Technical specifications
B.2.1
Typical values for the closing coils
* Optional voltage
R1: resistor to be inserted in the holding circuit of the E type; the power to be considered for the
resistor choice is 220 W (4x55 W).
Rs: resistor to be inserted in serial with the coil in the opening circuit of the M type; the power to
be considered for the resistor choice is 50 W (200 W / 4).
Rp: resistor to be inserted in parallel with the closing coil in the opening circuit of the M type.
Notes
•
Values given for ambient temperature range between -30°C and 70°C. The I
max
and I
min
values are given for the most unfavourable values of voltage and temperature.
•
R

= 0.92 x R
nom
; R
max
= 1.08 x R

.
•
These values refer to DC voltage or rectified full-wave voltage.
•
The total opening time with a recovery diode is 2.5 s (not recommended as the opening time
is too long).
•
Sécheron recommends to protect the control circuit (while opening) with a varistor.
