LAL36350 - 350 Amp Circuit Breaker

LAL36350 - 350 Amp Circuit Breaker

The LAL36350 is a 350-amp, 3-pole Type LA molded-case circuit breaker designed for equipment that requires its specific ratings, mounting arrangement, and physical size. It uses a thermal-magnetic trip system that combines thermal overload sensing with magnetic short-circuit sensing in each pole. It also includes Push-to-Trip, which lets you manually trip the breaker without exposure to live parts. For replacement work, check more than the 350A rating. Properly selected, installed, and used within its specified ratings, the LAL36350 is built to last in the application it was designed for.

Key Features and Benefits

• 350A, 3-pole design for equipment requiring this Type LA configuration.
• Thermal-magnetic protection responds to overload and short-circuit conditions.
• Unit-mount configuration for compatible equipment.
• Line and load lugs provide the specified electrical connection arrangement.
• Uses AL400LA terminals.
• Push-to-Trip provides a straightforward way to trip the breaker without manual exposure to live parts.

Where It Works Best

The LAL36350 makes the most sense when maintaining or repairing equipment designed around a 350A, 3-pole Type LA circuit breaker with matching electrical and physical requirements.

Start with the electrical numbers: 350A, three poles, 22kA at 600VAC, or 10kA at 250VDC where the DC rating applies. Then check the installation itself. This breaker is unit-mounted, uses line and load lugs with AL400LA terminals, and has an approximate footprint of 11"H x 6" W x 5.84"D.
