Yaskawa Electric Z1B1B003PMG Variable Frequency Drive

The Yaskawa Electric Z1B1B003PMG is a 2 HP, 480 VAC, 3-phase bypass-enabled variable frequency drive from the Z1000 Bypass series designed for HVAC and industrial motor control. It provides precise speed regulation with a built-in bypass path so the system can continue to operate during maintenance or fault conditions, and is commonly used in air handling units, pumps, fans, compressors, and other industrial automation applications. Key specs include a rated current of 3.4–3.5 A, NEMA 1/IP20 enclosure, wall or panel mounting, and compatibility with Yaskawa Z1000 HVAC drive systems for building automation and energy-efficient HVAC setups. Common replacements include the GA800 drive, Z1B1B004PMG, and CIMR-ZU4A0004FAA.
