The HBL2815ST is a 30 A, 4-pole/5-wire Twist-Lock flanged inlet rated for 3-phase Y 120/208 V applications with patented screwless spring termination technology. The device features strong steel springs that continuously apply pressure to wires, ensuring secure connections that remain tight even under constant vibration and abusive industrial environments. Termination is accomplished in approximately 11 seconds by simply inserting the wire and pressing the plunger down—no tools or torque wrench required—making it compliant with NEC code 110.14(D) without requiring torque verification. The flanged inlet is designed with easy termination access from the back and laser-etched terminal markings for clear wiring identification. Common applications include OEM equipment, machine manufacturers, data center power distribution, and industrial production facilities where rapid, reliable installation of multiple devices is critical.
