<strong>IELR</strong> DELAY CURVES<br />
400Hz, DC, 50/60Hz Delay Curves (typ)<br />
A choice of delays is offered for DC, 50/60Hz, 400Hz, or combined<br />
DC/50/60Hz applications. Delays 49, 59, 69 and 79 provide fast<br />
acting, instantaneous tripping and are often used to protect<br />
sensitive electronic equipment (not recommended where a<br />
known inrush exists). Delays 41, 51, 61 and 71 have a short delay<br />
for general purpose applications. Delays 42, 52, 62 and 72 are<br />
long enough for most transformers and capacitor loads. Delays<br />
43, 53, 63 and 73 are extra long for special motor applications.<br />
