The 100 A rating makes it suitable for mid-range loads, providing protection without unnecessary tripping on normal operation.

This breaker is ideal for:

• Maintenance scenarios where you need a dependable, exact-spec replacement.
• Retrofit projects that must match existing panel layouts and trip characteristics.
• Replacement in panels that require a Westinghouse LA3100PR-compatible component to maintain system integrity.

Practical guidance for use

To ensure a trouble-free installation, verify that your panel’s labeling corresponds to 100A, 3-Pole, and 600V ratings and that the part number matches LA3100PR. This minimizes compatibility risk and helps preserve the panel’s protective coordination.

1. Power down the service and lock out all sources before handling equipment.
2. Cross-check the panel’s documentation or labeling to confirm LA3100PR compatibility.
3. Install the breaker according to manufacturer guidelines and local electrical codes.
4. Test the circuit under controlled conditions to verify proper operation and trip response.

Designed for professionals who value precision and dependable protection, the Westinghouse LA3100PR delivers peace of mind in everyday panel maintenance and in upgrades that require an exact spec match. If your project calls for a genuine 100A, 3-pole, 600V breaker with a clear reference point for compatibility, this is the model to choose.
