FAL34100 | Schneider Electric Circuit Breaker

The FAL34100 is a 3-pole, 100-ampere molded case circuit breaker (MCCB) manufactured by Square D. It is part of the FAL series and specifically designed for Heating, Air Conditioning, and Refrigeration (HACR) applications. The breaker is rated for use in 3-phase systems with a maximum voltage of 480 VAC. 

Key Features: 

Overcurrent Protection: The FAL34100 provides protection against overcurrent conditions in 3-phase electrical systems. It achieves this through a dual-function trip unit with both long-time and instantaneous trip characteristics. The long-time element offers overload protection for sustained overcurrents, while the instantaneous element provides short-circuit protection for sudden current surges. 

Standard Interrupting Capacity: The breaker has a standard interrupting capacity of 18kA at 480 VAC. This value represents the maximum symmetrical fault current the breaker can interrupt without failure. 

Thermal Magnetic Trip Unit: The FAL34100 utilizes a thermal magnetic trip mechanism for comprehensive overcurrent protection. The thermal element responds to sustained overloads based on heating effects, while the magnetic element reacts rapidly to short-circuit currents. The "LI" designation likely indicates a specific time-current curve for the long-time element, but the datasheet should be consulted for details. 

Line and Load Side Lug Terminals: The breaker features line and load side lug terminals for secure connection of cables. These terminals are designed to accept cables of appropriate gauge and comply with relevant installation standards. 

Unit Mount Configuration: The FAL34100 is designed for unit mount installation. This means it can be directly mounted onto a mounting plate or busbar within an electrical panel.
