DC Delay Curves (typ)
10000
A choice of delays is offered for DC applications.
Delays 50 and 59 provide fast acting, non-delayed
tripping to protect sensitive electronic equipment
(not recommended where known inrush exists).
Delay 51 has a short delay for general purpose
applications. Delay 52 is long enough to start certain
types of motors. Delay 53 is an extra long delay used
primarily for special motor applications.
