Square D FA36030 - 30A 3 Pole Molded Case Circuit Breaker

The Square D FA36030 serves as a robust 30-amp, 3-pole molded case circuit breaker engineered to safeguard electrical circuits from overcurrent and short-circuit conditions. This F-frame unit provides essential power distribution control and equipment protection within complex commercial and industrial electrical infrastructures. It functions as a critical safety component by automatically interrupting electrical flow during fault conditions to prevent hardware damage and fire hazards.

Technical Performance and Trip Characteristics

The FA36030 operates with a 30A continuous current rating and supports a maximum voltage of 600VAC. The three-pole configuration allows for the simultaneous protection and switching of three-phase electrical systems. This breaker utilizes a thermal-magnetic trip mechanism to provide a dual layer of protection: a bi-metallic element handles long-time overcurrent protection for persistent overloads, while an electromagnetic solenoid provides instantaneous response to high-level short circuits.

Industrial-Grade Construction and Durability

Square D constructs the FA36030 with a high-strength molded case that provides superior dielectric properties and mechanical protection for internal components. The FA36030 circuit breaker features high-quality terminal lugs designed to maintain secure, low-resistance electrical connections even under varying thermal loads. This durable construction minimizes maintenance requirements and extends the operational lifespan of the power distribution equipment in demanding environments.

Key Features and Benefits

• 30-Amp Current Rating: Provides precise overcurrent protection for branch circuits and small industrial loads.
• Three-Pole Design: Ensures comprehensive protection for three-phase power systems.
