Common Concerns Answered
Is this a continuous duty solenoid or a magnetic latching solenoid?
The Blue Sea 7701100 is a magnetic latching (bi-stable) solenoid, meaning it consumes no power when in either the ON or OFF state, unlike continuous duty solenoids which draw current continuously to remain engaged.
What are the implications of some users preferring a higher intermittent rating?
While this solenoid offers a robust 700A intermittent (5 min) rating suitable for most high-crank applications, users requiring exceptionally long or high-demand cranking periods might consider the specific duty cycle of their engine starting system against this rating.
Is the initial cost higher than simpler solenoids?
While the initial investment may be higher than basic continuous-duty solenoids, the significant long-term battery savings and enhanced reliability of the magnetic latching technology offer a superior total cost of ownership for critical marine applications.
Frequently Asked Questions
What is a magnetic latching solenoid?
A magnetic latching solenoid, also known as bi-stable, uses a momentary pulse of electrical energy to change its state (ON or OFF) and then maintains that state without drawing any further current. This is fundamentally different from a continuous duty solenoid which requires constant power to stay engaged.
What is the continuous amperage rating of the Blue Sea 7701100?
The Blue Sea 7701100 ML Solenoid has a continuous amperage rating of 500A, making it suitable for high-demand electrical loads.
What type of connector does the Blue Sea 7701100 use?
The Blue Sea 7701100 utilizes a Deutsch DTM connector for its control circuit connection, providing a robust and environmentally sealed interface.
Can this solenoid be used for engine starting loads?
Yes, this solenoid is specifically designed and rated for engine starting loads, offering a 700A intermittent (5 min) rating to handle the high surge current required during engine cranking.
What is the intermittent amperage rating of this solenoid?
The Blue Sea 7701100 has an intermittent amperage rating of 700A for a duration of 5 minutes, which is crucial for handling peak loads such as engine starting.
