Potter W93-X112-20 - 20A, 277VAC, 3-Pole, Circuit Breaker

Meet the Potter W93-X112-20, a purpose-built 20A circuit breaker engineered for 277VAC three-phase systems. With a robust 3-Pole configuration, this unit delivers coordinated protection across all three conductors in panelboards, switchboards, and control panels—ideal for industrial environments, commercial facilities, and OEM equipment where reliable, safe electrical protection is non-negotiable.

Key features that matter in real-world setups

• Current rating: 20A, providing precise protection for standard three-phase loads without nuisance trips.
• Voltage rating: 277VAC, aligning with common commercial and industrial distribution networks and lighting/control circuits.
• Poles: 3-Pole, ensuring simultaneous disconnection of all phases for safer fault isolation in three-phase installations.
• Breaker type: Circuit Breaker designed for dependable overcurrent protection in distribution panels and motor control centers.

Where it shines

The Potter W93-X112-20 is engineered for environments where three-phase power is the norm and panel reliability is mission-critical. Use it in:

• Panelboards and switchboards that feed commercial lighting, HVAC, and processing equipment.
• Motor control centers and other OEM assemblies that require fast, coordinated shutoff across all phases.
• Industrial facilities seeking durable, field-replaceable protection for critical electrical circuits.

Why this breaker can be a smarter choice

Unlike generic single-phase options, the W93-X112-20 is designed to match three-phase distribution needs at 277V, streamlining specification and stocking for projects that require consistent performance across all three poles. Its three-pole configuration minimizes arcing risk during fault conditions by ensuring all conductors trip together, reducing potential damage and downtime. For installation teams and OEM engineers, this means faster deployment, easier compliance with panel labeling, and a dependable safeguard for sensitive machinery and lighting systems.

Practical installation and compatibility tips

• Confirm your equipment and panelboard specifications match a 20A, 277VAC, 3-Pole breaker to ensure seamless integration.
• Verify the W93-X112-20 part number aligns with your existing Potter products if you’re replacing a similar unit or stocking for future maintenance.
• Plan for three-phase protection in environments where building automation and commercial power distribution rely on consistent, coordinated shutoff across all phases.
