Specifically engineered for demanding electrical environments, this heavy-duty breaker is built to manage substantial electrical loads, making it an essential component for high-draw appliances such as power inverters, marine bow thrusters, and anchor windlasses.\u003c\/p\u003e\n\u003cp\u003eBy integrating both switching and protection functions, this C-Series unit simplifies electrical panel layouts and eliminates the need for separate battery switches and fuse blocks. Whether you are outfitting a commercial marine vessel, upgrading a caravan 12V or 24V power system, or building a custom off-grid electrical enclosure, this circuit breaker provides reliable circuit management where safety and space efficiency are paramount.\u003c\/p\u003e\n\n\u003ch3\u003eFlush-Mount Actuator for Enhanced Operational Safety\u003c\/h3\u003e\n\u003cp\u003eIn mobile and marine applications, accidental switching can lead to unexpected power loss to critical systems or unintended activation of heavy machinery. The C-Series flat rocker is specifically contoured to sit completely flush with the mounting bezel when in the ON position. This low-profile geometry significantly reduces the risk of accidental operation caused by bumps, snagged clothing, or shifting gear in tight quarters.\u003c\/p\u003e\n\u003cp\u003eFor immediate visual confirmation of your system status, the recessed actuator reveals a high-visibility coloured indicator when switched to the OFF or tripped position. This intuitive design allows operators to identify the state of the circuit at a glance, even in dimly lit helm stations or crowded battery compartments.\u003c\/p\u003e\n\n\u003ch3\u003eUncompromising Trip-Free Protection and Heavy-Duty Terminations\u003c\/h3\u003e\n\u003cp\u003eSafety during an electrical fault is critical to preventing wire damage and electrical fires. This Blue Sea breaker incorporates an internal trip-free mechanism, which ensures the internal contacts cannot be manually held closed during an overcurrent or short-circuit event. If a fault persists on the line, the breaker will trip internally regardless of physical pressure applied to the external rocker actuator, protecting your cabling and connected equipment until the fault is resolved.\u003c\/p\u003e\n\u003cp\u003eUnlike standard residential or light-duty automotive switches that struggle with heat dissipation under heavy loads, the C-Series is constructed for high-current continuity. The rear of the unit features heavy-duty 5\/16\" (approx. M8 or 7.9mm) terminal studs designed to accommodate large-gauge ring terminals and busbars securely. These substantial studs provide maximum surface contact for low-resistance connections, while integrated brass threaded inserts on the front casing ensure secure, vibration-resistant panel mounting.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features and Benefits\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual-Function Design:\u003c\/strong\u003e Combines manual on-off circuit switching with reliable 100A overcurrent protection in one compact footprint.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlush ON Rocker Profile:\u003c\/strong\u003e Sits flat when engaged to prevent accidental switching in high-traffic or mobile environments.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClear Visual Status:\u003c\/strong\u003e Coloured actuator surface clearly indicates the OFF position for rapid system checks.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip-Free Safety Mechanism:\u003c\/strong\u003e Internal contacts cannot be forced or held closed during an active overcurrent fault condition.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeavy-Duty Terminal Studs:\u003c\/strong\u003e Equipped with 5\/16\" (approx.
