current inputs, IA, IB, IC)
51P1C
51P2C
curve type U1 - U5 (US curves), C1 - C5 (IEC curves),
recloser or user curves
see Figure 9.1 - Figure 9.20
51P1TD
51P2TD
time dial (has no multiplying
effect on constant time adder
or minimum response time)

Y, N
51P1CT
51P2CT
constant time adder – adds
additional time to curve
0.00 - 60.00 cycles
(no effect if set = 0.00)
51P1MR
51P2MR
minimum response time –
flattens curve at set time;
curve can operate no faster
than this set time
0.00 - 60.00 cycles
(no effect if set = 0.00)
51P1TC
