITE K600, K1600, and KDON-600 breakers

Remote power racking system (RPR-2.1)

Eaton’s RPR-2.1 enables remote racking of many manufacturers' low- and medium-voltage circuit breakers that can be inserted or removed using the rotation of a shaft. Operators may remain 25 feet or more away from the switchgear door during the racking process, which is outside of the arc flash protection boundary.
