LAL3640028M - 400 Amp Motor Circuit Protector

LAL3640028M - 400 Amp Motor Circuit Protector

The LAL3640028M is a 400-amp, 3-pole Type LAL circuit breaker with Mag-Guard™ magnetic-only, instantaneous-trip operation. It also uses a cable-in/cable-out configuration. If you're replacing an existing breaker, check more than the 400A rating. The pole count, AIC, voltage, magnetic-only trip design, adjustment range, connections, and physical size must all match the equipment. When properly selected, installed, and used within its specified ratings, the LAL3640028M is built to last in the application it was designed to serve.

Key Features and Benefits

Material Compliance and Certifications

The supplied specifications for the LAL3640028 M did not include any specific UL, CSA, IEC, RoHS, REACH, or other certification or material-compliance information. Because those details weren't provided, don't assume them.

Where It Works Best

The LAL3640028M makes the most sense when you're working with existing or legacy electrical equipment that calls for a 400A, 3-pole Type LAL breaker with magnetic-only, instantaneous-trip operation.

Put the important numbers side by side with the breaker you're replacing. Does the application require 22kA at 600VAC, 30kA at 480VAC, or 42kA at 240VAC? Does it call for the 750–1600A adjustable trip range? Check those items first.
