Blue Sea Systems' New L-Series Solenoid Offers Superior Performance in Harsh Environments
PN 5301/PN 5302 |
The L-Series Solenoid Switch is an excellent choice for remote battery switching. It saves the cost, weight, and difficulty of running long heavy battery cables. It’s a smart alternative to traditional battery switches. To learn more, click here (PDF file: 89KB).

Three practical applications for the CL-Series BatteryLink™ ACR
PN 7600 |
The CL-Series BatteryLink™ ACR is a current-limiting, voltage-sensing relay with adjustable combine and disconnect thresholds. It automatically combines battery banks during the charging cycle, and isolates battery banks when voltage drops below a certain level.
The CL-Series BatteryLink™ ACR also may be used for these practical applications:

Choosing Circuit Protection
You may want to rethink the process that you use to select circuit protection. It’s not as simple as referring to circuit protection standards tables. Blue Sea Systems' engineers identify new factors to consider when selecting circuit protection. Click for more information.
Update
Blue Sea Systems Engineering Contributes to ABYC Standards Revisions
Wayne Kelsoe, Blue Sea Systems Vice President, Research and Development is a member of ABYC technical committees working on two important areas of the Standards.
Battery Switch Standard
The battery switch standard is being revised to give boat manufacturers better guidance in selecting battery switches for engine starting circuits. The Blue Sea System's Engine Starting Standard (PDF file: 35KB), developed in 2001, is being modified to replace or revise UL1107 which ABYC uses as the reference for rating battery switches. The extreme high currents and short durations of engine starting stress were previously not tested in the UL Standard. Manufacturers have created their own tests and make various claims of capacity—some manufacturers rate for repeated pulses totaling approximately 100 seconds, some other manufacturers rate for only a single pulse of 10 seconds or less. Clearly, a commonly-agreed upon standard is needed.
High Current Faults
Also being revised is the standard for circuit breaker operability after an extremely high current fault. The commonly used UL1077 Standard recognizes some circuit breakers as being capable of repeated maximum fault current, and other circuit breakers as "failing safe" but not being reusable after interrupting maximum currents. The devices are not marked according to the outcome of these tests; the fault behavior can be determined only by examining the UL documents.
System design guidance is under consideration that can be used to predict high level faults. In some instances, present standards may be too strict; in other circumstances, even higher stresses may occur than are predicted in the ABYC E-11 Standard.
