Selection Guide
Choosing a Circuit Breaker
Reset & Operation
- Manual-reset DC breakers restore the circuit after the fault is cleared.
- Switchable versions also provide a manual disconnect; operating functions vary by model.
- Equipment push-to-reset types are not necessarily ON-OFF switches.
Voltage & Current
- Match the breaker to the DC system voltage and required current rating.
- Available ratings and interrupting capacity differ between versions.
- For equipment breakers, use the separate AC or DC rating and required trip characteristic.
Mounting & Connection
- Cable-clamp versions require the correct wire size and connector fit.
- Stud-terminal versions require matching cable lugs and confirmed thread dimensions.
- Match the mounting format, installation clearance and documented exposure conditions.
Equipment options: Compact thermal push-button and rocker breakers, plus hydraulic-magnetic toggle types, serve different panel requirements. These equipment versions require their own circuit ratings and panel-fit specifications.
Applications
Typical Circuit Breaker Applications
Choose the protection function for the load and installation.
Automotive Accessories & Car Audio
DC breakers for amplifier supplies, auxiliary wiring and vehicle accessory power. Match current, voltage and cable connections to the circuit.
Marine & RV Power Wiring
Manual-reset options for onboard accessory and auxiliary power circuits. Specify the exact electrical ratings and installation exposure requirements.
Equipment & Control Panels
Thermal push-button and rocker types, plus hydraulic-magnetic toggle breakers, support separate equipment-panel requirements.

For a Project Enquiry
Use the checklist below to prepare your breaker requirements.
Send Project DetailsNo. The listed automotive DC range includes manual-reset breakers, with switchable versions that also allow manual disconnection. Reset and operating controls differ by model. Clear the cause of the trip before resetting; do not assume an equipment push-to-reset button is an ON-OFF switch.
No. DC voltage limits, current options and interrupting capacity depend on the exact version. Match these specifications to the circuit and request the confirmed datasheet. An AC rating cannot be used as evidence of the same DC capability.
No. The generator interlock kits listed here are separate mechanical accessories that prevent simultaneous breaker operation. They do not provide overcurrent protection. For these kits, use the product-specific panel compatibility and installation drawing.
No. Protection depends on the exact breaker, covers, terminals and complete installation. Use documented exposure and sealing requirements for the chosen version. A waterproof cover description or a rating on one product does not apply to the whole range.
Compact thermal push-button breakers provide overload protection, while rocker versions combine protection and switching. Hydraulic-magnetic toggle versions include different pole arrangements. Select these by the equipment circuit ratings, trip requirements and panel fit. Thermal cutoffs and thermostats are separate temperature-protection parts.
