Blue Sea 30A A-Series Single Pole Toggle Circuit Breaker - Red

DESCRIPTION

Magnetic Hydraulic AC Main Circuit Protection and Switching

The Blue Sea A-Series Double Pole Circuit Breaker integrates reliable manual switching and overcurrent protection into a single, compact panel-mount device. Engineered specifically for demanding marine, RV, and off-grid electrical environments, this unit is typically deployed for AC main circuit protection. By utilizing a two-pole configuration, it simultaneously disconnects both the active (hot) and neutral lines, mitigating the risk of shock hazards caused by reverse polarity or elevated neutral voltages common in shore power and mobile inverter setups.

Why Choose Magnetic Hydraulic Technology?

Unlike standard thermal breakers that rely on heat-sensitive bimetallic strips, this Blue Sea Systems breaker utilizes an advanced magnetic hydraulic mechanism. Standard thermal units can suffer from nuisance tripping in hot engine bays or enclosed electrical cabinets, or fail to trip promptly in freezing conditions. A magnetic hydraulic circuit breaker senses only the actual current flowing through the circuit via a solenoid coil and fluid-damping dashpot. This ensures the trip curve and amperage rating remain stable and predictable regardless of ambient temperature fluctuations.

Key Features and Safety Benefits

  • Simultaneous Dual-Pole Disconnection: Isolates both circuit conductors at the same time through an internally linked mechanism, essential for safe AC main panel isolation.
  • Trip-Free Safety Mechanism: Engineered with an internal latch that cannot be manually held in the ON position during an active fault current condition, preventing catastrophic wire damage and fire risks.
  • Temperature-Stable Operation: Magnetic hydraulic actuation prevents nuisance tripping in high-temperature marine and automotive enclosures.
  • Dual-Function Design: Combines a durable manual toggle switch with precision overcurrent protection, reducing panel clutter and wiring complexity.
  • Secure Panel Mounting: Features integrated brass-threaded mounting holes for straightforward, vibration-resistant front panel installation.
  • Global Compliance Standards: Meets rigorous ABYC standards for marine safety, and is UL 1077 recognised, TUV certified, CE marked for Europe, and CSA certified for Canada.

Engineered for Harsh Marine and Mobile Environments

When designing a 240V AC distribution panel for a vessel, caravan, or specialized service vehicle, component reliability is critical. Lower-grade switches often lack true trip-free mechanisms or fail prematurely due to vibration and coastal humidity. The A-Series housing is built to withstand harsh operating conditions, featuring an ergonomic toggle actuator that provides clear visual and tactile indication of circuit status.

Whether you are upgrading an existing marine switchboard, installing an off-grid inverter distribution panel, or building a custom RV electrical system, this double-pole breaker reduces the risk of electrical fires and equipment damage. Upgrade your AC main distribution panel with the Blue Sea A-Series Double Pole Circuit Breaker for dependable, compliant circuit isolation.
