Allen-Bradley 1492-CB1-G200 - 20A, 277VAC, Circuit Breaker

Engineered for industrial performance, the Allen-Bradley 1492-CB1-G200 is a 20A, 277VAC circuit breaker designed to provide reliable overcurrent protection where it matters most — in panelboards, switchboards, control panels, and OEM equipment.

Key specifications at a glance:

Current rating: 20A • Voltage rating: up to 277VAC • Breaker type: Circuit Breaker

These ratings translate into a robust protection solution for distributing power safely across equipment and machinery in demanding environments.

Why choose the 1492-CB1-G200 for your system:

• Dedicated 20A protection for circuits fed by up to 277VAC, making it suitable for commercial lighting feeds and industrial control circuits.
• Designed for use in panelboards, switchboards, control panels, and OEM equipment, ensuring compatibility with a wide range of industrial installations.
• Supports dependable overcurrent protection in distribution panels and motor control centers, helping prevent wiring damage and downstream equipment failures.

Practical use scenarios:

• Industrial automation panels where precise circuit protection maintains uptime for conveyors, presses, and automated tooling.
• OEM equipment requiring a trusted protection device to meet installation standards and simplify compliance checks.
• Commercial or light-industrial distribution where 277VAC circuits demand reliable branch protection without redesigning cabinet layouts.

What to expect in operation:

• Clear fault isolation: when an overload or fault occurs, the breaker interrupts the circuit to prevent further damage.
• Consistent performance across temperature and load variations common in industrial environments.
• Reliability rooted in a well-established brand legacy, helping reduce maintenance surprises in critical panels.

Tips for integration:

• Verify compatibility with your panelboard, switchboard, or MCC enclosure and confirm the form factor aligns with your backplane or bus system.
• Coordinate with your electrical design documents to ensure 20A protection aligns with the circuit's load calculations and wiring gauges.
• Follow best practices for safe installation, including proper termination torque and adherence to relevant electrical codes.
