Example: An LC1-F185 contactor supplied with 115 V/50 Hz for a consumption of 55 VA or a current consumption equal to 0.1 A and cos ϕ = 0.3. For 0.1 A, curve 1 indicates a durability of approximately 1.5 million operating cycles. As the load is inductive, it is necessary to apply a reduction coefficient k to this number of cycles as indicated by curve 2. For cos ϕ = 0.3: k = 0.6 The electrical durability therefore becomes:1.5 106 operating cycles x 0.6 = 900 000 operating cycles.D. C.

Technical DescriptionFunction K: Delay on De-Energisation (Without Auxiliary Supply)Description
On energisation, the output(s) R close(s). On de-energisation, timing period T starts and, at the end of this period, the output(s) R revert(s) to its/their initial state.2If the device has been stored, de-energised, for more than a month, it must be energised for about 15 seconds in order to activate it. Subsequently, it only takes 1 second to start the time delay.
UNEXPECTED EQUIPMENT OPERATION
If the time is not complied with, the relay remains energised indefinitely.
Failure to follow these instructions can result in death, serious injury, or equipment damage.Legend
