1SVR740824R9300 ABB Control Industrial Automation Components

ABB 1SVR740824R9300 is a control relay designed for phase failure and sequence monitoring in 3-phase systems with fixed thresholds. It features DPDT (Double Pole Double Throw) contacts, offering 2 changeover contacts. The housing is rated at IP50, while the terminals are rated at IP20 for protection. This relay has a communication protocol width of 85.6 mm, a net height of 4 kV for rated impulse voltage (Uimp), and a width of 22.5 mm. It provides protection functions up to 600 V and a rated insulation voltage (Ui) of 103.7 mm. The control voltage is suitable for DIN rail mounting, and it supports both flexible and rigid wires ranging from 0.5-1.5mm2 or 18-16AWG to 20-16AWG for Normally Closed (NC) auxiliary contacts. It operates at a wavelength of 50/60 Hz, with a supply voltage indicating a durability of 100,000 operations. The number of NC circuits is rated at 500 V. This product, which uses a Silver-Nickel alloy (Ag / Ni) and is Cadmium-free (Cd-free), is designed for a high number of operations, up to 30,000,000. It features a red LED for phase failure or sequence error and a yellow LED to indicate when the output relay is energized. The trip unit type is spring, and it operates within a temperature range of -25°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 similarly rated for DC-12 and DC-13 at 24Vdc. The short circuit current breaking capacity (Icn) and protection settings are designed for robust operation, with a processing time and measurement function suited for operating rates of (L-L) 200-500Vac.
