Q1-270 - 70 Amp Circuit Breaker

Q1-270 - 70 Amp Circuit Breaker

The Q1-270 70 Amp two-pole circuit breaker delivers dependable protection for electrical systems by combining precise thermal-magnetic trip performance with a compact footprint. Designed for maintenance and replacement applications, this breaker is suitable for residential and light commercial environments. Its plug-on design enables fast installation without sacrificing safety, making it an ideal choice when time and space are limited.

Key Features and Benefits

• High current capacity (70 A): Supports loads with headroom for surge and inrush currents while preventing nuisance trips.
• Thermal-magnetic protection: Dual mechanism ensures accurate response to both sustained overloads and sudden short circuits.
• Compact footprint: Occupies just four spaces in a panel, making it suitable for tight retrofit or retrofit installations.
• Plug-on mounting: Simplifies installation and reduces downtime during maintenance or replacement.
• Reliable performance: Consistent, predictable behavior under stress, giving installers and system owners confidence in protection.

Where It Works Best

• This breaker is a strong fit for maintenance and retrofit operations—serving to replace worn or failed breakers in existing panels where layout and space constraints exist. It is beneficial in commercial or industrial settings where 240 VAC loads require two-pole protection, but panel real estate is limited. In residential or light commercial installations, it can guard sub-circuits, HVAC units, pump motors, or other high-draw equipment safely and compactly.
