1SVR730841R0500 ABB Control Industrial Automation Components

ABB 1SVR730841R0500 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 and 2 x 0.5-1.5mm2 for flexible wires, and 1 x 0.5-4mm2 and 2 x 0.5-2.5mm2 for rigid wires, among others. The supply voltage operates at AC 110-130 V, designed for 100,000 operations, with a replacement product made from Silver-Nickel alloy (Ag / Ni). It offers analog outputs for 30,000,000 operations. The device includes indicators: a green LED for control/supply voltage presence, a flashing green LED for timer activation, a red LED for overcurrent/undercurrent, and a steady yellow LED when the output relay is energized. The tripping curve ranges from 0.1-30 s, with a screw-clamp type of terminals. It operates within a temperature range of -20°C to +60°C, with a control circuit rated current of 4 A at 230Vac for AC-12, 3 A at 230Vac for AC-15, and 4 A at 24Vdc for DC-12, and 2 A at 24Vdc for DC-13. The protection settings include a short circuit current breaking capacity (Icn) and measurement functions for operating rates of 0.3-1.5A, 1-5A, and 3-15A.
