55 Series - General purpose relays 7 - 10 A
F 55 - Electrical life (AC) v contact current
2 and 3 pole relays
Cycles
DC voltage (V)
DC breaking current (A)
H 55 - Maximum DC1 breaking capacity
• When switching a resistive load (DC1) having voltage and current
values under the curve, an electrical life of ≥ 100·10
3
can be expected.
• In the case of DC13 loads, the connection of a diode in parallel with
the load will permit a similar electrical life as for a DC1 load.
Note: the release time for the load will be increased.
