Quick WCB 40A DC Magnetic Hydraulic Circuit Breaker
(Manufacturer Code: FDWCB0400000A00)
The hydraulic magnetic circuit breaker Quick WCB 40A is an amperometric protection device specifically designed for marine systems in direct current (DC). Thanks to its “slow burn” intervention curve (delayed action), it can tolerate the physiological initial inrush peaks typical of marine electric motors, interrupting the circuit precisely only in case of real overload or prolonged short circuit.
Fields of Application
Ideal for the outfitting, upgrading, or maintenance of electrical panels and onboard circuits. It is the preferred technical component for:
-
Protection of power supply lines for anchor windlass, winches, capstans, and bow thrusters.
-
Safe management of marine electrical panels operating at voltages below 80 Vdc.
-
Direct and guaranteed replacement (OEM) of pre-existing components bearing the same manufacturer code.
Validated Technical Specifications
-
Rated Current (Trip): 40 Amperes
-
Max Operating Voltage: 80 Vdc (Direct Current)
-
Operating Temperature: from -40°C to +85°C
-
Reset Mechanism: Manual via dedicated lever
-
Panel Aesthetics: Scratch-resistant glossy surface with minimal frame
Dimensional Data for Recessed Installation
-
Front Plate Dimensions: 74.8 mm (Height) x 49.8 mm (Width)
-
Total Depth (Recessed): 67 mm
-
Circuit Breaker Projection: 30.4 mm
Installation and Safety Guidelines
To ensure the effectiveness of protection and the safety of the onboard system, installation must comply with the component's nameplate parameters:
-
Wiring Method: The device must be wired strictly in series on the positive pole (+) cable.
-
Sizing: Use power cables with an adequate cross-section (calculated based on the length of the nautical run) to support continuous loads of 40A. It is essential to use well-crimped ring terminals to ensure a secure tightening on the rear poles, avoiding overheating.
-
Safety Intervention: Every assembly or replacement operation must be carried out with the system completely powered off (battery switch open). The back of the component (terminal block area) must be kept protected from direct water infiltration.
Compatibility Check: Before purchasing, make sure that the code FDWCB0400000A00 exactly matches the one on the component to be replaced or in the system manual provided by the shipyard. This ensures a quick and safe installation.
