HubbellHBL430MI7WCircuit-Lock Mechanically Interlocked Pin and Sleeve Receptacle, 30 A 480 V 3-Phase Delta, 3P4W, IP67 / NEMA 4X, Unfused

Product Description

What this part is:

Hubbell Wiring Device-Kellems HBL430MI7W Circuit-Lock mechanically interlocked receptacle: an IEC pin and sleeve female receptacle combined with a disconnect switch in one enclosure, mechanically interlocked so the two operate together. Function: Mechanically interlocked pin and sleeve receptacle with disconnect switch. Product Line: Hubbell Circuit-Lock, IEC pin and sleeve, industrial grade. Device Type: Female receptacle, mechanically interlocked. Current Rating: 30 A. Voltage Rating: 480 V AC, three-phase delta. Configuration: 3-pole, 4-wire grounding (3P4W). Motor Rating: 15 hp. Fusing: Unfused. Enclosure Rating: IP67, NEMA 4X outdoor, NEMA 12 indoor. Termination: Terminal screws. Approvals: UL, cUL and CSA. Catalogue Number: HBL430MI7W. Unit Quantity: 1 Pc.

Decoding the designation:

HBL — Hubbell catalogue prefix. The device also appears as 430MI7W with the prefix dropped.

4 — four-wire configuration.

30 — 30 A rating.

MI — mechanical interlock.

7W — IEC 60309 pin-and-sleeve configuration for 480 V three-phase delta. An F before the 7W, as in HBL430MIF7W, marks the fused version.

What these specs mean in practice:

The plug cannot be inserted or withdrawn while the switch is closed, and the switch cannot be closed until the plug is fully seated. The connection is always made and broken dead, so no arc forms across the pins. Pin and sleeve contacts are not rated to make or break load current, and an interlocked receptacle is what allows them to be used on a load that may be energised.

Three-phase delta at 480 V with three poles and a ground, and no neutral, is the configuration used for motor and machine loads. The 15 hp figure states the motor load the switch handles at that voltage.

The IP67 rating covers dust ingress and temporary immersion; the NEMA 4X and NEMA 12 ratings cover hosedown and corrosion outdoors and dust and dripping liquids indoors. Together they suit wash-down areas, outdoor plant and portable equipment connections.

Mounting data:

Mounting: wall or machine frame, surface mount enclosure. Termination: screw terminals. The enclosure suits non-metallic enclosures and metallic conduit. Supply enters the switch side; the receptacle presents the IEC 60309 pin pattern for 480 V three-phase delta. Interlock: factory set.

Quantity and configuration:

Unit Quantity: 1 Pc. One interlocked receptacle assembly.
