Appendix B Relay Contact Ratings - GE VersaMax Manual

Relay Contact Ratings
Appendix
B
Mechanical Rating
Relay contacts are rated for 10
Electrical Rating
The relay contact use in VersaMax modules meet Underwriters Laboratories' Pilot Duty
Rating for Control Circuits. Contact life depends on type of load and current, as
summarized in the table below.

Power Factor = 0.4 minimum for AC inductive loads
Time Constant – 7mS for DC inductive loads
Installing suitable suppression across inductive loads enhances reliability. For DC, a free-
wheeling diode provides suitable suppression. For AC, an R-C filter can be used.
