1SVR760487R8300 ABB Control Industrial Automation Components

ABB 1SVR760487R8300 is a multifunctional monitoring relay designed for 3-phase applications. It features phase failure detection, phase sequence monitoring, automatic phase sequence correction, and ON-delay / OFF-delay trip timer functionalities. This control relay has DPDT (Double Pole Double Throw) contacts, which are configurable as 2 x 1C/O or 1 x 2C/O. The housing is rated IP50, and the terminals are rated IP20 for protection. It supports a control voltage of 480Vac with a power consumption of 41 VA. The relay is designed for DIN rail mounting and has a net height of 103.7 mm. It offers overvoltage, undervoltage, and phase unbalance detection with a rated insulation voltage (Ui) of 1000 V and a rated impulse voltage (Uimp) of 4 kV. The supply voltage ranges from 350-580Vac at 50/60 Hz. The relay is capable of 100 000 mechanical operations and 30 000 000 electrical operations. It features silver-nickel alloy contacts that are cadmium-free. The frame current rating is 0.029 A at 480Vac, with a tripping curve of 0.1-30 s. The minimum operating temperature is -25°C, and the maximum is +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) is specified for various control circuit ratings. Terminal connections accommodate flexible wires of 2 x 0.5-1.5mm2 or rigid wires of 2 x 0.5-1.5mm2, and also flexible wires of 2 x 20-16AWG or rigid wires of 2 x 20-16AWG.
