HARTING Han Protect 3A Connector
The HARTING Han Protect 3A Connector is an innovative solution designed to integrate overcurrent and short-circuit protection directly into a size 3A connector. By incorporating a 5x20mm fuse, this connector eliminates the need for bulky fused terminal blocks and offers an efficient alternative to circuit breakers. The compact design reduces cabinet size, streamlines installation, and lowers total cost of ownership (TCO). Ideal for applications requiring reliable circuit protection, the Han Protect 3A Connector combines functionality, space-saving design, and cost-efficiency in a single, versatile component.
- Space savings of up to 30% by eliminating extensive fuse terminal rows inside of the control cabinet
- Reduce the deployment time with Plug & Play solution which adapts the established M12 A-Coded interface
- Enable troubleshooting for lower qualified workers on Extra Low Voltage (ELV) at closed cabinets
- Increased system availability due to simplified troubleshooting on broken fuses
