LAL3640022M - 400 Amp Motor Circuit Protector

LAL3640022M - 400 Amp Motor Circuit Protector

Delivering top-tier protection for industrial motor systems, the Schneider Electric LAL3640022M motor circuit protector is engineered to safeguard your electrical assets while enabling dependable performance in demanding settings. With a nominal current rating of 400 A in a 3-pole configuration, this device is designed to prevent motor damage by precisely interrupting overloads and short circuits. Its thermal-magnetic trip unit balances sensitivity to gradual overcurrent with rapid response to faults, giving your system proactive defense. Designed for versatility, the unit supports operation at up to 600 VAC or 250 VDC, making it a wise choice for high-demand environments. Rugged enough for daily use yet refined in function, the LAL3640022M is ideal where uptime, safety, and efficiency matter most.

Key Features and Benefits
