1SVR730841R1400 ABB Control Industrial Automation Components

ABB 1SVR730841R1400 is a current monitoring relay designed for single-phase under-/over-current monitoring with an ON-delay trip timer. It features DPDT (Double Pole Double Throw) - 2C/O contacts, with a housing protection speed of IP50 and terminal protection speed of IP20. The communication protocol measures 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 control voltage (AC), with normally closed (NC) auxiliary contacts accommodating various wire sizes and types. The supply voltage is rated for (AC) 220-240 V, with a durability of 100 000 operations for the relay and 30 000 000 operations for the contacts, made from a Silver-Nickel alloy (Ag / Ni). The device features a green LED for control/supply voltage indication, a flashing green LED for timer activity, a red LED for overcurrent/undercurrent detection, and a steady yellow LED when the output relay is energized. The tripping curve is adjustable from 0.1-30 s, with screw-clamp terminals, and operates within a temperature range of -20°C to +60°C. The control circuit rated current varies with voltage and application, including AC-12, AC-15, DC-12, and DC-13 ratings, with specific amperages for each. The short circuit current breaking capacity (Icn) and protection settings are designed for robust operation, with a processing time and measurement function suited for precise current monitoring within the ranges of 3-30mA, 10-100mA, and 0.1-1A.
