Commander15/40/40/15 amp Quad Circuit Breaker BQLT-15-240 - 40 A, 240 V Bolt-On Circuit Breaker | AmpState

Meet the Commander BQLT-15-240 Quad Circuit Breaker — a 40A, 240V bolt-on molded‑case breaker designed for dependable branch circuit protection in panelboards and load centers. Built to endure the demands of residential, commercial, and light industrial installations, this four‑pole device delivers reliable overcurrent and short‑circuit protection where it matters most.

Why this breaker stands out

• Secure bolt‑on mounting: A rigid, vibration‑resistant bus connection minimizes movement and wear, helping your panel stay solid under heavy use or busy electrical rooms.
• Thermal‑magnetic trip unit: Combines precise overload protection with fast short‑circuit clearing for predictable, repeatable protection performance across varying loads and temperatures.
• Quad/pole design for 240V systems: The 4‑pole configuration provides coordinated protection for multi‑wire circuits and 3‑phase or high‑demand panels, reducing nuisance trips and simplifying panel layouts.
• OEM‑compatible: Specifically designed to pair with matching OEM load centers and panelboards, ensuring a seamless retrofit or new installation with consistent electrical characteristics.
• Versatile for diverse environments: From home subpanels to light commercial setups, this breaker delivers the reliability needed in everyday electrical infrastructure.
