Mastervolt 70905140 – 40A Red Double Circuit Breaker Rocker
The Mastervolt 70905140 is a high-amperage double-pole thermal circuit breaker rated at 40A, designed to provide full isolation of both poles in AC and DC systems. Ideal for 230V installations or isolated 12/24V DC applications, it ensures secure disconnection of both phase and neutral—or positive and negative—lines during overload or short circuit events. The red rocker actuator provides intuitive manual control and reset functionality.
Engineered for marine, RV, and industrial applications, the breaker offers a compact snap-in design, high interrupt capacity, and full compliance with CE, UL 1077, CSA, and ABYC E-11 electrical safety standards.
