HFA100 - Multicontact Auxiliary Relays

HFA Century Series relays are designed for applications where a number of auxiliary functions must be performed simultaneously.

The Century Series coil design provides longer operating life than previeous designs as a result of changes in the entire coil insulation system.

• of HFA Century series coils are as follows: Spool The spool on which this coil is wound is made of high thermal strength, glass-filled polyester to obtain long life at elevated temperatures. This material shows no signs of cracking or brittleness under accelerated life testing. Wire Insulation The wire insulation is a polyamide-imide wire coating (180° C rating) which retains insulation integrity and mechanical strength at continuous elevated temperatures and which is also non-hydroscopic and fu.
