1SVR740660R0100 ABB Control Industrial Automation Components

ABB 1SVR740660R0100 is an insulation monitor designed with a single threshold insulation monitoring relay function, rated for a DC voltage of 300 V. It features SPDT (Single Pole Double Throw) contacts, with a protection rating of IP20. The device has a communication protocol width of 85.6 mm, a net height of 6 kV, a rated impulse voltage (Uimp) of 22.5 mm, and a rated insulation voltage (Ui) of 103.7 mm. It is suitable for DIN rail mounting and supports a control voltage (AC) with consumption values of 0.9 VA at 24Vdc, 2 VA at 115Vac, and 3.2 VA at 230Vac. The unit includes Normally Closed (NC) auxiliary contacts compatible with both flexible and rigid wires of sizes 0.5-1.5mm2 or 20-16AWG. It operates within a frequency range of 15-400 Hz and can handle supply voltages of AC/DC 24-240 V, with a life expectancy of 100,000 operations for the number of circuits and 30,000,000 operations for analog outputs. The frame current rating varies with voltage, showing 0.035 A at 24Vdc, 0.017 A at 115Vac, and 0.014 A at 230Vac. Indicators include a green LED for control/supply voltage presence, a red LED for fault messages, and a yellow LED for output relay energization. The trip unit type is a spring, and it operates within a temperature range of -25°C to +60°C. The earthing system compatibility includes IT (AC), IT (DC), and IT (AC/DC mixed), with control circuit rated currents of 4 A at 230Vac for AC-12, 3 A at 230Vac for AC-15, 4 A at 24Vdc for DC-12, and 2 A at 24Vdc for DC-13. The device's short circuit current breaking capacity (Icn) and protection settings are designed for robust operation, with a processing time and measurement function tailored for precise insulation monitoring. The operating rate is specified for 1-100kΩ, and it supports cable categories of 250Vac and 300Vdc for (L-PE). The storage type is specified for system leakage at 10 µ, indicating a focus on maintaining insulation integrity.
