BTA20.3-NA-WP-VB-BS

The Bosch Rexroth Indramat BTA20.3-NA-WP-VB-BS module is a durable and high-performance control unit in the BTA20 Machine Control Boards range, engineered by Bosch Rexroth Indramat for demanding industrial automation environments. The part_number BTA20.3-NA-WP-VB-BS incorporates a robust Toggle Actuator and provides a straightforward ON-OFF switch function, delivering reliable manual control over heavy currents. Its compact footprint and panel-mount design ensure seamless integration into existing control panels, while the Weatherproof protection rating guarantees operation in harsh or wet conditions. With a 20 A current rating and Silver Alloy contact material, this component balances high load capacity with long-term durability.

This control board’s technical architecture is defined by precise specifications: it features a Single Pole configuration, a Panel Mount mounting type, and a Standard BTA series panel cutout for compatibility with legacy installations. The unit is built to operate across an Operating Temperature Range of -20°C to +85°C and withstands environmental stresses thanks to its Weatherproof protection rating. Signal and power connections utilize a Wire Leads termination style, simplifying wiring processes during installation. Advanced communication is supported via the INTERBUS-S / BT-BUS communication bus, enabling seamless data exchange in complex automation networks. Additional identifiers include Product: BTA, Design: 3, and Configuration: NA-WP-VB, reflecting its modular build and series lineage.

In operation, the BTA20.3-NA-WP-VB-BS delivers consistent switching performance under cyclical loads, leveraging its 20 A current rating and Silver Alloy contact material to minimize contact wear and reduce maintenance intervals. The Toggle Actuator mechanism offers tactile feedback and clear on-off positions, enhancing operator ergonomics and minimizing switching errors. Its Single Pole configuration ensures isolated circuit control, while the Panel Mount mounting type secures the unit firmly against vibration and mechanical shock. The broad Operating Temperature Range extends usability from sub-freezing environments to elevated process temperatures, and the Weatherproof protection rating protects internal components from moisture ingress.

System designers can integrate this module directly into control cabinets, remote junction boxes, or outdoor enclosures without additional sealing, thanks to its Weatherproof protection rating and standardized Standard BTA series panel cutout. Compatibility with the INTERBUS-S / BT-BUS communication bus enables straightforward network integration, supporting real-time diagnostics and centralized monitoring. Ideal applications include industrial machine control, outdoor pump stations, conveyor systems, and factory automation panels where reliable, high-current switching and environmental resilience are essential. The Bosch Rexroth Indramat BTA20.3-NA-WP-VB-BS offers a proven solution for end-users seeking robust performance, straightforward installation, and seamless integration into sophisticated automation architectures.
