The 3RV102, 3RV103 AND 3RV104 MSP's can be used as TYPE E self-protected manual combination starters per UL508 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 3RV102, 3RV103 or 3RV104 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.
