Rockford Fosgate RFCB200 200 Amp Circuit Breaker
Rockford Fosgate RFCB200 200 Amp Circuit Breaker
When a blown fuse at the wrong moment means a full rewire job, the RFCB200 replaces a standard fuse holder with a 200-amp manual-reset circuit breaker that gets your system back online without touching the wiring.
Product Overview
The RFCB200 is Rockford Fosgate's 200 Amp Circuit Breaker, designed to protect high-power car audio amplifier systems from overcurrent events without the cost and downtime of replacing a blown fuse. Rated at 200 amps, it covers the protection requirements of high-output monoblock and multi-amplifier installations running 1/0 AWG or 4 AWG main power cable. All terminals are platinum plated for superior corrosion resistance and low-resistance electrical contact, and use a set-screw style connection that accepts bare wire directly without requiring ring terminals, simplifying installation and future servicing. When an overcurrent event occurs, the RFCB200 trips rather than blowing, and can be manually reset once the fault has been identified and cleared. The low-resistance, high-current design ensures minimal voltage drop across the breaker during normal operation, preserving maximum available voltage at the amplifiers. 1-year warranty.
Features & Benefits
Manual Reset Circuit Breaker: Unlike a fuse that must be replaced after an overcurrent event, the RFCB200 trips and can be manually reset once the fault condition has been resolved. This eliminates the need to carry spare fuses and allows the system to be restored to operation quickly in the field.
200 Amp Rating: Rated at 200 amps continuous, the RFCB200 provides the overcurrent protection threshold required by high-power amplifier systems, including monoblock subwoofer amplifiers such as the R2-1200X1 and multi-amplifier builds where combined fuse requirements reach or exceed this rating.
Platinum Plated Terminals: All connection terminals are platinum plated for superior corrosion resistance and low-resistance electrical contact, maintaining a clean, reliable connection over the life of the installation without the oxidation issues common to standard plated terminals.
Set-Screw Style Connection: The set-screw terminal design accepts bare wire directly without requiring ring terminals or crimped lugs, reducing the number of connection points in the power run and simplifying both initial installation and future servicing.
Multiple Wire Gauge Compatibility: Accepts 1/0 AWG and 4 AWG power cable, covering the wiring gauge requirements of the majority of high-power car audio amplifier installations without requiring adaptor fittings.
Low-Resistance, High-Current Design: Internal resistance is minimised to ensure negligible voltage drop across the breaker during normal operation, preserving the full supply voltage available from the battery and alternator for the amplifiers downstream.

The RFCB200 is a direct replacement for the main power fuse or fuse holder in high-power car audio installations. It is best suited to systems running high-output monoblock amplifiers such as the R2-1200X1, which specifies a 200A recommended fuse, or multi-amplifier builds where combined fuse requirements approach this rating. It sits in the main power cable run between the battery and the amplifier distribution point, installed as close to the battery as possible. A 1/0 AWG amplifier wiring kit is recommended for power and ground runs at this current rating. For systems also using the RFC10HB capacitor, the RFCB200 is installed in the power cable between the battery and the capacitor.
Frequently Asked Questions
What is the advantage of a circuit breaker over a standard blade or ANL fuse in a car audio system?
A standard fuse is a one-time protection device that must be physically replaced after an overcurrent event, which can mean carrying spare fuses and a delay in restoring the system if a fault occurs away from home. A manual-reset circuit breaker like the RFCB200 trips when an overcurrent event occurs and can be reset by hand once the fault has been identified and cleared, restoring the system to operation without replacing any components.
Does the RFCB200 require ring terminals for installation?
No. The set-screw terminal design on the RFCB200 accepts bare wire directly, tightened into the terminal with the set screw. This removes the need for ring terminals or crimped lugs at the breaker connection points, reducing the number of potential resistance points in the power run and making installation and future servicing more straightforward.
Where should the RFCB200 be installed in the power cable run?
The RFCB200 should be installed in the positive power cable as close to the battery terminal as possible, within 30-45 cm of the battery in most installations. This placement ensures that the maximum length of power cable between the battery and the amplifiers is protected against overcurrent and short-circuit events. The negative or ground cable does not pass through the circuit breaker.
What amplifiers does the 200 amp rating suit?
The 200 amp rating covers the protection requirement for Rockford Fosgate's R2-1200X1 monoblock amplifier, which specifies a 200A recommended fuse, making the RFCB200 a direct match for that amplifier's power protection needs. It also covers multi-amplifier builds where the combined fuse ratings of several amplifiers add up to this threshold. For lower-power systems specifying 60A or 50A fuses, the RFCB100 or RFCB140 are the appropriate options.
Can the RFCB200 be used as a main disconnect switch as well as a circuit breaker?
The RFCB200 is a circuit breaker with manual reset capability, not a purpose-designed disconnect switch. While manually tripping the breaker will interrupt the power supply to the amplifiers, it is not rated or designed as a deliberate on/off switch and repeated manual operation outside of fault conditions may affect the breaker's calibrated trip threshold over time. A dedicated battery disconnect switch is recommended if a regular power isolation point is needed in the installation.
