MS IP68 Hydraulic-Magnetic Circuit Breakers

Carling Technologies MS IP68 Hydraulic-Magnetic Circuit Breakers are designed/tested to operate in harsh environments and are suited for COTS (commercial off-the-shelf) military applications. A space-saving envelope meets IP68 requirements and features a durable metal and sealed mounting bushing with MIL-PRF-39019F ingress protection when mounted in a panel. The cost-effective design complies with the requirements of MIL-PRF-55629 and MIL-STD 202. The MS Circuit Breakers are compact, reliable, and ideal for crucial communication equipment and other mission-critical components where shock, vibration, moisture resistance, salt spray, and thermal shock are a consideration.
