1SVR730840R0600 ABB Control Industrial Automation Components

ABB 1SVR730840R0600 is a current monitoring relay designed for single-phase under-/over-current monitoring with a latching feature and operates on both open circuit and closed circuit principles. It features a DPDT (Double Pole Double Throw) contact type, with a housing protection speed of IP50 and terminal protection speed of IP20. The control voltage is suitable for DIN rail mounting, and it accommodates various wire sizes for flexible and rigid wires, with specific capacities for Normally Closed (NC) auxiliary contacts. The supply voltage ranges from AC/DC 24-240 V, and it is designed for a high number of operations, with the contacts made from a Silver-Nickel alloy (Ag / Ni). The relay provides visual feedback 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 steady yellow LED when the output relay is energized. It offers a tripping curve of 0.1-30 seconds and utilizes screw-clamp terminals. The relay operates within a temperature range of -20°C to +60°C, supports control circuit rated currents of 4 A for AC-12, 3 A for AC-15 at 230Vac, and 4 A for DC-12, 2 A for DC-13 at 24Vdc, with short circuit current breaking capacities accordingly. The protection settings are adjustable for currents ranging from 3-30mA, 10-100mA, to 0.1-1A, ensuring versatile application across different monitoring needs.
