1SVR730794R3300 ABB Control Industrial Automation Components

ABB 1SVR730794R3300 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 communication protocol measures 85.6 mm, with a net height of 4 kV and a rated impulse voltage (Uimp) of 22.5 mm. It supports overvoltage and undervoltage protection functions with a rated insulation voltage (Ui) of 600 V and a control voltage for DIN rail mounting at (400Vac) 18 VA. The relay accommodates various wire sizes for both flexible and rigid wires, operates at a wavelength of 50/60 Hz, and has a supply voltage for 100,000 operations. The number of Normally Closed (NC) circuits is rated at 500 V. This product, which uses a Silver-Nickel alloy (Ag/Ni) and is cadmium-free (Cd-free), has an analog output of 30,000,000 operations. The frame current rating is (400Vac) 0.025 A, with indicators including 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 ranges from 0.1-30 s, with screw-clamp terminals. It operates within a temperature range of -25°C to +60°C, has a control circuit rated current of (230Vac, AC-12) 4 A, and a short circuit current breaking capacity (Icn) suitable for various AC and DC applications. The protection settings and measurement function ensure operation within (L-L) 300-500Vac.
