Zinsco UBIZ0240 - 40A, 2-Pole, Circuit Breaker

Zinsco UBIZ0240 is a dependable 40A, 2-pole circuit breaker engineered for robust overcurrent protection in distribution systems. Its two-pole design ensures that both conductors are interrupted together on a fault, promoting safer shutdown and reducing the risk of line-to-line faults in the event of an electrical surge.

• Current rating: 40A
• Poles: 2-Pole
• Breaker type: Circuit Breaker

Ideal for industrial, commercial, and OEM environments, the UBIZ0240 shines in panelboards, switchboards, and control panels where reliable protection and safe operation are non-negotiable. Whether you’re upgrading aging equipment, expanding a warehouse distribution setup, or designing a new motor control center, this 40A two-pole breaker delivers consistent performance where it matters most.

Why choose the Zinsco UBIZ0240 for your electrical protection needs?

• With a dedicated 40A rating, it guards branch circuits and equipment from overloads and short circuits without over-restricting normal operation.
• Two-pole reliability: Simultaneous interruption of both hot conductors helps prevent dangerous arcing and protects connected motors and devices during faults.
• Versatile application fit: Designed for panelboards, switchboards, and control panels, it adapts to a range of industrial and commercial distribution setups.
• OEM-friendly and scalable: Suitable for OEM builds and modular installations where consistent protection standards are required across multiple panels.

Practical use scenarios include: upgrading a panel for a new 40A circuit serving a critical piece of machinery, equipping a motor control center with reliable feeder protection, or integrating into a distribution panel in a manufacturing line where rapid, safe disconnection is essential. For best results, verify compatibility with your enclosure, ensure proper alignment with existing bus connections, and follow standard installation practices to maintain safe and effective operation.
