Parts Desk Insights
Best Use Case: Use for DC/AC branch or load circuit switching and protection where a trip-free magnetic-hydraulic breaker is required, and where you want the breaker to serve as both the switch and protective device.
Common Issues: Most common install issues are choosing the wrong breaker rating (amperage/voltage) and incorrect terminal hardware. Verify you have the correct ring terminals, matching terminal screw hardware, and proper mounting panel cutout/alignment for the breaker you’re replacing.
