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

Pick up voltage range

For 100 to 230 V aux. supply : 60 – 80V
For 24 to 50 V aux. supply : 15 – 19V

VI.

Drop off voltage range

For 100 to 230 V aux. supply : 30 – 60V
For 24 to 50 V aux. supply : 7 – 15V

VII.

-50 W Inductive (L/R =45 ms) max.

5A or 300 V

Operating Time

<10 msec

Minimum no. of operations

unloaded 100,000 operations

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

IV.

Impulse Output for Flag Indicator or Auxiliary Relay Impulse

output

for

Flag

Indicator or auxiliary Relay

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
