60 A 480 V mechanical interlock

This Hubbell watertight interlock receptacle provides a grounded three-phase connection rated for 60 A at 480 V AC. It suits industrial power distribution where a locking handle and non-fused construction are required. The thermoplastic housing resists moisture ingress for reliable service in wet locations.

Pin-and-sleeve plug compatibility

The device accepts only the matching pin-and-sleeve plug with manufacturer part number 5Z917. Using any other plug type will prevent the mechanical interlock from engaging and void the watertight seal.

Screw-terminal wiring up to 2 AWG

The receptacle terminates four conductors in screw terminals that accept up to 2 AWG wire. The locking handle must be fully seated before energising the circuit; failure to lock it is the most common installation error.

Questions about this item

What does the 30 hp motor rating mean when the receptacle is installed in a three-phase 480 V circuit?

It indicates the maximum three-phase motor load the interlock can switch at 480 V AC without a fuse, based on the 60 A current rating.

How does the pin-and-sleeve interface with the 5Z917 plug limit the connection in practice?

The 4-wire, 3-pole plug locks into the watertight receptacle, providing a grounded 60 A, 480 V AC connection that cannot be disengaged while the handle is locked on.

What physical space and wiring are required to mount this thermoplastic interlock?

The housing accepts up to 2 AWG conductors and mounts as a watertight mechanical interlock; exact cut-out dimensions are not supplied in the data.
