55 Series - Miniature General Purpose Relays 7 -10 A
CONTACT SPECIFICATIONS
Breaking capacity for DC1 load.
1 = 2 - 3 CO type.
2 = 4 CO type.
A = Load applied to 1 contact
B = Load applied to 2 contacts in series
C = Load applied to 3 contacts in series
D = Load applied to 4 contacts in series
• When switching a resistive load (DC1) having voltage and
current values under the curve the expected electrical life is
≥ 100·10
3
cycles.
• In case of DC13 loads the connection of a diode in parallel with
the load will permit the same electrical life as for a DC1 load.
Note: the release time of load will be increase.
Electrical life vs AC1 load.
1 = 4 CO relay type (7 A).
2 = 2 - 3 CO relay type (10 A).
