1SVR730784R3300 ABB Control Industrial Automation Components

ABB 1SVR730784R3300 is a control relay designed for phase failure, sequence, and under-/over-voltage monitoring for 3-phase systems with adjustable thresholds. It features phase failure detection, phase sequence monitoring, and ON-delay/OFF-delay trip timers. The relay has DPDT (Double Pole Double Throw) - 2C/O contacts, with a housing speed rating of IP50 and terminal speed rating of IP20. The control voltage is suitable for DIN rail mounting, and it operates with a control circuit rated current of 4 A at 230Vac for AC-12, 3 A at 230Vac for AC-15, and similarly rated for DC-12 and DC-13 applications at 24Vdc. It supports a wide range of wire sizes for both flexible and rigid wires, with specific AWG ratings provided. The supply voltage is rated at 400 V AC, with a frame current rating of 0.025 A at 400Vac. The relay's operational life is rated at 100,000 operations for mechanical endurance and 30,000,000 operations for electrical endurance. It features a yellow LED for control/supply voltage presence, a green LED for timer activity, and red LEDs for overvoltage and undervoltage detection. The tripping curve is adjustable from 0.1-30 seconds, and it utilizes screw-clamp terminals for connections. The relay operates within a temperature range of -25°C to +60°C and has a short circuit current breaking capacity (Icn) suitable for its rated applications. The relay's net height and width are specified in mm, and it is designed to replace products with silver-nickel alloy contacts that are cadmium-free.
