LX36400G - 400 Amp Circuit Breaker

LX36400G - 400 Amp Circuit Breaker

The LX36400G is a 400 amp, 3-pole LX molded-case circuit breaker with a plug-in configuration, featuring MicroLogic™ thermal-magnetic protection and a current-limiting design. If you are selecting a breaker for an existing or older electrical system, the details matter.

Key Features and Benefits

• The 400A rating refers to the current rating specified for electrical equipment that requires this amperage.
• The three-pole configuration suits applications that require a three-pole breaker setup.
• The specified plug-in arrangement is important when checking whether it fits the existing equipment.
• The current-limited breaker is a current-limiting molded-case circuit breaker.
• MicroLogic™ Thermal-Magnetic: Uses the chosen MicroLogic™ thermal-magnetic setup.
• Adjustable Long-Time Settings: Lets you set the long-time ampere rating and delay.
• The short-time settings are adjustable, including the short-time ampere rating and delay.
• The instantaneous pickup setting can be adjusted as specified for this breaker.
• The ground-fault pickup and delay are adjustable.
