Application:
NEMA heavy duty contactors and starters are designed for across the
line starting of 3 phase motors. Typical applications include cooling
owers, refrigeration equipment, and commercial HVAC. NEMA
t
contactors provide the switching (on/off) function. NEMA starters
consist of a NEMA contactor with the addition of motor protection via
a solid state overload relay which includes phase loss protection.
Standard NEMA Contactor Features:
Rugged Industrial Design
•
Epoxy encapsulated coil seals out moisture, promotes heat transfer,
and resists electrical, mechanical, and thermal stresses. The 45 degree
wedge action contacts reduce tracking and provide faster arc
quenching. The resulting self-cleaning and reduced contact bounce
mean cooler operation and longer life for the large silver cadmium
oxide contacts
• Dual Voltage Coils
120/240 VAC is standard
24 VAC and 240/480 VAC are available as accessories
• Easy Coil Access
Top mounted coil requires no tools to change
