The sound-attenuated aluminum enclosure helps reduce operating noise and protects internal components from outdoor conditions. Removable access panels simplify routine inspection and servicing. Mobile Link™ connectivity allows remote monitoring of generator status and maintenance information through compatible connected devices.

Designed with installation flexibility in mind, the Protector Series supports code-related accessories and configurations to help meet applicable installation requirements.
