1SVR730831R0300 ABB Control Industrial Automation Components

ABB 1SVR730831R0300 is a control relay designed for voltage monitoring in single-phase systems. It features a voltage monitoring relay with under-/over-voltage protection functions and a SPDT (Single Pole Double Throw) contact type, offering 1 Changeover (C/O) contact. The housing is rated at IP50, while the terminals are rated at IP20 for protection. The control voltage is suitable for DIN rail mounting, and it supports a variety of wire types and sizes for flexible and rigid wires, including specifications from 0.5-4mm2 and 18-12AWG. The relay operates within a supply voltage range of AC 110-130 V and has a rated insulation voltage (Ui) of 600 V, with a rated impulse voltage (Uimp) of 4 kV. The net height and width are 103.7 mm and 22.5 mm, respectively, indicating its compact size. 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) for improved performance. It includes three LED indicators: green for control/supply voltage presence, red for overvoltage/undervoltage, and yellow for output relay energization. The trip unit type is a screw-clamp for secure connections, and it operates within a temperature range of -20°C to +60°C. The control circuit rated current varies with the application, from 4 A in AC-12 and DC-12 settings to 2 A in DC-13 settings. The relay offers multiple protection settings and an operating rate for different voltage ranges: 3-30V, 6-60V, 30-300V, and 60-600V, ensuring versatility in monitoring and protection tasks.
