The HUBBELL GFP515A is a robust ground fault circuit interrupter (GFCI) receptacle engineered for demanding industrial and commercial environments. Its patented AUTOGUARD self-test technology continuously monitors the GFCI's functionality, automatically disconnecting power if critical components are damaged and protection is compromised. This feature, mandated by UL943 standards, ensures ongoing safety and reliability. The GFP515A also incorporates visual indicators for power status, trip conditions, and end-of-life status, providing users with clear and immediate feedback. Its construction includes a thermoplastic nylon housing for high impact and ultraviolet resistance, ensuring durability in harsh conditions. The device also features protection against line and load reversal, preventing false assumptions of protection if improperly wired. This GFCI is ideal for applications requiring reliable ground fault protection and enhanced safety features.
