1SVR750487R8300 ABB Control Industrial Automation Components

ABB 1SVR750487R8300 is a multifunctional monitoring relay designed for 3-phase applications. It features phase failure detection, phase sequence monitoring, automatic phase sequence correction, and ON-delay / OFF-delay trip timers. The relay has DPDT (Double Pole Double Throw) contacts, which are configurable as 2 x 1C/O or 1 x 2C/O. The housing is rated IP50, and the terminals are rated IP20. It supports a control voltage of 480Vac with a power consumption of 41 VA. The relay accommodates flexible and rigid wires with various AWG sizes for Normally Closed (NC) auxiliary contacts. It operates at a frequency of 50/60 Hz and has a supply voltage rating for NC circuits of 580 V. The product is designed to replace silver-nickel alloy (Ag / Ni) and is cadmium-free (Cd-free). It has an analog output operational life of 30,000,000 operations and a frame current rating at 480Vac of 0.029 A. The tripping curve is adjustable from 0.1-30 s, and it utilizes screw-clamp terminals. The control circuit rated current is 4 A at 230Vac for AC-12 applications and 3 A at 230Vac for AC-15 applications, with a short circuit current breaking capacity (Icn) for DC-12 and DC-13 applications at 4 A and 2 A respectively at 24Vdc. The relay operates within a temperature range of -25°C to +60°C and has an operating rate for L-L measurements of 350-580Vac.
