Product Description:

B & R Automation supplies the 8BVR0440H000.100-1 connector within its 8BVR Temperature Sensor Connectors series. This component serves as the power and signal interface between temperature sensors and a controller rack, allowing the sensors to be wired and isolated in an orderly way inside a control cabinet. In industrial automation, the unit links field temperature data to PLC- or PC-based control so process heat can be monitored, logged, and adjusted through closed-loop logic. It also helps keep cabinet wiring organized where several sensing points terminate near the control hardware.

The connector carries a continuous load of 45 A eff, allowing sustained current flow without conductor overheating. Its voltage rating of 480 V allows use with industrial single-phase or three-phase supplies that are common in heater and control circuits. An inductance value of 1 mH helps limit inrush transients and reduce switching spikes seen by upstream equipment. Thermal losses are limited by a power dissipation value of 330 W, so the enclosure must be able to remove heat during full-current operation. The housing has an IP20 protection rating and is intended for fixed installation inside equipment rather than exposed field mounting. Overvoltage Category III further indicates suitability for distribution-level circuits within industrial cabinets.

For short demand peaks, the assembly tolerates a surge of 90 A eff for less than ten seconds, providing added margin during startup or brief fault conditions. The metal frame must be installed in a horizontal standing position, and its 146 mm depth, 251 mm width, and 285 mm height help with backplate layout beside adjacent modules. Installed weight is 24.1 kg, so the mounting surface must support a relatively heavy component. In high-altitude plants, operation is allowed up to 4000 m, with the continuous current rating reduced by 3.6 A eff per 1000 m. Above 40 °C ambient, additional derating of 0.4 A eff / °C applies to limit thermal stress during operation.
