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

Inrush Pulse Tolerance
Pulse tolerance is defined as a single pulse of half sine wave
peak current amplitude of 8 milliseconds duration that will
not trip the circuit breaker.
The table on page 171 provides a guide to determine if the
inertia delay feature is required. Consult factory for further
assistance.
