Max. DC load breaking capacity
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) Current and time are compatible with circuit protection by a typical automotive fuse.
Relay will make, carry and break the specified current.
4) See chapter Diagnostics of Relays in our Application Notes or consult the internet at
http://relays.te.com/appnotes/
5) Electrical endurance data are only valid for the variants with resistor.
6) Not applicable for polarity reverse loads like powerwindows
Load limit curve 1: arc extinguishes during transit time (CO contact).
Load limit curve 2: safe shutdown, no stationary arc (NO contact).
Load limit curves measured with low inductive resistors verified for 1000 switching events.
