1SVR730841R1500 ABB Control Industrial Automation Components

ABB 1SVR730841R1500 is a current monitoring relay designed for single-phase under-/over-current monitoring with an ON-delay trip timer. It features DPDT (Double Pole Double Throw) - 2C/O contacts, with a housing protection speed of IP50 and terminal protection speed of IP20. The control voltage is suited for DIN rail mounting, and it accommodates various wire sizes for both flexible and rigid wires, including 1 x 0.5-2.5mm2, 2 x 0.5-1.5mm2 for flexible wires, and 1 x 0.5-4mm2, 2 x 0.5-2.5mm2 for rigid wires, among others. The supply voltage is rated for AC 220-240 V, with a rated insulation voltage (Ui) of 600 V and a rated impulse voltage (Uimp) of 4 kV. The product's net height and width are 103.7 mm and 22.5 mm, respectively, and it supports 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. It features a short circuit current breaking capacity (Icn) and offers protection settings across a range of operating currents from 0.3-1.5A, 1-5A, to 3-15A. The tripping curve is adjustable from 0.1-30 s, and it includes a screw-clamp type of terminals. The operating temperature ranges from -20°C to +60°C. The relay provides visual status indicators through a green LED for control/supply voltage presence, a flashing green LED for timer activation, a red LED for overcurrent/undercurrent detection, and a yellow LED when the output relay is energized.
