Applies to circuit breaker type ML1, ML-1.
Circuit breaker types ML, ML-1, are obsolete, and no longer available. Current style circuit breakers will not fit into the place of the old circuit breakers. For many years, we did offer adapter kits (e.g. SK4515) that allowed newer breakers to be installed into the old panelboards.
Another solution is to replace the complete panelboard and breakers with currently available products.
Note: New panels will not be the same exact size as the older panels, and will likely be larger due to wire-bending space changes over the years.
For assistance in selecting replacement products, first gather as many details as possible of the existing equipment. This includes information such as voltage, amps, number and size of the circuit breakers, type of enclosure, etc. Taking pictures of the complete panel with breakers may also help. Then, contact your local Schneider Electric authorized distributor, or you local Schneider Electric Field Office.
