Hubbellock® Devices
Plugs and Connector Bodies
Features and Benefits
Note: Above cut-away view and call-outs are construction elements pertaining specifically to the 30A Hubbellock series.
While the Hubbellock contact interface design applies to all, there are construction elements that are different, depending on the amperage.
Three-piece thermoplastic clamp assembly
with fast-lead stainless screws provides a
more consistent durable grip. Grommets
provide a sealed cable entry that protects
against the entry of moisture and dust
Superior wire terminations are assured
with box terminals and screws with
pressure pads. This design captures stray
wire strands and permits more clamping
pressure on the wire without damaging it.
Loosening of terminations and resulting
heat build-up are greatly reduced
Impact resistance in the interior of the
female device comes from a strong
thermoplastic material
No “lazy” connections because a spring-
loaded safety shutter automatically ejects
the plug if it hasn’t been properly locked
into the female device. This eliminates
teasing of the contacts, a major cause
of contact burn-up
Arcs are snuffed out, when devices
are mated or unmated under load, by
spring-loaded safety shutter
Longer contact life is assured by
supplementary springs. Other
devices rely just on contacts
themselves to provide proper
contact pressure Enhanced safety because access to
live female contacts is restricted by the
spring-loaded safety shutter
Positive locking is ensured by the nose
of the plug being keyed into
a detent in female device. This lock is
independent of the contacts or
a separate mechanical lock
Insulated non-metallic housing
enhances safety and abuse
