QBL22200LU - 200 Amp Circuit Breaker

QBL22200LU - 200 Amp Circuit Breaker

When you need dependable, high-capacity circuit protection, the QBL22200LU delivers. This 200 Amp, 2‑pole thermal‑magnetic circuit breaker is built on the trusted QBL frame — offering solid, long-term performance in demanding electrical systems. With lug terminals on both the line and load sides and a 10 kAIC rating at 120/240 VAC, this breaker offers the strength and flexibility to safely handle heavy loads. Whether you’re wiring a commercial panel, upgrading an industrial load center, or protecting a critical sub‑circuit, the QBL22200LU makes sure your system stays protected under pressure.

Key Features and Benefits

• High‑Current Capacity: Rated for 200 Amps, this breaker supports substantial loads, making it ideal for main panels or sub‑panels for large equipment or multiple circuits.
• Dual‑Pole Protection: With 2 poles, the breaker provides comprehensive two‑line protection and 240 V circuit handling — perfect for heavy-duty circuits or systems requiring balanced supply.
• Thermal‑Magnetic Trip Unit: The integrated thermal‑magnetic mechanism combines overload protection with fast trip response in short‑circuit conditions, keeping wiring and connected devices safe from damage.
• Line and Load Lug Terminals: Lug connections on both line and load sides streamline installation and allow for clean, secure wiring terminals. This versatility simplifies set-up in retrofit or new‑build scenarios.
• Solid 10 kAIC Rating: With a 10 kA interrupting rating at 120/240 VAC, it's engineered to safely interrupt fault currents up to 10,000 Amps — ensuring reliable protection under high‑fault conditions.
