• Poles: 2-Pole — suitable for two-pole installations common in industrial and commercial power distribution.
• Voltage rating: 600V — appropriate for medium-voltage panel boards and equipment within this range.
• Mounting style: Bolt-On — offers a secure, mechanically robust attachment to compatible panels, aiding long-term reliability in busy electrical rooms.
• Part number: HLB2400 — using the exact part number is the most reliable reference for compatibility.

Why this breaker stands out

The HLB2400 isn’t a generic substitute. It’s purpose-built to align with bolt-on panel configurations while delivering consistent performance in demanding applications. Its 400A rating makes it well-suited for feeder protection in mid to large electrical loads, and the 2-pole design ensures coordinated protection across connected circuits. By opting for a bolt-on construction, you gain a straightforward installation path with a solid mechanical connection that minimizes contact problems and reduces the likelihood of nuisance trips caused by loose fittings. When your project calls for a precise, durable replacement, the HLB2400 provides the exact specification alignment you need.

Ideal use cases

• Retrofits and replacements in panels that require bolt-on, 2-pole, 600V circuit breakers.
• Maintenance projects where a known, exact part number (HLB2400) is essential for compatibility.
• Industrial or commercial power distribution suppressing overloads on critical feeders up to 400A.
• Panel upgrades or upgrades to meet revised protection requirements without changing overall electrical architecture.

Installation and compatibility guidance

To ensure flawless performance, verify compatibility using the part number HLB2400 as your primary reference. Confirm that your panel accepts bolt-on breakers with a 2-pole, 600V configuration and that the amperage and terminal arrangement match your circuit’s protection needs. Given the specificity of bolt-on designs, this model is best suited for panels designed to accommodate Westinghouse bolt-on breakers and similar mounting schemes.

Practical considerations and tips

• Plan replacements around identical electrical characteristics—matching amperage, number of poles, and voltage rating ensures seamless integration.
• When performing retrofits, keep a record of the part number (HLB2400) for future service and ordering accuracy.
• Prior to installation, inspect the mounting area for clean terminals and proper bus alignment to maximize contact reliability.

Choose the Westinghouse HLB2400 when you need a proven 400A, 2-pole, 600V bolt-on circuit breaker with a precise part-number reference for compatibility. It’s built to protect your electrical system with clarity, reliability, and a retrofit-friendly footprint.
