Westinghouse | HCA2100X | Circuit Breaker | 2-Pole | 240V

Meet the Westinghouse HCA2100X, a purpose-built 2-pole circuit breaker designed for 240V protection across residential and light commercial panels. Built for maintenance, retrofit, and replacement projects where exact specifications matter, this breaker offers dependable performance when you need to restore or upgrade your electrical system with confidence.

Key specifications

• Pole configuration: 2-Pole
• Voltage rating: 240V
• Part number: HCA2100X

Why choose the Westinghouse HCA2100X

The HCA2100X represents a precise-fit solution for panels that require a matching 2-pole, 240V interruption device. The part number is the most reliable reference for compatibility, ensuring you don’t run into mismatches during a retrofit or replacement. This focus on exact specs helps streamline service calls, reduces downtime, and preserves the protection integrity of your electrical system.

Ideal for

Professionals performing panel maintenance or upgrades, homeowners replacing a failed or worn 2-pole 240V breaker in a Westinghouse-compatible load center, and electricians handling retrofit projects where maintaining original protection characteristics is critical. If your panel labeling calls for a 2-Pole 240V device with the HCA2100X specification, this breaker is a direct match.

What problems it solves

• Guarantees simultaneous disconnection of both hot legs on 240V circuits, enhancing safety for high-load appliances and equipment.
• Eliminates guesswork in compatibility by aligning with the exact part number, reducing ordering errors and installation delays.
• Supports reliable retrofits and replacements, helping you maintain code-compliant protection without altering panel characteristics.

How to verify compatibility

Before ordering, confirm that your panel accepts a 2-Pole 240V breaker and that the part number matches HCA2100X. Compare the panel’s labeling and the existing breaker footprint to ensure mounting style and fit align with the HCA2100X design. If in doubt, cross-reference the part number with your panel’s replacement guide to avoid incompatibilities.

Installation and safety tips

• Power down the main disconnect and verify absence of voltage before beginning any work.
• Follow manufacturer installation procedures and use appropriate PPE. Handle the breaker by its body and avoid contact with terminals while wiring remains connected.
• If you’re not comfortable performing electrical installation, consult a licensed electrician to ensure proper fit, connection, and safe operation.

Practical insights for better outcomes

When planning a retrofit or replacement, pairing the HCA2100X with compatible Westinghouse panels maintains consistent electrical protection characteristics across the system. Keep a record of the panel model and the HCA2100X part number for future maintenance or upgrades, reducing downtime and sequencing risk during service windows.
