Blue Sea 10A A2 Toggle Circuit Breaker, Milspec
Sealed Polymer Housing, Metal Faceplate & Threaded Panel Mount

DESCRIPTION
Heavy-Duty 10A Manual Switching and Overcurrent Protection
Engineered for demanding electrical environments, the Blue Sea 10A A2 Toggle Circuit Breaker combines reliable overcurrent protection with manual switching in a single, compact unit. Designed to safeguard critical wiring and electronics, this dual-purpose component eliminates the need for separate switches and fuse holders on your distribution panel. Its robust construction is tailored for marine, industrial, and specialized off-grid installations where mechanical durability and consistent electrical performance are paramount.
Rugged Construction for Demanding Environments
Unlike standard commercial-grade switches that can degrade under constant vibration or moisture exposure, this A2 series unit is built with high-grade materials to reduce the risk of premature mechanical failure. It features a durable silver metal toggle actuator and a heavy-duty metal front faceplate designed to withstand frequent manual operation. The internal mechanism is housed within a sealed polymer enclosure to protect against dust and environmental ingress, while a threaded mounting collar with a hex nut ensures a secure, vibration-resistant fit into your control panel.
Key Features and Benefits
- Dual-Function Design: Combines a manual ON/OFF toggle switch with precise 10A overcurrent circuit protection to save valuable panel space.
- Heavy-Duty Metal Hardware: Equipped with a solid metal toggle actuator and metal mounting faceplate for superior mechanical longevity in industrial and marine settings.
- Secure Panel Mounting: Features a threaded bushing collar and hex nut system that prevents loosening in high-vibration vehicle or vessel applications.
- Sealed Polymer Housing: Protects the internal trip mechanism from environmental contaminants, reducing the risk of corrosion and false tripping.
- Clear Technical Markings: Casing is clearly labelled with amperage, voltage, and delay characteristics for straightforward identification during installation and maintenance.
- CFR 46 Milspec Potential: Identified by the supplier as potentially suitable for applications requiring military specifications under CFR 46.
Regulatory and Application Context
This component is frequently selected by system builders and marine electricians working on commercial vessels, defence equipment, and heavy-duty mobile power setups. According to supplier documentation, this A2 Milspec model may be suitable for use when military specifications are required under Code of Federal Regulations (CFR) Title 46 for shipping and marine installations. Please note that this is a statement of potential suitability based on design parameters and does not constitute formal certification, approval, or compliance for a specific end-use application. Installers should always verify that the breaker's trip delay characteristics and voltage ratings align with their specific regulatory and circuit requirements.
