MS-Series Circuit Breaker Carling Technologies’ MS-Series Sealed Toggle Circuit Breaker was designed and tested to operate flawlessly in the harshest of environments. Ideally suited for COTS (commercial off the shelf ) military applications, the MS-Series features a durable metal and sealed mounting bushing with MIL-PRF-39019F ingress protection when mounted in a panel. This class-leading, affordable circuit breaker was also designed in accordance with the requirements of MILPRF-55629 and MIL STD 202, making it the best choice when the application consideration includes shock, vibration, moisture resistance, salt spray and thermal shock. The MS-Series’ compact size and reliability make it ideal for ruggedized communication equipment and other mission critical equipment.
