Switch rated plugs and receptacles
with NEMA 4X protection
DSN Series products are switch and hp rated for quick, safe equipment changeouts. DSNs
are ideal for wet environments since they offer NEMA 4X watertightness as soon as the plug
is latched to the receptacle or as soon as the receptacle lid is closed.

Main Advantages


Switch & Hp rated (AC only)



100 kA short circuit rated*



NEMA 4X, IP66+IP67



Compact, lightweight design

Product Features
Operating
Instructions
OFF Button
Press to deenergize. Provides
push button circuit disconnection.

Dead Front Safety Shutter
Assures safety by preventing
user access to live parts.

1
Casing
Fiberglass reinforced thermoplastic polyester material
offers great resistance to
impact, corrosion and harsh
environmental conditions.

Spring Assisted Screw Terminals
Patented design assures “Tighten
and Forget” confidence.

When the plug and receptacle are latched together,
the circuit is connected.

Spring Loaded Butt-Style Contacts
Ensures optimal contact force and
superior electrical performance
over thousands of operations.

2

Lid

Silver-Nickel Contact Material

Provides additional
protection from harsh
environments.

Solid silver-nickel contact surfaces
provide superior conductivity, durability
and corrosion resistance.

Lockout-Tagout Provisions
Allows plug to be easily locked out and
tagged. Optional Padlock Pawl allows
lockout/tagout of the receptacle.

Pressing the pawl causes
the DECONTACTOR to
break the circuit. The
plug is ejected to its rest
position; its contacts are
now dead.

Rotating the ‘dead’ plug
30° counterclockwise
closes the safety shutter
and frees the plug to be
withdrawn from the
receptacle.

DSN Decontactors are UL & CSA rated for
“motor circuit” and “branch circuit” disconnect
switching – up to 20 hp and up to 60A

DSN20 devices are 480 VAC

** Testing was performed with RK1 current limiting fuses
sized at 400% or more of the highest full load motor
ampacity associated with the devices horsepower ratings.
