1SVR740712R1400 ABB Control Industrial Automation Components

ABB 1SVR740712R1400 is a temperature controller with an analog interface, designed for thermistor motor protection. It features a thermistor motor protection relay, options for auto, manual, or remote reset, and dynamic interrupted wire detection. This part includes non-volatile fault storage, short-circuit detection, and a test button. It has 1 Normally Open (NO) auxiliary contact and offers protection with housing rated at IP50 and terminals at IP20. The communication protocol width is 85.6 mm, with a net height of 4 kV and a rated impulse voltage (Uimp) of 22.5 mm. The protection functions are rated at 300 V, with a rated insulation voltage (Ui) of 103.7 mm. It operates on a control voltage (AC) mounted on a DIN rail, with a response time facilitated by 1 NC contact. The auxiliary contacts accommodate both flexible and rigid wires, with sizes ranging from 2 x 0.5-1.5mm2 to 2 x 18-16AWG for flexible wires and 2 x 20-16AWG for rigid wires. The operating frequency range is 15-400 Hz, and it supports a supply voltage for AC/DC of 24-240 V. The device is designed for 100,000 operations, with the contacts made from a Silver-Nickel alloy (Ag / Ni) and are Cadmium-free (Cd-free). The analog outputs are designed for 30,000,000 operations. The net width is indicated by a green LED for control/supply voltage presence, a red LED for fault messages, and a yellow LED when the output relay is energized. The trip unit type is a spring, and it operates within a temperature range of -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 designed to meet specific operational requirements, with a processing time and measurement function tailored for precise control.
