About these results

This decoder reads published manufacturer catalog-number conventions and returns the most likely configuration. It is an identification aid, not a specification: numbers get reused and revised, nameplates get mis-stamped, and some factory-fitted options never appear in a type designation at all. Confirm any result against the breaker’s own nameplate and the manufacturer’s documentation before ordering a part, fitting a replacement, or relying on a rating.

Power circuit breakers are hazardous equipment. Installation, testing and maintenance are work for qualified personnel following NFPA 70E and the equipment manufacturer’s instructions. This tool is provided as is, without warranty of any kind, and Voyten Electric & Electronics, Inc. accepts no liability for loss, damage or injury arising from reliance on decoded output.
