This series of Siemens Sirius 3RV2021 manual motor starters are approved for Type E protection, otherwise known as a self-protected combination motor controller. With a UL approval, the 3RV2021-0HA15 can be used downstream of a fuse or circuit breaker to provide this level of protection up to 0.63 AMPS. The benefit is that all these protections are provided in one device: overload and short circuit protection, disconnect and motor control. When combined with a the appropriate sized Siemens 3RT2 contactor, full combination motor protection is achieved in one compact, fully functional unit. Contact Kent Industries today at 800.222.5129 so that we can determine the appropriate size and range needed for your application as our staff is fully trained and has over 60 combined years in motor controls.
