Panasonic PM4HS-S-D provides precise star-to-delta transfer timing for AC motor starters. Independent dials set the star interval (0.2–100 s) and the transfer pause (0.04–0.7 s), enabling clean changeover with reduced current peaks. The unit features an 8-pin base and an IP50 front, making it ideal for compact MCCs and OEM panels.
