Siemens HQR23B100HL - 100 A, 240 V, 3-Pole Bolt-On Circuit Breaker | AmpState

The Siemens HQR23B100HL delivers dependable branch circuit protection for panelboards and loadcenters, combining rugged construction with precise protection. At 100A and 240V across three poles, this bolt-on molded case circuit breaker is purpose-built for dependable, continuous operation in commercial, light industrial, and select residential applications where a solid, hard-wired protection solution is required. Key features that set this breaker apart - Bolt-on mounting for a secure, vibration-resistant bus connection: Designed to stay firmly seated in demanding environments, reducing the risk of loose connections and intermittent faults that can disrupt service. - Thermal-magnetic trip unit for stable, repeatable protection: The thermal element handles gradual overloads while the magnetic element responds instantly to short-circuit conditions, delivering fast isolation of faults and minimizing equipment damage. - OEM-compatible with Siemens loadcenters and panelboards: Engineered to fit seamlessly with matching Siemens equipment, helping you achieve clean, coordinated protection and straightforward maintenance. - Versatile for residential, commercial, and light industrial use: Whether powering a small business HVAC feed, a motorized circuit, or a multi-load distribution panel, this 3-pole breaker provides reliable distribution protection where you need it most. - Clear electrical parameters for confident selection: 100A rating at 240V and 3 poles, specifically configured for branch circuit overcurrent and short-circuit protection in consolidated electrical enclosures. Why engineers and installers choose the HQR23B100HL - Robust mechanical integrity: A bolt-on design creates a solid mechanical interface with the bus that resists vibration and contact creep, a common concern in busy service rooms and equipment closets. - Predictable fault response: The thermal-magnetic mechanism delivers consistent performance across varying temperatures and loads, helping maintain selectivity and reduce nuisance trips in mixed-use installations. - Tailored for Siemens ecosystems: When upgrading or expanding panelboards and loadcenters, staying within the same family ensures electrical coordination, simplified stocking, and easier warranty support. Practical use scenarios - Upgrading feeder protection in a three-phase commercial panel where a bolted connection is preferred for reliability. - Protecting motor feeds, HVAC controls, or lighting circuits in light industrial spaces that require solid, long-term bus connections. - Replacing aging breakers in Siemens HQR-series panelboards to restore full protection with a compatible, OEM-matched device. Maintenance and installation tips - Ensure mounting surfaces and bus connections are clean and free of debris before installation to maximize the benefits of the bolt-on design. - Verify compatibility with your Siemens panelboard or load center to maintain proper coordination and trip characteristics. - Schedule periodic inspections of the breaker during routine panel maintenance to confirm secure mounting and reliable operation. The Siemens HQR23B100HL is a purpose-built, high-integrity solution for protecting electrical distribution networks where rigid mounting, dependable trip performance, and OEM compatibility matter most. Install it where you need steadfast branch circuit protection with a 3-pole, 100A, 240V bolt-on configuration.
