1SVR730824R9300 ABB Control Industrial Automation Components

ABB 1SVR730824R9300 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, and the terminals are rated at IP20 for protection. This relay has a control voltage requirement for DIN rail mounting and supports various wire sizes for Normally Closed (NC) auxiliary contacts, including flexible wires from 0.5-2.5mm2 to 18-14AWG and rigid wires from 0.5-4mm2 to 20-12AWG. It operates at a frequency of 50/60 Hz and has a rated insulation voltage (Ui) of 600 V, with a rated impulse voltage (Uimp) of 4 kV. The supply voltage leads to a rated operational life of 100,000 operations, while the analog outputs can handle up to 30,000,000 operations. The net width includes indicators: 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 a screw-clamp, designed for temperatures ranging from -25°C to +60°C. The control circuit rated current is 4 A for AC-12 and 3 A for AC-15 at 230Vac, and 4 A for DC-12 and 2 A for DC-13 at 24Vdc. The short circuit current breaking capacity (Icn) and protection settings are tailored for specific operational conditions, with an operating rate of 200-500Vac (L-L).
