High-Ampacity Single-Pole Male Receptacle
The Hubbell HBLMRSY Series 16 male receptacle is designed for industrial and commercial power distribution requiring secure, high-current connections. It accepts conductor sizes ranging from #4 AWG to 4/0 AWG, making it suitable for heavy-duty cable terminations. The device features a threaded stud terminal with screw terminals for reliable conductor retention. Its thermoplastic elastomer housing provides durability in demanding environments.
600V AC and 250V DC Voltage Limits
This single-pole device supports a maximum of 600V AC or 250V DC with an amperage rating of 300/400A AC/DC. The NEMA Type 12, 3R, and 4X enclosure ratings indicate protection against dirt, rain, splashing water, and hose-directed water. These ratings define the practical environmental limits for safe operation. Installers must ensure the application voltage and environmental conditions remain within these specified boundaries.
Replaces Lower-Rated or Non-Threaded Single-Pole
This receptacle upgrades installations previously using lower ampacity devices or non-threaded terminal types that may loosen under vibration. The jump is justified when conductor sizes exceed #4 AWG or when NEMA 4X wash-down protection becomes necessary. It is not suited for applications requiring multi-pole configurations or voltage ratings exceeding 600V AC. Buyers needing neutral or ground poles must source separate devices.
