Manual Reset Control For Your DC Circuit
A practical circuit protection component designed for installations that require manual reset and convenient electrical disconnection.
This surface-mounted DC circuit breaker combines a reset lever and a separate manual-break button in a compact black housing. Its two-terminal design is intended for installation in compatible DC electrical circuits.
Choose from seven available amperage ratings, from 30A to 300A, to match the requirements of your specific installation.
Select the correct current rating before ordering. Each breaker has a fixed amperage rating.
Check Your Electrical Compatibility Before Ordering
The correct circuit breaker depends on more than the vehicle or equipment type.
Before selecting an amperage, confirm your system's DC voltage, required circuit-protection rating, wire and cable specifications, terminal connections, and available mounting space.
This product family is offered in seven fixed current ratings:
30A | 50A | 60A | 100A | 150A | 200A | 300A
Choose the rating specified for your electrical system. A higher amperage option is not automatically a better choice.
Important Compatibility Notes
- The supplier advertises a 12V–48V DC operating range, but the supplied manual specifically describes a 12V DC breaker. Confirm the correct DC voltage rating for the selected version before installation.
- Confirm that the breaker's required interrupting capacity is suitable for the available fault current.
- Verify terminal size, cable requirements, and mounting clearance.
- Use the component only where its electrical characteristics are appropriate for the installation.
- If the required rating is uncertain, consult a qualified automotive or marine electrical technician.
Who Is This Product For?
Customers installing or replacing a compatible DC circuit breaker where the required rating and connection details are known.
Who Is This Product Not For?
Customers looking for a universal breaker, a household AC circuit breaker, an automatically adjustable current rating, or a component with unverified safety certifications.
Manual Disconnect And Reset In One Unit
Two accessible controls make circuit interruption and reset straightforward.
The red push button provides manual disconnection, while the reset lever allows the breaker to be reset when conditions permit.
This design offers a reusable alternative to a conventional one-time fuse in applications where a correctly rated resettable circuit breaker is appropriate.
If the breaker trips unexpectedly, investigate and correct the electrical fault before resetting it.
Compact Construction For Surface-Mount Installation
The black housing features a compact mounting base, two electrical connection points, and protective terminal covers.
Its surface-mount configuration is designed for installations with appropriate mounting space and accessible wiring.
The product 100A reference drawing indicates an approximate overall size of 2.91 × 1.90 × 1.93 inches. Confirm these measurements against the version you are ordering and allow additional clearance for cables and terminal connections.
Designed For Compatible Automotive And Marine DC Applications
The product family is marketed for a range of low-voltage DC electrical installations, including automotive accessories, vehicle audio equipment, RV electrical systems, boats, and trolling motor installations.
Its manual-break and reset controls may be useful where a compatible circuit needs to be disconnected for maintenance or electrical management.
Suitability depends on the selected amperage, confirmed voltage rating, wiring, mounting arrangement, and applicable electrical requirements.
This breaker should not be assumed compatible with every vehicle, vessel, battery setup, or marine installation.
Choose The Correct Amperage
Seven amperage options are available, allowing customers to select the fixed current rating required for their installation.
Each option represents one circuit breaker with its own advertised nominal current rating.
The variants share the same general housing design in the supplier's reference materials. Their key documented difference is the rated current, not a verified difference in exterior dimensions, material, or mounting configuration.
30A - 30 amps
50A - 50 amps
60A - 60 amps
100A - 100 amps
150A - 150 amps
200A - 200 amps
300A - 300 amps
Variant notes:
- All seven versions are advertised with a manual reset mechanism.
- No confirmed variant-specific differences in housing color, physical dimensions, or included quantity were identified.
- The reference images predominantly show the 100A unit, so exact markings for the remaining versions require verification.
- Each amperage should be represented accurately on its respective variant image rather than using the 100A marking for every option.
Understand Installation Requirements
This breaker is intended for surface mounting within a compatible DC electrical circuit.
Installation requires proper electrical connection to the two terminals and secure mounting using appropriate hardware.
Before installation, disconnect and isolate the power source, verify the breaker rating, and check that the wiring, terminal connections, and mounting location are suitable.
Electrical installation may require appropriate tools, cable preparation, and professional assistance.
Do not reconnect power or reset a tripped breaker until any underlying electrical fault has been addressed.
For marine applications, verify that the component meets the specific environmental and ignition-protection requirements of the installation.
