(2) Inrush current for lamp load.
(3) Allowable overdrive is rated at ambient temperature for 23°C or 85°C as
stated with no load current flowing through the relay contacts and
minimum coil resistance. Also see Figure 2 for maximum ambient
temperature versus applied coil voltage.

(5) Current and times are compatible with circuit protection by a typical
automotive circuit breaker. Relay will make, carry and break the
specified current.
