1SVR730840R0200 ABB Control Industrial Automation Components

ABB 1SVR730840R0200 is a current monitoring relay designed for single-phase under-/over-current monitoring with a SPDT (Single Pole Double Throw) - 1C/O contact type. It features a housing speed of IP50 and terminal speed of IP20. The communication protocol measures at 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. The dimensions include a net width of 103.7 mm. It is designed for DIN rail mounting and supports a control voltage (AC) with normally closed (NC) auxiliary contacts accommodating various wire sizes and types. The relay operates within a supply voltage range of 24-240 V (AC/DC) and is rated for 100,000 operations, with the contacts made from a Silver-Nickel alloy (Ag / Ni). It offers analog outputs for up to 30,000,000 operations. The device indicates its status through a green LED for control/supply voltage presence, a red LED for overcurrent/undercurrent, and a yellow LED when the output relay is energized. The trip unit type is screw-clamp, and it operates within a temperature range of -20°C to +60°C. The control circuit rated current is 4 A for AC-12 at 230Vac, 3 A for AC-15 at 230Vac, and for DC, 4 A for DC-12 and 2 A for DC-13 at 24Vdc. It features a short circuit current breaking capacity (Icn) and adjustable protection settings. The operating rate for measurement functions ranges from 3-30mA, 10-100mA, to 0.1-1A.
