1SVR550824R9100 ABB Control Industrial Automation Components

ABB 1SVR550824R9100 is a control relay designed for phase failure and sequence monitoring in 3-phase systems with fixed thresholds. It features a Single Pole Double Throw (SPDT) contact type, offering 1 Changeover (C/O) contact. The housing is rated IP50, and the terminals are rated IP20 for protection. This relay is compatible with a DIN rail mounting system and supports a control voltage (AC) for operation. It accommodates flexible and rigid wires ranging from 0.75 to 1.5mm2 or 18-16AWG for connections. The relay operates at a wavelength of 50/60 Hz, with a supply voltage for AC circuits at 440 V and a rated insulation voltage (Ui) of 600 V. It has a rated impulse voltage (Uimp) of 4 kV and a net height of 78.5 mm. The relay's control circuit is rated for currents up to 4 A at 230Vac for AC-12 applications, 3 A at 230Vac for AC-15 applications, and similarly rated for DC-12 and DC-13 applications at 24Vdc. It features a yellow LED indicator for relay energization status and utilizes screw-clamp terminals for secure connections. The operating temperature range is from -20°C to +60°C, ensuring functionality across a wide range of environmental conditions.
