Parts Desk Insights

Best Use Case: Ideal for restoring protection and reset functionality on a DC accessory circuit when your existing Sierra push-button style breaker needs replacement and the panel cutout is a 3/8" hole.

Common Issues: Confirm the panel cutout size (3/8") before installation. Also match the breaker’s terminal style and consider whether you need the compatible weatherproof boot nut (MP39210) for your mounting location.
