Industrial RE1020B 20A 1-Pole 120 V Circuit Breaker

The Industrial RE1020B 20A 1-Pole 120 V Circuit Breaker is engineered for dependable, on-demand protection of critical electrical circuits in commercial and light-industrial environments. With a 20-amp current rating and a single-pole design, it cleanly interrupts power to a single circuit when overcurrent or a fault is detected, helping minimize damage and downtime.

Key specifications

• Current rating: 20 A
• Poles: 1
• Voltage rating: 120 V
• Part number: RE1020B

What makes the RE1020B unique

• Compact, space-conscious design: The 1-pole form factor fits neatly in standard industrial panels and control cabinets without crowding adjacent components.
• Direct, reliable protection for branch circuits: Specifically configured for 120 V systems, it provides prompt interruption to prevent equipment damage from overloads or faults.
• Simplicity and compatibility: Built to work with common wiring schemes and installation practices found in industrial settings, reducing setup time and confusion during panel upgrades or replacements.

Practical use cases

Ideal for protecting individual branch circuits that feed motors, lighting, sensors, and control circuitry in factories, warehouses, or workshops. If you’re updating an electrical panel, replacing a failed breaker, or standardizing protection across multiple feeders, the RE1020B offers a straightforward, dependable option for 120 V circuits.

Who benefits most

• Maintenance teams and electricians overseeing industrial panels and control enclosures.
• Facility managers seeking reliable, easy-to-source protective devices for everyday equipment loads.
• Contractors performing panel retrofits or new installations in light-industrial environments.

How it helps you avoid common pain points

By providing dedicated protection for a single 120 V circuit, this breaker helps prevent nuisance trips from minor surges and overloads while ensuring fast restoration once the fault is cleared. Its straightforward rating and form factor simplify inventory management and replacement decisions, so maintenance downtime is minimized.

Tips for installation and care

• Verify that the target circuit operates within the 120 V, 20 A range before installation.
• Ensure secure, clean connections to prevent loose-terminal issues that can lead to intermittent trips.
• Periodically inspect for signs of overheating or corrosion in the panel area and replace the unit if wear is detected or if performance declines.

Designed to deliver reliable branch-circuit protection in demanding environments, the RE1020B 20A 1-Pole 120 V Circuit Breaker is a focused, practical choice for safeguarding industrial electrical systems with clarity and confidence.
