1SVR730840R0500 ABB Control Industrial Automation Components

ABB 1SVR730840R0500 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 communication protocol measures 85.6 mm, with a net height of 4 kV, rated impulse voltage (Uimp) of 22.5 mm, and a rated insulation voltage (Ui) of 600 V. Its dimensions include a net width of 103.7 mm. The control voltage is suitable for DIN rail mounting, and it supports various wire types and sizes for Normally Closed (NC) auxiliary contacts. The relay operates within a supply voltage range of AC/DC 24-240 V and is designed for 100,000 operations, with the contacts made from a Silver-Nickel alloy (Ag / Ni) for up to 30,000,000 operations. Indicators include a green LED for control/supply voltage presence, a flashing green LED for timer activation, a red LED for overcurrent/undercurrent detection, and a steady yellow LED when the output relay is energized. The tripping curve is adjustable from 0.1-30 s, with screw-clamp type terminals. It operates within a temperature range of -20°C to +60°C, with a control circuit rated current of 4 A at 230Vac, AC-12, and 3 A at 230Vac, AC-15. The short circuit current breaking capacity (Icn) is 4 A at 24Vdc, DC-12, and 2 A at 24Vdc, DC-13. The relay offers protection settings and measurement functions for operating currents of 0.3-1.5A, 1-5A, and 3-15A.
