1SVR730760R0400 ABB Control Industrial Automation Components

ABB 1SVR730760R0400 is a current monitoring relay designed for single-phase applications. It features current monitoring with a window function, latching capabilities, and operates on both open circuit and closed circuit principles. The relay includes an ON-delay and OFF-delay trip timer and is equipped with DPDT (Double Pole Double Throw) contacts. It has a housing protection rating of IP50 and terminal protection rating of IP20. The control voltage is suitable for DIN rail mounting, and it accommodates various wire sizes for 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 ranges from AC/DC 24-240 V, and it is designed for a high number of operations, with 100,000 operations for mechanical endurance and 30,000,000 for electrical endurance. The relay's contacts are made from a Silver-Nickel alloy (Ag / Ni). It features a green LED for control/supply voltage indication, a flashing green LED for timer activation, a red LED for overcurrent/undercurrent detection, and a yellow LED to indicate when the output relay is energized. The tripping curve is adjustable from 0.1-30 seconds, and it uses screw-clamp terminals. The control circuit rated current is 4 A for AC-12 at 230Vac, 3 A for AC-15 at 230Vac, and 4 A for DC-12 at 24Vdc, with a short circuit current breaking capacity (Icn) of 2 A for DC-13 at 24Vdc. The operating temperature ranges from -20°C to +60°C, and it offers protection settings and measurement functions for currents ranging from 3-30mA, 10-100mA, to 0.1-1A.
