Square D FA36100 - 100A 3 Pole Molded Case Circuit Breaker.

The Square D FA36100 functions as a 100-Ampere, 3-pole molded case circuit breaker (MCCB) engineered for robust electrical distribution and branch circuit protection. This F-Frame breaker provides essential overcurrent and short-circuit shielding for three-phase electrical systems in demanding environments. The unit-mount design allows for seamless integration into various electrical assemblies, ensuring circuit integrity and equipment safety.

Industrial-Grade Overcurrent Protection

The FA36100 utilizes a sophisticated thermal-magnetic trip mechanism to provide dual-layered protection. The thermal element responds to long-term overloads by monitoring heat buildup, while the magnetic component provides instantaneous protection against high-level short circuits. This combination ensures maximum uptime by preventing nuisance tripping while maintaining a rapid response to critical electrical faults.

Technical Specifications and Performance

This Square D F-Frame breaker is built to withstand the rigors of heavy-duty applications. Key performance attributes include:

• Amperage Rating: 100A continuous current capacity for medium-to-heavy electrical loads.
• Voltage Compatibility: Supports systems up to 600VAC, making it suitable for a wide range of industrial power configurations.
• Pole Configuration: 3-pole design facilitates the protection of three-phase power circuits.
• Interrupting Rating: Provides high-level AIC (Ampere Interrupting Capacity) to safely clear faults within the electrical system.
• Mounting Style: Unit-mount configuration allows for direct installation using lugs on both the line and load sides.

Versatile Application and Use Cases

The FA36100 is a versatile component found in numerous power distribution settings. It is frequently utilized in:

• Commercial Panelboards: Protecting branch circuits in office buildings, retail spaces, and warehouses.
• Industrial Switchboards: Managing power distribution for machinery and heavy equipment.
• Motor Control Centers (MCCs): Serving as a reliable disconnect and overcurrent protector for motor circuits.
• Infrastructure Projects: Ensuring stable power delivery in healthcare facilities, educational institutions, and data centers.

Durable Construction and Build Quality

Square D constructs the FA36100 with high-quality molded materials that offer excellent dielectric strength and mechanical durability. The compact frame size optimizes space within electrical enclosures without compromising performance. The internal contacts are designed for high conductivity and minimal resistance, reducing heat generation during peak operation. The clear toggle handle provides immediate visual indication of the breaker status (On, Off, or Tripped), simplifying maintenance and troubleshooting procedures.

Installation and Compatibility

The FA36100 features standard mechanical lugs that accept copper or aluminum conductors, providing flexibility during the wiring process. The unit-mount design ensures compatibility with various Square D enclosures and mounting hardware. Proper installation ensures a secure electrical connection and prevents localized heating at the termination points.
