Blue Sea Push Button Reset Only Screw Terminal Circuit Breaker - 40 Amps

The Blue Sea Push Button Reset Only Screw Terminal Circuit Breaker – 40 Amps (MPN 2137) is a compact, reliable branch circuit protection device engineered for marine electrical systems aboard fishing vessels, cruising boats, and offshore platforms. This 40-amp push-button reset circuit breaker provides dependable overcurrent protection in high-density panel configurations where space and reliability are equally critical.

The push-to-reset operation delivers straightforward manual control—trip the breaker under fault conditions, inspect the electrical circuit, and reset by pressing the button to restore power. The screw terminal connection style integrates seamlessly into Blue Sea Systems WeatherDeck Waterproof Circuit Breaker Panels, Dual Battery Bank Main Distribution Panels, and 360 Distribution Panels, as well as custom marine electrical builds requiring modular circuit protection. The compact design enables high-density circuit configurations without sacrificing accessibility, critical aboard vessels where panel space is at a premium. At 40 amps, this breaker handles branch circuits serving navigation systems, cabin lighting, refrigeration, and auxiliary engine loads typical on medium to large recreational and commercial vessels.

This breaker suits weekend anglers upgrading cabin systems and professional offshore operators managing complex electrical architecture. Whether protecting a new galley circuit or replacing a failed breaker in an existing WeatherDeck panel, the 40-amp rating and proven Blue Sea Systems engineering deliver the protection marine environments demand. Salt air, vibration, and load cycling expose circuit protection to continuous stress—this breaker's screw terminal connection resists corrosion and loosening common in marine duty.

For 24-hour continuous protection applications and branch circuit duty, the push-button reset mechanism provides intuitive fault response without panel modifications. Boaters and marine electricians trust Blue Sea Systems breakers as a foundational component of modern marine electrical systems.
