Newmar 25 Amp Single Pole Breaker W/ Black Throw Product Description
Reliable Protection for Your Electrical Systems
When it comes to safeguarding sensitive electronics in demanding environments like boats, RVs, or off-grid setups, choosing the right circuit breaker makes all the difference. The Newmar 25 Amp Single Pole Breaker with Black Throw (model 25ASB) stands out for its robust construction and precise performance, delivering peace of mind against overloads and short circuits without compromising on safety or convenience.
Key Features That Set It Apart
- Magnetic-Hydraulic Trip-Free Mechanism: This advanced design ensures the breaker trips reliably under fault conditions and cannot be held in the "on" position once tripped, enhancing safety during high-current surges common in marine or mobile applications.
- Versatile Ratings: Rated at 25 amps for up to 65 VDC or 277 VAC, making it ideal for a wide range of AC and DC systems. Note that higher-amp models like 40-50A are limited to lower voltages for specific setups—always verify your system's requirements.
- Secure Wiring: Equipped with #10 screw terminals on the rear for straightforward, vibration-resistant connections that hold up in rough seas or bumpy roads.
- Universal Fit: Designed to slot seamlessly into Newmar electrical panels and compatible with most other brands, simplifying replacements or upgrades without panel modifications.
- Customizable Aesthetics: Black throw handle provides a sleek, professional look, with options for red or white if matching your panel's theme.
Why This Breaker Excels in Real-World Use
Boat owners and RV enthusiasts know the frustration of unreliable breakers that nuisance-trip or fail to protect. This single-pole model shines by combining UL recognition, CSA listing, and USCG approval into one compact package—meeting stringent standards for marine-grade reliability. Its trip-free operation means it resets easily after clearing the fault, minimizing downtime during adventures.
Beyond specs, think about longevity: the hydraulic delay curve prevents tripping from brief inrush currents, like when starting motors or inverters, keeping your inverters, pumps, and navigation gear running smoothly. Pair it with proper wire sizing (e.g., 10-12 AWG for 25A loads) to maximize efficiency and safety.
Installation Insights for Optimal Performance
Getting it right starts with preparation. Source mounting screws separately (typically #8-32) to secure it firmly in your panel. Disconnect power sources before wiring—connect the line to the terminal marked "LINE" and load to "LOAD" for single-pole setups. Torque to spec (around 25 in-lbs) to avoid loose connections that could spark issues over time.
Pro tip: In humid marine environments, apply dielectric grease to terminals post-installation to fend off corrosion, extending the breaker's service life significantly.
Understanding Ratings for Safe Application
A quick note on ratings: While perfect for standard 115/230V split-phase systems (common in North American marine/RV setups), higher-amp variants aren't suited for direct 230 VAC line-to-neutral. Stick to the 25A sweet spot for most DC-heavy applications under 65V, ensuring compliance and protection.
Frequently Asked Questions
What type of trip mechanism does the Newmar 25 Amp Single Pole Breaker use?
It features a magnetic-hydraulic trip-free mechanism, which provides precise protection by instantly responding to short circuits via magnetic action and delaying for overloads hydraulically. This prevents accidental overrides for superior safety.
Is this breaker compatible with panels from other brands?
Yes, it fits all Newmar electrical panels and most other brands with standard mounting dimensions, making it a versatile replacement option without needing panel alterations.
What certifications does this circuit breaker hold?
It's UL recognized and CSA listed for both AC and DC systems, plus it satisfies USCG requirements as a qualified protection device—ideal for marine and recreational vehicle compliance.
What are the voltage and amp ratings for the 25ASB model?
Rated for 25 amps at up to 65 VDC or 277 VAC, suitable for most marine, RV, and solar setups. Always cross-check with your system's voltage profile.
Does it come with mounting hardware?
Mounting screws are not included and should be ordered separately. Standard #8-32 screws work best for secure installation in panels.
What handle color options are available?
Options include red, white, or black toggle handles. The black throw version offers a clean, modern appearance that blends well with many panel designs.
How does single-pole differ from double-pole breakers?
Single-pole protects one circuit leg (e.g., 120V or DC positive), while double-pole handles both legs simultaneously (e.g., 240V). Choose based on your load—25A single-pole suits most branch circuits.
All circuit breakers offered by NEWMAR are UL recognized and CSA listed for AC and DC
systems and meet USCG requirements as a qualified circuit protection device.
