Cutler Hammer Contactor, Retrofit of obsolete contactors.
In the industrial world, unexpected downtime can result in huge financial losses and production delays. Recently, an industrial company contacted Maghispan after facing a very common situation: a failure in several Cutler Hammer CE15SN3 contactors, which had been discontinued by the manufacturer, with no possibility of purchasing official spare parts.
The problem: obsolete contactors and paralysed production
This company, which operates in the chemical sector, ran a critical facility whose control system relied on Cutler Hammer CE15SN3 contactors. After years of flawless operation, some of these contactors started having issues with their fixed and moving contacts, causing line stoppages.
Al consultar con proveedores habituales, confirmaron que tanto el CE15SN3 como otros modelos de la serie CE15 estaban descatalogados:
- CE15CNC3A – 5.5 kW, 110 V NC
- CE15CNC3K – 5.5 kW, 240 V NC
- CE15CNS3K – 5.5 kW, 240 V NO
- CE15BNS3A – 4 kW, 110 V NO
- CE15BNS3K – 4 kW, 240 V NO
- CE15CN4A – 5.5 kW, 110 V, 4 poles
- CE15HN3A – 22 kW, 110 V
- CE15JN3TB – no replacement currently available
For models such as the CE15SN3, replacement with alternative models involved costly electrical and frame redesigns, severely affecting production.
