Detailed description

Designed for 12 V and 24 V marine electrical systems, the BEP 80-701-0018-00 battery switch provides a remote-controlled emergency parallel function. This device is essential for ensuring a critical power source in the event of main battery failure, allowing battery banks to be combined for engine start or temporary power. It is specifically designed for applications requiring only an emergency parallel function, without voltage-sensitive switching (VSS).

Emergency parallel functionality

This battery switch activates a remote emergency parallel function for 10 minutes. This period is sufficient for a critical engine start. After 10 minutes, the connection automatically deactivates. The function can be triggered via a remote momentary switch (not supplied). A manual override option is also included for direct and immediate control.

Design and technical specifications

With a current capacity of 275 A, the BEP 80-701-0018-00 is suited to demanding marine environments. Its construction features tinned copper conductors, stainless steel nuts, and fiber-reinforced plastics, ensuring resistance to high temperatures and extended longevity. The housing is ignition-protected and can be surface-mounted or flush-mounted, offering installation flexibility. Its dimensions are 69 x 69 x 101 mm. For optimal performance and compliance with its rated capacity, a 3/0 AWG (95 mm²) cable is recommended for the connection.

Expert opinion

« Smart and integrated management of marine batteries »

The BEP 80-701-0018-00 battery isolator is a fundamental safety component for any marine electrical system. Its primary purpose is to provide a reliable backup solution in case of failure of a starter or service battery. Unlike voltage-sensitive switches (VSS) that manage automatic charging, this model is specifically dedicated to emergency parallel function, activatable on demand.

Its integration is simple: a momentary switch (not included) allows remote activation of battery paralleling, a valuable feature during critical engine starts. The 10-minute delay provides sufficient time to start the engine, then deactivates. It is imperative that both battery banks are of the same voltage (12 V or 24 V). The robust construction and ignition protection make it suitable for engine compartments.

For installation, adequate cable cross-section (3/0 AWG or 95 mm²) must be provided to handle the 275 A current. The choice between flush or surface mounting offers adaptability to space constraints. This device is ideal for recreational boaters seeking a simple, direct, and reliable emergency function without the complexities of a fully automated battery management system.
