Stinger SGP90200 200AMP Circuit Breaker

Stinger SGP90200 200 Amp Resettable Circuit Breaker for 0 Gauge and 4 Gauge Car Audio and Automotive Power Installations

The SGP90200 from Stinger is a 200 amp resettable circuit breaker from the SGP90 series, accepting 0 gauge (70mm²) or 4 gauge (25mm²) cable. Designed for high-powered car audio amplifier protection and general automotive accessory applications, it provides easy reset and disconnect capability without requiring fuse replacement after a trip event.

Product overview

The SGP90 series circuit breakers are designed for applications where the ability to easily set, reset, or defeat the circuit is preferred over a one-use fuse. The 200 amp rating suits extreme high-powered car audio amplifier installations and high-current accessory applications where the 150 amp SGP901501 does not provide sufficient headroom. In a typical audio application, transient music loads can swing significantly above and below the amplifier's rated full load current, and the SGP90200 is designed to allow these transient peaks to pass during normal operation while tripping on sustained fault conditions that indicate a genuine system problem.

The SGP90 series has predictable trip characteristics that can be forecast based on amperage load, duty cycle, and ambient temperature. For constant load applications such as inverters and other sustained high-current devices, the breaker capacity will decline in relation to the time and size of the load, and this should be considered during system design. The easy reset and disconnect function allows the breaker to be manually tripped for safe system isolation during installation or servicing.

Features and benefits

200 amp rating for extreme high-powered car audio and accessory installations: The 200 amp rating suits the most demanding car audio amplifier circuits and high-current accessory applications where a 150 amp breaker does not provide sufficient capacity for the expected transient load swings.

Easy reset and disconnect: Resettable design eliminates the need for fuse replacement after a trip event. The circuit can also be manually tripped for safe system isolation during installation or servicing.

Accepts 0 gauge and 4 gauge cable: Compatible with 0 gauge (70mm²) and 4 gauge (25mm²) cable, covering the most common large gauge cable sizes used in high-powered car audio and accessory power installations.

Predictable trip characteristics: The SGP90 series provides predictable trip behaviour based on amperage load, duty cycle, and ambient temperature, allowing the breaker to be selected and applied with confidence for specific installation requirements.

Suited to car audio and constant load accessory applications: Designed for car audio amplifier circuit protection as well as general automotive accessory applications where resettable circuit protection is preferred. For constant load applications, the load capability decline over time should be considered during system design.

Frequently asked questions

What is the difference between the SGP90200 and the SGP901501?
Both are SGP90 series resettable circuit breakers accepting 0 gauge and 4 gauge cable with identical design and predictable trip characteristics. The SGP901501 is rated at 150 amps and suits high-powered car audio amplifier installations. The SGP90200 is rated at 200 amps and suits extreme high-powered installations or high-current accessory applications where greater capacity is required. Select the rating that matches the expected full load current of your system with appropriate headroom for transient peaks.

What is the advantage of a circuit breaker over a fuse for car audio installations?
A circuit breaker can be reset after a trip event without requiring fuse replacement, making it more practical for installations where occasional overload conditions may occur. It can also be manually tripped for safe system isolation during installation or servicing, which a fuse does not allow.

How does the SGP90200 handle the transient load swings in a car audio system?
Music-driven amplifier loads swing significantly between minimum and maximum current draw during normal operation. The SGP90 series is designed to allow these transient peaks to pass while tripping on sustained fault conditions that indicate a genuine system problem. Contact us for guidance on selecting the correct breaker rating for your specific amplifier system.

Can the SGP90200 be used for constant load applications such as inverters?
The SGP90 series can be used for constant load applications, however the breaker capacity declines in relation to the time and size of the sustained load. This should be factored into system design for inverters and other constant high-current devices. Contact us for guidance on selecting the correct breaker rating for your specific constant load application.

What cable gauges does the SGP90200 accept?
The SGP90200 accepts 0 gauge (70mm²) and 4 gauge (25mm²) cable, covering the most common large gauge cable sizes used in high-powered car audio and accessory power installations.
