Welcome to G-TV! Today I would like to show you Joslyn Clark 5DP Series Definite Purpose
contactors. The 5DP Definite Purpose Contactors are designed for DC adjustable speed drive
circuits using silicon controlled rectifier switching and other controls where a combination
of normally open and normally closed power contacts are required. In all applications,
reduced panel space for contactor mounting is made possible through a compact design
and the built-in normally closed dynamic brake power contact feature. Contacts are made of
a silver cadmium oxide furnish "anti-weld" protection under overload conditions. Generous
size contacts are long lasting, and maintenance-free. All normally closed contacts are supplied
with permanent magnet blowouts to lengthen contact life. Permanent magnet blowouts can
also be available on the normally open contacts. These permanent magnet blowouts are mounted
to surround the power contact and function to quickly quench the arc when breaking loads,
ensuring a positive load circuit interruption. The springs are stainless steel and maintain
exact contact pressure and assure fast contact make and break. The Housing is constructed
of hot-molded, high impact, high arc resistant insulating material. This design totally encloses
the contacts and operating magnet in separate compartments and functions to eliminate internal
phase-to-phase short circuits. Joslyn Clark's 5DP Series Definite Purpose contactors along
with thousands of other products and services are available at galco.com.
