1) The values apply to a resistive or inductive load with suitable spark suppression and
at maximum 14VDC for 12VDC or 28VDC for 24VDC load voltages. For a load current
duration of maximum 3s for a make/break ratio of 1:10.
2) Current and time are compatible with circuit protection by a typical automotive fuse.
Relay will make, carry and break the specified current.
3) See chapter Diagnostics of Relays in our Application Notes or consult the internet at
http://relays.te.com/appnotes/
4) 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.
