What Is a Feed-Thru Circuit Breaker?

A feed-thru (or feed-through) circuit breaker allows conductors to pass through the breaker terminals, enabling downstream connections without the need for additional lugs or bus connections. This makes the FAL36050 ideal for panelboards and distribution systems where wiring flexibility and space savings are required.

Thermal Magnetic Trip Technology

The FAL36050 uses thermal magnetic trip technology — the industry standard for molded case breakers. It provides two levels of protection:

• Thermal (Long-Time) Trip: Protects against sustained overloads by responding to heat buildup over time.
• Magnetic (Instantaneous) Trip: Responds immediately to high-current short-circuit faults, minimizing damage to equipment and wiring.

Common Applications

• Commercial and industrial panelboards
• Three-phase power distribution systems
• Motor branch circuit protection
• HVAC, lighting, and equipment feeder circuits
• Manufacturing facilities and plant electrical systems

Why Choose the Square D FAL36050?

Square D is one of the most trusted names in electrical distribution. The FAL series is UL-listed and widely specified by engineers and electrical contractors for its consistent performance, availability of replacement parts, and compatibility with Square D panelboards and switchgear. The FAL36050 is a direct fit for applications requiring a compact, 3-pole, 50A breaker with feed-thru termination capability.
