1SVR740760R0400 ABB Control Industrial Automation Components

ABB 1SVR740760R0400 is a current monitoring relay designed for single-phase current monitoring applications. It features a window current monitoring function, latching capability, and operates based on either an open circuit or closed circuit principle. This part includes an ON-delay/OFF-delay trip timer and utilizes DPDT (Double Pole Double Throw) contacts, offering 2 changeover contacts. The housing is rated at IP50 for protection, while the terminals are rated at IP20. It has a communication protocol width of 85.6 mm, a net height of 4 kV for rated impulse voltage (Uimp), and a protection function rating of 600 V for rated insulation voltage (Ui). The overall dimensions include a net height of 22.5 mm and a net width of 103.7 mm. It is designed for DIN rail mounting and supports control voltages in AC/DC from 24-240 V. The supply voltage is designed for 100,000 operations, with contacts made from a Silver-Nickel alloy (Ag/Ni) for enhanced durability, supporting up to 30,000,000 operations. It accommodates both flexible and rigid wires ranging from 0.5-1.5mm2 or 20-16AWG. The relay features a green LED for indicating control/supply voltage presence, a flashing green LED for timer activity, a red LED for overcurrent/undercurrent conditions, and a yellow LED when the output relay is energized. The tripping curve is adjustable from 0.1-30 seconds, with a spring-type trip unit and a minimum operating temperature of -20°C. The control circuit rated current is 4 A at 230Vac for AC-12 applications, 3 A at 230Vac for AC-15 applications, and 4 A at 24Vdc for DC-12 applications, with a short circuit current breaking capacity (Icn) of 2 A at 24Vdc for DC-13 applications. The maximum temperature for operation is +60°C, and it offers a measurement function with an operating rate for current settings of 3-30mA, 10-100mA, and 0.1-1A.
