Common Concerns Answered
Why does this switch require separate circuit protection?
The Blue Sea 9019 is designed specifically as a selector switch to manage power sources, not to interrupt overcurrent events. By separating these functions, the design maintains a compact footprint and focuses on reliable source selection, assuming appropriate overcurrent protection devices are installed upstream or downstream as per marine electrical standards.
Can this switch be used for DC systems?
No, this switch is rated and designed exclusively for AC (Alternating Current) applications. Utilizing it in a DC (Direct Current) system would compromise its performance and safety ratings, as DC circuits have different electrical characteristics than AC circuits.
Is this an all-in-one solution for my power management needs?
This switch is an expert-grade AC source selector. While it doesn't integrate circuit breakers, its strength lies in its specialized function, offering a compact and reliable method for choosing between two AC power inputs, ideal when you already have dedicated overcurrent protection in place.
Frequently Asked Questions
What is the maximum voltage and amperage rating for the Blue Sea 9019 switch?
The Blue Sea 9019 switch is rated for a maximum of 240VAC and 63A.
How many positions does the Blue Sea 9019 switch have?
The Blue Sea 9019 switch features an 'OFF' position plus two additional selection positions, totaling three distinct operational states.
Can this switch be used with 120V AC sources?
Yes, while rated for 240VAC, this switch is also suitable for use with 120V AC sources for source selection purposes.
What is the purpose of the 'OFF + 2 Positions' configuration?
The 'OFF + 2 Positions' configuration allows the user to completely disconnect the circuit from both power sources (OFF) or select either of the two available AC power sources.
What is the maximum panel thickness this switch can mount in?
This switch is designed to mount in panels with a maximum thickness of 0.16 inches (4.00mm).
