LAL3640022M - 400 Amp Motor Circuit Protector

LAL3640022M - 400 Amp Motor Circuit Protector

The LAL3640022M is a 400-amp, 3-pole Type LA motor circuit protector for equipment that requires this particular combination of ratings, mounting, connections, and physical size. If you're replacing an existing motor circuit protector, don't stop at the 400A rating. Check the poles, voltage, interrupting ratings, mounting arrangement, terminals, and dimensions against the equipment already in place.

Key Features and Benefits

• 400A, 3-pole configuration for equipment requiring these exact electrical characteristics
• Thermal-magnetic trip technology
• Unit-mount configuration for compatible installations
• Line and load lugs for the specified connection arrangement
• Uses AL400LA terminals
• A practical choice for maintaining compatible existing and legacy electrical equipment where matching form, fit, and function is important

Material Compliance and Certifications

The supplied specifications identify the LAL3640022M as UL Listed and CSA- and IEC-certified. These certifications can matter when matching a motor circuit protector to existing equipment or an application with defined compliance requirements.

Where It Works Best

The LAL3640022M makes the most sense in existing or legacy equipment that specifically calls for a 400A, 3-pole Type LA motor circuit protector with unit mounting and line/load lug connections.

For replacement work, put the old device's specifications next to this one and work through them. Start with 400A and three poles. Then confirm the required 22kA rating at 600VAC or 10kA at 250VDC, depending on the application. Next, check the unit-mount arrangement and AL400LA terminals. Finally, make sure the available space matches the 11" H x 6" W x 5.84" D footprint.
