QDF32225TS - 225 Amp Circuit Breaker

QDF32225TS - 225 Amp Circuit Breaker

Protect your electrical system with confidence using the QDF32225TS circuit breaker—a high-capacity, dependable overcurrent device engineered for 240 VAC systems. This 3-pole breaker offers a 25 kA interrupting rating, making it well suited for demanding residential, commercial, or industrial environments where reliable protection and switching are critical. The thermal-magnetic trip mechanism responds precisely to overloads and short circuits, helping to safeguard wiring, equipment, and downstream loads. With its busbar mounting design, push-to-trip button, and heavy-duty cycling capability, this breaker is made to integrate into modern distribution systems and stand up to repeated use.

Key Features and Benefits

• High Interrupting Rating (25 kA): Delivers fault-clearing capability at both 208Y/120 VAC and 240 VAC, ensuring safety even under high-stress conditions.
• Thermal-Magnetic Trip Protection: Combines thermal (overload) and magnetic (short-circuit) response for accuracy and fast action.
• User-Friendly Operation: Includes an integrated push-to-trip button for testing and manual operation without the need for external tools.
• Busbar-Compatible Design: Uses stud-type connections on both line and load ends for streamlined integration with busbar systems.
• Long Life Cycle: Rated for 1,000 loaded cycles and 5,000 no-load cycles, delivering dependable performance over years of use.
