FAQs
To install the PDB321-1, align the block with your panel mounting area and secure it to the panel as a panel-mount device. Connect conductors to the tin-plated aluminum connectors, ensuring proper conductor sizing for up to 175 A. Verify IP-20 finger-safe access is maintained and route wiring to minimize stress on terminations. After installation, perform a continuity check and inspect for secure fasteners and clean electrical contacts to ensure reliable operation.
The PDB321-1 is rated for 175 A, with a voltage rating of 600 Vac / 600 Vdc and a short-circuit rating (SCCR) of 200 kAIC. It features IP-20 finger-safe protection and a single-pole configuration using tin-plated aluminum connectors. These specifications provide robust high-current distribution capability while maintaining safety and compatibility with both AC and DC control circuits in industrial panels.
