Siemens BQD6220 - 20 A, 600 V, 2-Pole Bolt-On Circuit Breaker | AmpState

Siemens BQD6220 is a rugged, two-pole molded-case circuit breaker designed to deliver dependable branch-circuit protection in panelboards and load centers. With a 20-amp rating and a 600-volt maximum, this bolt-on unit provides a secure, vibration-resistant connection that stays put in demanding electrical environments. What sets the BQD6220 apart - Bolt-on mounting for a rigid, low-movement bus connection that helps prevent loose contacts and arcing in spaces with vibration or movement. - Thermal-magnetic trip unit combines precise thermal overload protection with fast magnetic tripping for short-circuit events, delivering stable, repeatable protection performance. - Designed for direct compatibility with matching OEM Siemens load centers and panelboards, ensuring a clean fit, reliable operation, and streamlined replacement. - Versatile across residential, commercial, and light industrial applications, making it a practical choice for service panels, subpanels, and upgrade projects. Why this matters for you - Clear protection when you need it most: the thermal element guards against nuisance trips from minor overloads, while the magnetic trip reacts decisively to dangerous short circuits, helping to minimize downtime and damage. - Peace of mind from a trusted brand: Siemens engineering means proven performance, predictable trip characteristics, and alignment with other Siemens distribution components. - Long-term reliability in challenging environments: the bolt-on design provides a secure mechanical connection that resists loosening over time, reducing maintenance needs in busy electrical rooms or noisy equipment spaces. Ideal use cases - Replacing a failed or aging breaker in a Siemens panelboard or load center without sacrificing compatibility. - Subpanel installations in light commercial settings where a robust, 2-pole protection device is required for shared neutrals or multi-wire branch circuits. - Residential upgrade projects that demand a dependable, code-compliant 20A circuit breaker for outlets, lighting, or dedicated equipment. - Industrial-light environments where a durable, 600V-rated breaker can safely protect motor controllers and distributed loads.
