NEMA Rated AC Clapper Style Magnetic Contactors
(See Type 5210 for DC Contactors)
Size 3 Normally Open Shown
contactors feature many unique design and engineering advancements that greatly
simplify applications, installations and servicing. Decades of
experience in design as well as manufacturing has been incorporated into these
highly reliable units.
The Contactor line uses the latest technology in molded plastic materials for
those parts requiring insulating qualities and strength.
Completely front-connected, front removable "deadback" base design
eliminates all nuts and bolts as well as live parts on the back making these
contactors suitable for steel panel mounting. There is easy front access to
every part of the contactor for ease of inspection and maintenance.
Available in NEMA sizes 1 through 8, Single, Two, and Three Pole configurations.
Convenient DIRECT-WIRING for Right or Left Hand Power Connections. Rugged
Terminals on both sides of the Power Poles for all power connections (NEMA
sizes 3 through 8).
Encapsulated 115 or 230 V.DC operating coils (standard), for long
Corrosion resistant, durable, welded steel construction armature assembly
incorporates stainless steel spring as well as stainless steel hinge pin
providing long mechanical life
Auxiliary Electrical Contact block can be mounted on either the right or
left hand side of the Power Pole. Contacts are bridge-type, double-breaking,
silver-cadmium oxide. Units can be "stacked" two deep, for multi-circuit
arrangements. Auxiliary Electrical Contacts are supplied in kit form
consisting of one or two contact blocks each housing one(1) normally open and
one (1) normally closed set of contacts, one knocker, plus the necessary
Hinged Arc-Shield for easy inspection and
replacement of contactor tips.
Efficient dynamic blow-out coils on the power poles affords unusually high
arc rupturing capacity.
Selection of main contact tip materials, hard-drawn copper (standard),
silver-cadmium oxide, or silver-tungsten- carbide.
All bearings consist of stainless steel pins working in oversize
self-lubricating powered metal bronze bushings.
- Long life results from the low-inertia design and DC power-plant which
provide fast-action without destructive hammering.
Rugged welded, pressed steel construction coupled with an efficient DC
power plant and arc rupturing assembly has given these mill-duty contactors an
enviable service life.
Most parts are interchangeable with Type 5210, DC contactors.
