Max. DC load breaking capacity

Load limit curve 1: arc extinguishes, during transit time (changeover contact).

Load limit curve 2: safe shutdown, no stationary arc (make contact).

Load limit curves measured with low inductive resistors verified for 1000 switching events.

1) The values apply to a resistive or inductive load with suitable spark suppression and at

maximum 13.5VDC for 12VDC load voltages. For a load current duration of maximum

3s for a make/break ratio of 1:10.

2) Corresponds to the peak inrush current on initial actuation (cold filament).

3) See chapter Diagnostics of Relays in our Application Notes or consult the internet at

http://relays.te.com/appnotes/

4) Measured at nominal voltage without coil suppression unit. A low resistive suppression

device in parallel to the relay coil increases the release time and reducesthe lifetime

caused by increased erosion and/or higher risk of contact tack welding.

5) Be aware of using right polarity, see Terminal Assignment. Wrong polarity will reduce

endurance.
