Why it matters

Protection matters when it comes to reliability and safety. The thermal-magnetic trip unit provides a precise response to overcurrents and short circuits, helping to prevent damage to wiring and connected equipment while keeping nuisance trips to a minimum. The 2-pole design ensures both legs disconnect together, which is essential for safe operation in typical 120/240V circuits found in many residential and light commercial applications. With OEM compatibility, you can trust this breaker to align with your panel’s original specifications and performance expectations.

Ideal uses and scenarios

• Upgrading or replacing a 100A feeder or branch circuit in residential panels and subpanels.
• Installing in light commercial or small industrial panels that require reliable, code-compliant overcurrent protection.
• Stocking a dependable spare for preventive maintenance in service panels and load centers.
• Retrofitting legacy panels where OEM compatibility ensures proper fit and function.

Compatibility and installation notes

• Designed to be compatible with matching OEM General Electrics load centers and panelboards for straightforward retrofits and replacements.
• Choose the correct amperage and pole configuration to match the protected circuit and panel design.
• Ensure proper handling and secure mounting within the approved panel enclosure following standard electrical practices.
