1SVR740885R1300 ABB Control Industrial Automation Components

ABB 1SVR740885R1300 is a multifunctional monitoring relay designed for both single-phase and 3-phase applications. It features phase failure detection, phase sequence monitoring, interrupted neutral 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 suited for DIN rail mounting, and it supports a communication protocol width of 85.6 mm. Its net height is 4 kV, with a rated impulse voltage (Uimp) of 22.5 mm. The relay offers protection functions against overvoltage, undervoltage, and phase unbalance detection, with a rated insulation voltage (Ui) of 600 V and a total height of 103.7 mm. It operates with a control voltage (AC) of 115Vac consuming 10 VA, and accommodates both flexible and rigid wires ranging from 0.5-1.5mm2 or 20-16AWG. The relay functions at a wavelength of 50/60 Hz, with a supply voltage for AC operations at 170 V, and a rated voltage (AC) - Phase-to-phase of 170 V. It is designed to replace products with contacts made of Silver-Nickel alloy (Ag / Ni) and is cadmium-free (Cd-free). The analog outputs are rated for 30 000 000 operations, with a frame current rating at (115Vac) 0.025 A. The tripping curve ranges from 0.1-30 s, with a trip unit type of spring. The minimum operating temperature is -25°C, and the maximum is +60°C. The control circuit rated current is 4 A for AC-12 (230Vac) and 3 A for AC-15 (230Vac), with a DC-12 and DC-13 rating of 4 A and 2 A respectively at 24Vdc. The short circuit current breaking capacity (Icn) and protection settings are designed for robust operation, with a processing time and measurement function optimized for efficiency in a wide range of industrial applications.
