Littelfuse HCC Series Contactors
Littelfuse HCC Series 1- and 2-Pole 20-40FLA Definite Purpose Contactors utilize one wire to control the electrical current direction and are available with one pole normally open (NO), with or without a shunt, or with two poles NO. These contactors feature silver cadmium oxide contacts and #10-32 screw or box lug power pole terminations. Other features include a +130°C Class B insulation system and initial dielectric strength of 2200VAC between contacts and coils, between poles (includes shunt), and between open contacts (no shunt). Littelfuse HCC 1- and 2-Pole 20-40FLA Definite Purpose Contactors are typically used in residential applications.
Littelfuse HCC Series 3-Pole 50-60FLA Definite Purpose Contactors feature silver cadmium oxide contacts and three poles normally open (NO). These contactors utilize three wires to control the electrical current direction. They are in-house tested and validated and offer a +130°C Class B insulation system. Additional features include aluminum box lug power pole terminations, standard arc cover, and initial dielectric strength of 2200VAC between contacts and coils, between poles, and between open contacts. Littelfuse HCC 3-Pole 50-60FLA Definite Purpose Contactors are ideal for applications such as commercial HVAC, refrigeration, food and beverage, EV charging, and more.
