8BVR0880H000.100-2 by B & R Automation

B & R Automation manufactures the 8BVR0880H000.100-2 connector as part of its 8BVR Temperature Sensor Connectors series. This device serves as a high-current interface for temperature-sensing modules, routing power and signal lines inside industrial control cabinets. By combining mechanical fastening with defined current paths, the unit allows sensor assemblies to be disconnected for service without rewiring and keeps wiring density manageable. It is typically mounted on backplanes or DIN rails where multiple thermocouple or RTD channels converge. This arrangement helps keep cabinet wiring organized when several sensing circuits terminate in the same enclosure.

The connector's busbars are designed for a continuous load of 90 Aeff. For short demands under ten seconds, the permissible surge climbs to 180 Aeff. When the installation altitude exceeds 1000 m, capacity falls by 7.2 Aeff/1000 m, so current planning must be adjusted for high-elevation sites. Internal conductors dissipate 420 W at the nominal current, which should be considered when arranging cabinet airflow. The housing carries an IP20 touch-safe rating and is assigned Overvoltage Category III, so it is suitable for distribution circuits fed directly from facility mains. The protected housing also helps reduce accidental contact with energized parts inside the cabinet.

The connector measures 412 mm high, 293 mm wide, and 165 mm deep, so the enclosure must allow enough clearance for mounting and cable routing. At 40.2 kg, the assembly requires rigid support brackets to prevent strain on connected cabling during vibration. It operates in ambient temperatures up to 55 °C and tolerates storage or transit conditions to 70 °C without material degradation. The physical size and weight make stable mounting important where dense cabinet layouts or moving equipment can transfer mechanical stress to the connection points.
