NARVA Voltage Sensitive Relay 12v - 140 Amp
Automate battery connection during charging with the NARVA 12V voltage-sensitive relay, part 700158. 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 13.3V and opens at 12.7V. Those thresholds identify its switching behaviour and should be compared with the charging system you intend to use. Its continuous current rating is 140A, with a separate intermittent figure listed below.
NARVA’s weatherproof IP65 body houses durable silver-tipped contacts. Surge protection is built in, and an LED indicator shows when the relay is engaged. The 67 x 67 x 50mm dimensions help you assess the space needed for the unit.
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 combine and open thresholds differ from other relay models in the range. Select this NARVA version by those values and its continuous rating, as well as the physical footprint, when renewing an existing battery-management component.
The silver-tipped contacts and surge protection are part of this relay’s internal design. The weatherproof body and compact footprint help define its installation format, while the indicator provides a visible check of engagement without substituting for a complete system assessment.
