- Selection & Replacement Notes
- Voltage matching: AB = 1phase 200V; A2/A4 = 3phase 200V/400V. Do not mismatch.
- Power matching: Last 3 digits (e.g., 015 = 1.5 kW). Keep power consistent when replacing.
- Interface compatibility: 3G3JZ has builtin RS485 (Modbus). Confirm port and protocol.
- Terminals & dimensions: Prefer samesize models to minimize wiring and modification.
