Square D FA36070 - 70A, 3-Pole, Circuit Breaker

Meet the Square D FA36070 — a rugged 70 A, 3-Pole circuit breaker designed to deliver dependable overcurrent protection in demanding environments. Built for industrial, commercial, and OEM applications, this unit is a reliable backbone for distribution panels and motor control centers where safe, continuous operation matters.

• Current rating: 70 A
• Poles: 3-Pole
• Breaker type: Circuit Breaker
• Ideal mounting points: Panelboards, Switchboards, and Control Panels

Why a 3-Pole design matters: this unit provides simultaneous disconnection of all three phases in three-phase systems, improving safety and simplifying maintenance in complex electrical layouts. It’s purpose-built to stand up to the rigors of real-world use in distribution and motor control applications.

Key use cases

• Three-phase panelboards in manufacturing lines, processing facilities, and commercial complexes
• Switchboards in process automation and plant distribution schemes
• Motor control centers requiring reliable phase protection for rotating equipment
• OEM equipment where a compact, single-unit 3-Pole protection device streamlines installation

What makes the FA36070 stand out is its focused design for consistent performance in demanding conditions. It consolidates three-phase protection into one rugged unit, reducing wiring complexity and panel footprint while maintaining robust safety margins for overcurrent events. This translates to fewer nuisance trips, clearer diagnostics, and faster service when inspection or replacement is needed.

Whether you’re upgrading an aging panel, building a new distribution system, or outfitting an OEM application, the Square D FA36070 delivers precise, reliable protection for three-phase circuits. Pair it with compatible enclosures and wiring practices to ensure optimal performance and long service life in your electrical infrastructure.
