1SVR740884R1300 ABB Control Industrial Automation Components

ABB 1SVR740884R1300 is a multifunctional monitoring relay designed for 3-phase control with features including phase failure detection, phase sequence monitoring, and ON-delay / OFF-delay trip timers. It is equipped with DPDT (Double Pole Double Throw) - 2C/O contacts, offering a housing speed of IP50 and terminal speed of IP20. The communication protocol measures at 85.6 mm, with a net height of 4 kV and a rated impulse voltage (Uimp) of 22.5 mm. This relay is capable of detecting overvoltage, undervoltage, and phase unbalance with a rated insulation voltage (Ui) of 600 V and a control voltage for DIN rail mounting at (230Vac) 10 VA. It supports both flexible and rigid wires ranging from 0.5-1.5mm2 or 20-16AWG. Operating at a wavelength of 50/60 Hz, it has a supply voltage for up to 100 000 operations, with Normally Closed (NC) circuits rated at 300 V. The product's contacts are made from a Silver-Nickel alloy (Ag / Ni) and are cadmium-free (Cd-free), ensuring a long operational life of 30 000 000 operations. The frame current rating at (230Vac) is 0.025 A with a tripping curve of 0.1-30 s and 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 and 3 A for AC-15 at (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 performance, with an operating rate of (L-L) 160-300Vac.
