Technical Description
RE8TA11BU
Function A: Delay on Energisation
Description
The timing period T begins on energisation. After timing, the output(s) R close(s). The second output can be either timed or instantaneous.
Function: 1 Output
Function: 2 Outputs
2 timed outputs (R1/R2) or 1 timed output (R1) and 1 instantaneous output (R2 inst.)

Performance Curves
A.C. Load Curve 1
Electrical durability of contacts on resistive loading millions of operating cycles
X Current broken in A
Y Millions of operating cycles
A.C. Load Curve 2
Reduction factor k for inductive loads (applies to values taken from durability curve 1).
X Power factor on breaking (cos ϕ)
Y Reduction factor k
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 10 6 operating cycles x 0.6 = 900 000 operating cycles.
