Overview

20aAmperage

Guard an AC or DC electrical circuit against excess current with the Sea-Dog 20 Amp thermal circuit breaker. For boat electrical panels, it offers push-to-reset operation so a tripped breaker can be reset instead of replaced like a sacrificial fuse.

Key features

  • Thermal circuit protection helps prevent damage from excessive current.
  • Push-button resetting allows reuse after a trip.
  • Resistance to shock and vibration suits installations subject to movement.
  • A compact panel-mounted body keeps the breaker accessible at the panel.
  • Quick-connect terminals provide connection points with stamped brass contacts.
