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.

The plug and the receptacle

are separated. The safety

shutter prevents access to

live parts.

Rotating the ‘dead’ plug

30° counterclockwise

closes the safety shutter

and frees the plug to be

withdrawn from the

receptacle.

When the plug and recep-

tacle are latched together,

the circuit is connected.

Pressing the pawl causes

the DECONTACTOR to

break the circuit. The

plug is ejected to its rest

position; its contacts are

now dead.

To reconnect, insert

plug into receptacle,

rotate 30° clockwise, and

apply insertion force.
