1SVR730840R0700 ABB Control Industrial Automation Components

ABB 1SVR730840R0700 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 includes an ON-delay trip timer and features DPDT (Double Pole Double Throw) - 2C/O contacts. The housing is rated at IP50 and terminals at IP20 for protection. It has a communication protocol width of 85.6 mm, a net height of 4 kV for rated impulse voltage (Uimp), a protection function rating of 600 V for rated insulation voltage (Ui), and a total length of 103.7 mm. The control voltage is suitable for DIN rail mounting, and it supports various wire sizes for Normally Closed (NC) auxiliary contacts, ranging from 0.5-4mm2 for rigid wires and 18-12AWG for flexible wires. It operates on a supply voltage 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 enhanced durability up to 30,000,000 operations. The net width is indicated by a series of LED indicators for different statuses: green LED for control/supply voltage presence, flashing green LED for timer activation, red LED for overcurrent/undercurrent detection, and steady yellow LED for output relay energization. It offers a tripping curve of 0.1-30 s and utilizes screw-clamp terminals. The minimum operating temperature is -20°C, and it can handle 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. The maximum temperature it can withstand is +60°C, with protection settings allowing for an operating rate of 0.3-1.5A, 1-5A, and 3-15A for precise current monitoring.
