A circuit breaker that doesn't function correctly is a big concern for aviators. Electrical overload isn't a laughing matter, which is why SkyGeek keeps an ample supply of well-made aircraft circuit breakers guaranteed not to break your bank account. Count on affordability in the form of circuit breaker accessories as well: lockout rings and button caps are all a few dollars a piece.
The circuit breakers we carry are some of the lightest, best-performing options around. Designed to protect state-of-the-art aviation power systems, these devices are mandatory when it comes to preserving the integrity of your electrical equipment.
Endurance and reliability are always necessary and such circuit breakers fit the bill. Featuring high vibration resistance and boasting a high interruption capacity, these products can be counted on when traveling in an often hostile atmosphere. You wouldn't have second-rate circuit breakers in your house, would you? Nobody would want cheap, unreliable breakers in anything they own and maintain, and that goes double for aircraft. You don't play around with power, especially if that power is your lifeline.
Check the specifications of each circuit breaker, make sure it fits your aircraft, and feel confident that what you receive in the mail is a good fit. Remember, whether it's the circuit breaker itself or some related accessory, like lockout rings and button caps, pick up what you need from SkyGeek.
What types of aircraft circuit breakers are available at SkyGeek?
SkyGeek carries a wide range of aircraft circuit breakers to choose from, including many from leading circuit breaker manufacturers. Order TE Connectivity and Crouse Hinds breakers in one convenient location. Whether you're looking for push-pull, toggle or resettable panel circuit breakers, there’s plenty of options to choose from at SkyGeek.
How do circuit breakers protect an aircraft’s electrical system?
A circuit breaker lock on clip or toggle system is designed to trip when excessive current flows, preventing damage to wiring and onboard systems under unusual circumstances. Always on duty, the aircraft circuit breaker keeps an eye on everything and steps in before trouble starts. It’s especially important in flight where failures aren’t an option — whether you’re in a Cessna or cruising over the aerodrome in a jet liner.
What should I consider when choosing a circuit breaker for my aircraft?
When choosing a base circuit breaker, consider the amperage, voltage rating and compatibility with your DB panel wiring. Also, think about mounting needs. Aircraft circuit breaker collars and circuit breaker collars can be useful for both safety and identification.
Are SkyGeek’s circuit breakers resistant to vibration and extreme conditions?
Yes. SkyGeek’s aviation circuit breaker options are built tough for altitude, heat, cold and persistent vibration. They meet rigorous aviation specs and are tested for reliability in all flight conditions, so you can shop with confidence.
How often should circuit breakers be replaced?
Replacement depends on cycles and wear, but as a rule of thumb, test them regularly and replace them if you notice erratic behavior.
Do I need lockout options for safety?
Yes. Consider a lockout for breakers during maintenance to prevent accidental reactivation. This simple step will enhance safety during maintenance procedures and keep you in compliance.
What type of circuit breakers do aircraft have?
Aircraft typically use thermal, magnetic, or thermal-magnetic circuit breakers. Thermal types respond to heat from overloads, while magnetic breakers trip instantly during short circuits. The combined thermal-magnetic design offers reliable protection for modern aviation electrical systems.
Who makes circuit breakers for aircraft?
Leading aviation circuit breaker manufacturers include Klixon (Sensata Technologies), TE Connectivity, E-T-A, Honeywell, and Eaton. These brands produce lightweight, high-reliability breakers designed to meet the strict performance demands of aircraft systems.
What are the three basic types of air circuit breakers?
The three main air circuit breakers are plain air, air blast, and cross-blast types. Each uses air to extinguish electrical arcs, with air-blast and cross-blast models offering faster, more efficient protection in high-voltage environments.
What causes an ACB to trip?
An Air Circuit Breaker (ACB) trips when it detects overloads, short circuits, or earth faults. These conditions create excessive current or heat, prompting the breaker to cut power and protect the electrical system from damage.
