P50 Agile P15D
14 Technical Specifications
P15D/EN TM/B 14-5
III.
VA burden of Status S4 (Remote Trip) For 100 to 230 V AC nominal voltage range < 12 VA
For 100 to 230 V DC nominal voltage range < 4 W
For 24 V to 50 V DC nominal voltage range < 4 W
Note: P15D is not supplied from auxiliary supply and current is below the
minimum current required to power ON the relay. Relay draws power
from Remote Trip input to power ON and provide tripping output to CB
IV.
Operating voltage range 90% of lower nominal range and 120% of upper nominal range for DC
90% of lower nominal range and 110% of upper nominal range for AC

III.
Impulse Output for tripping coil Impulse output for the tripping
coil
12 V - 24 VDC (Energy <= 0.1 J)
Note: The trip energy for the trip coil is stored by a capacitor built into the protection relay. The capacitor is charged by a current
input or the auxiliary voltage. The duration of the trip pulse is 50 ms (if output is not burden). The pause between the individual pulses
depends on the impedance of the trip coil and on the current level. The pulse lasts as long as the activation threshold is exceeded. The
voltage level of the energy output depends on the discharging time

12 V - 24 VDC (Energy <= 0.03 J)
Note: The trip energy for the flag indicator is stored by a capacitor built into the protection relay. The capacitor is charged by a current input or the
auxiliary voltage. The duration of the trip pulse is 50 ms (if output is not burden). The pause between the individual pulses depends on the
impedance of the flag indicator and on the current level. The pulse lasts as long as the activation threshold is exceeded The impulse output for flag
indicator and trip coil drive energy from same source. The flag out use additional capacitor to store required energy. If more energy is take from
flag output than specified, then it will affect energy output of trip coil
