Thermal Circuit Breaker 10 Amp by Sea Dog Marine (420810-1)


Boaters need to give importance to safety measures while sailing. Electricity in a boat is crucial, especially when you are in contact with water. Never compromise one’s life, choose only the best quality. That is what Recmar is known for in the marine industry. Recmar is committed to manufacturing products that -pass thorough testing before it is well packed to be delivered.

THERMAL CIRCUIT BREAKER 10 AMP (3-420810-1) is a circuit protection device that consists of molded bakelite construction with easy connection, terminal style, and stamped brass connections. During an overcurrent, heat is generated when the current passes through the reed, forcing it to deflect and snap open.

THERMAL CIRCUIT BREAKER 10 AMP (3-420810-1) carefully isolates the contacts and interrupts the current flow. After tripping, it has a resettable advantage, as opposed to sacrificial fuses. It keeps both you and your watercraft away from any electrical damage, from possibly life and death situations.

Key Features:

  • Cost-Effective.
  • Shock and Vibration resistant.
  • Transport the load current without overheating.
  • Designed to survive even in a harsh marine environment.
  • Current overload prevention for engine motors and transformers.
  • Made from durable materials that last years of service.
