Maxwell P100791 135 Amp Circuit Breaker Windlass Isolator 12/24V

The Maxwell P100791 is a heavy-duty 135-amp circuit breaker and isolator designed specifically for marine windlass systems. This dual-voltage unit works with both 12V and 24V DC systems, providing essential overcurrent protection and battery isolation for Maxwell 800 through 3500 Series 12V windlasses and 4000 Series 24V windlasses.

Key Features:

• 135-amp rating suitable for high-draw windlass applications
• Compatible with 12V and 24V DC electrical systems
• Protects main conductor circuit for DC windlasses and control circuit for hydraulic windlasses
• Provides short circuit protection to prevent DC motor burnout during overload conditions
• Allows complete electrical isolation when windlass is not in use, preventing parasitic battery drain
• Panel-mount design for easy installation near battery source
• Factory-compatible with Maxwell 800, 1000, 1200, 1500, 2200, 2500, 3500 Series (12V) and 4000 Series (24V) windlasses

This breaker/isolator should be mounted as close as possible to the battery or power source to maximize circuit protection and ensure proper operation. The isolator function is particularly useful for preventing battery discharge during extended periods when the windlass is not in use, making it an essential safety component for any vessel equipped with an electric windlass system.
