DCR and Impedance based on 100% rated current applied and stabalized for
a minimum of one hour. Tolerance .05-2.5 amperes ± 20%: 2.6 -20 amperes
± 25%, 21-50 amperes ± 50%. Consult factory for special values and for coil
impedance of delays not shown.
OPERATING CHARACTERISTICS
Inrush Pulse Tolerance
The following table provides a comparison of inrush
pulse tolerance with and without the inertial delay
feature for each of the 50/60Hz delays. 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 at left provides a guide to determine if the
inertia delay feature is required. Consult factory for
further assistance.
