1SVR550881R9400 ABB Control Industrial Automation Components

ABB 1SVR550881R9400 is a control relay designed for phase failure and neutral monitoring in both single-phase and 3-phase systems with fixed thresholds. It features 1 Normally Open (NO) auxiliary contact and is housed in an IP50 rated enclosure, with IP20 rated terminals. The control relay supports a communication protocol width of 78 mm, has a net height of 4 kV, and a rated impulse voltage (Uimp) of 22.5 mm. It is designed for a rated insulation voltage (Ui) of 78.5 mm and operates with a control voltage suitable for DIN rail mounting. The relay accommodates flexible and rigid wires in various AWG sizes for its Normally Closed (NC) auxiliary contacts. It operates at a wavelength of 50/60 Hz, supports supply voltages for 100,000 operations, and is capable of handling rated voltages (AC) for phase-to-phase at 240 V. The product is designed to be replaced by Silver Cadmium Oxide (AgCdO) components and has an analog output operational life of 30,000,000 operations. The net width is indicated by a yellow LED when the output relay is energized. It features screw-clamp trip units, operates within a temperature range of -20°C to +60°C, and has a control circuit rated current for various AC and DC applications. The relay's short circuit current breaking capacity (Icn) and protection settings are specified for both AC and DC currents, with a processing time and measurement function suited for operating rates at specified voltages.
