Q221225AB - 225 Amp Circuit Breaker

Protect your electrical systems with confidence using the Q221225AB molded-case circuit breaker. Designed for high-demand environments, this dual-pole breaker offers dependable overcurrent protection across residential, commercial, and industrial installations. With its plug-on I-Line mounting system and rugged Q-Frame housing, the Q221225AB delivers a streamlined installation experience and enduring performance. Its built-in thermal-magnetic trip mechanism responds quickly to overloads or short circuits, offering a 10 kA interrupting capacity at 120/240 VAC to guard your system and equipment.

Key Features and Benefits

• Thermal-Magnetic Trip Mechanism: Blends thermal overload protection (for sustained overcurrent) with magnetic short-circuit response for fast action when a fault occurs.
• Plug-On I-Line Design: No extra hardware or adapters needed; slides directly into standard I-Line bus bars for fast, clean installation.
• Q-Frame Construction: A sturdy molded housing built to resist damage and ensure stability in demanding environments.
• Dual-Pole with A-B Phasing: Ideal for protecting 240V circuits by balancing loads across both poles, with precise phase alignment.
• High Interrupting Rating: Rated for 10,000 A interrupting capacity at 120/240VAC, giving you reliable fault-clearing power.
• Space-Efficient Dimensions: Measuring 3.00″ W × 7.88″ L × 4.31″ D, it fits neatly in many standard panels without excessive bulk.
