40 Amp Relay
With PC Board or
Quick Connect Terminals
for Automotive Applications
Users should thoroughly review the technical data before selecting a product part
number. It is recommended that users also seek out the pertinent approvals files of
the agencies/laboratories and review them to ensure the product meets the
requirements for a given application.
Features
Operate Data
• 40A continuous contact rating @ 85°C.
• 1 Form A and 1 Form C arrangements.
• Plug-in or PC board terminals.
• Optional mounting bracket.
Must Operate and Must Release Voltage: See Coil Data table.
Initial Operate Time: 7 milliseconds, typical, with rated coil voltage
applied.
Initial Release Time: 2 milliseconds, typical, with zero volts applied (for
unsuppressed relays after having been energized at
rated coil voltage.)
• Various enclosure options.
Environmental Data
Temperature Range: Storage: -40°C to +155°C.
Conditions
(4)

Shock: 20g, 11 milliseconds, half sine wave pulse.
.
All parametric, environmental and life tests are performed according to EIA
Standard RS-407-A at standard test conditions (23°C Ambient, 20-50% RH,
29.5 1.0" Hg.) unless otherwise noted.
Vibration: (For NC contacts, NO contacts are significantly higher.)
10-40 Hz., 1.27mm double amplitude.
40-70 Hz., 5 g's constant.
70-100 Hz., 0.5mm double amplitude.
100-500 Hz., 10 g's constant.
Contact Data
Arrangements: 1 Form A (SPST-NO) and 1 Form C (SPDT).
Material: AgNi 0.15 (consult factory for other contact materials).
Max. Switching Rate: 20 operations per second with no contact load.
Mechanical Data
Termination: 0.250" quick connect and printed circuit terminals.
Enclosures:
Dust Cover: Protects relay from dust. For use in passenger
compartment or enclosures.

.
Max. Switching Voltage: 75VDC
Max. Load Current (@ 14VDC Load Voltage):
Shrouded Dust Cover: Protects relay and relay connector (order
separately) from dust and splash.
Weatherproof Cover: Mates with a connector (order separately) to seal
relay from salt spray etc. Recommended for under
hood application.
Cover Retention: Dust cover will withstand a 33.7 pound (150 Newton)
force (axially applied) without detachment. Ultrasonic
cover: 50 pound (220 Newton).

Max. Switching Power: 50-500 watts DC (voltage dependent)
Min. Recommended Current: 1 amp @ 12VDC.
Weight: 31g (1.1 oz.) approximately (dust cover model).
Initial Voltage Drop: 200 millivolts, maximum, for normally open contacts
@ 40 amp contact load.
250 millivolts, maximum, for normally closed
contacts @ 30 amp contact load.
Expected Life: 10 million operations, mechanical; 100,000 operations at 40
amps, 14VDC, resistive load on normally open contact.
Abnormal Operation
Overload Current: Consult factory.
24V Jump Start: 24VDC for 5 minutes conducting rated contact current
@ 23°C.
Drop Test: Capable of meeting specifications after a 3.28 foot (1.0 meter)
drop onto concrete.
Flammability: UL94V-0 external; UL94-HB or better, internal parts (meets
FMVSS 302).
Initial Dielectric Strength
Notes
Between Contacts and Coil: 500V rms.

(2) Inrush current for lamp load.
Coil Data
Voltage: 6, 12 and 24VDC.
Resistance: See Coil Data table.
Nom. Power: (@ 23°C coil temp. and rated coil voltage.):
1.6W, unsuppressed.
(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.
(4) See Figure 2.
1.81W, with 680 ohm resistor.
(5) Current and times are compatible with circuit protection by a typical
automotive circuit breaker. Relay will make, carry and break the
specified current.
Thermal Resistance: 50°C per actual coil watt in still air with no contact
load current.
