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. 6 operations per minute for rated life at rated load. Max. Switching Voltage: 75VDC(1). Max. Load Current (@ 14VDC Load Voltage): 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. 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). Weight: 31g (1.1 oz.) approximately (dust cover model). Load Max. Continuous Current Max. Make Current (2) Max. Break Current (1) Form A (NO) 60A 120A 60A Form C NO 60A 120A 60A NC 40A 45A 40A Max. Switching Power: 50-500 watts DC (voltage dependent) (1). Min. Recommended Current: 1 amp @ 12VDC. 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 Between Contacts and Coil: 500V rms. Notes (1) See Figure
- (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. (4) See Figure
- (5) Current and times are compatible with circuit protection by a typical automotive circuit breaker. Relay will make, carry and break the specified current. 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. 1.81W, with 680 ohm resistor. Thermal Resistance: 50°C per actual coil watt in still air with no contact load current.
