The 3RV102, 3RV103, and 3RV104 MSP?s can be used as Type E self-protected manual combination starters per UL508 (3RV102 and 3RV104 require additional terminal adapers) or as components in Group Installation per NEC 430-53(C) to turn motors on and off. Each device has built-in heater elements that provide overload protection and magnetic trip elements to protect the motor. When the 3RV is used as a component in Group Installation, multiple MSP?s can be installed below one circuit breaker to protect its own motor. A contactor can be mounted to the MSP to provide a remotely operated starter
