B-P MARINE Voltage Sensitive Relay - 12v - 125 Amp
Automate battery connection during charging with the B-P Marine 12V voltage-sensitive relay, part 700078. It senses the supply voltage and operates at defined combine and open thresholds, providing a relay-based approach to managing the connection between circuits.
This model combines at 13.7V and opens at 12.8V. Those thresholds identify its switching behaviour and should be compared with the charging system you intend to use. Its continuous current rating is 125A, with a separate intermittent figure listed below.
The B-P Marine unit automatically joins two batteries when charging and separates them when charging is no longer present. It uses a robust glass-fibre-reinforced nylon enclosure and offers surface or panel mounting options. The LED illuminates when the relay engages.
The engagement indicator is useful when checking the operating state at the unit. Plan its position so that the connections can be made properly and the indicator can be seen when inspecting the installation.
A voltage-sensitive relay works as part of the wider charging and battery arrangement. Match the nominal 12V system, switching thresholds and load ratings with that arrangement before installation. The relay’s operating figures should be kept with the exact model when comparing alternatives.
The stated standby and engaged current-consumption figures allow you to include the relay itself when assessing the electrical system. Its relay connection avoids the forward voltage drop associated with diode-type battery isolators.
Surface and panel mounting options allow the relay location to be planned around the available support and wiring route. Its reinforced nylon enclosure forms the physical body of the unit, while the relay itself performs the automatic combine-and-isolate function.
