1) The values apply to a resistive or inductive load with suitable spark suppression and at maximum 13.5VDC for 12VDC or 27VDC for 24VDC load voltages.
2) For a load current duration of maximum 3s for a make/break ratio of 1:10.
3) Corresponds to a peak inrush current on initial actuation (cold filament).
4) See chapter Diagnostics of Relays in our Application Notes or consult the internet at http://relays.te.com/appnotes/
5) For unsuppressed relay coil. A low resistive suppression device in parallel to the relay coil increases the release time and reduces the lifetime caused by increased erosion and/or higher
risk of contact tack welding.

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.
