"Three Auxiliary Contact" 30 Amp Unfused
Disconnect Switch “Suitable as Motor Disconnect”
Hubbell’s new “Three Auxiliary Contact” 30 Amp
Unfused Disconnect Switch is the latest addition to
the Circuit-Lock® family of switched enclosures. It
provides maximum flexibility for control circuit and
signal applications including switching for PLCs and
electronic drive systems. Auxiliary contacts are factory
installed and ready for wiring. The switch includes both
(Early Break) Break Before Main Break contacts,
(1 set “normally open” 1 set “normally closed” and
(Normal Break) Break After Main Break contacts,
(2 sets “normally open” 1 set “normally closed”). The
switch wiring diagram illustrated below is included in
each switch enclosure for convenient reference.
Meets NEC® Requirements
Hubbell’s Circuit-Lock® unfused disconnect switches
are UL listed as a manual motor controller and also
“suitable as a motor disconnect.” They meet NEC®
Section 430.102(b), requiring each motor controller to
have a disconnect within line of sight from the motor
and driven equipment.
Performance Proven
Impact/chemical resistant Valox® construction provides
superior performance in harsh environments subject to
wash down, dirt and corrosion. Non-metallic enclosure
meets UL 50 Type 4X (watertight, wash down) 12K dust
tight and IP66 suitability requirements.
