Genuine Part
Genuine: Original manufacturer part. This product is the original part designed and produced by the vehicle manufacturer.
Spanningsafhankelijke schakelaar - een spanningsafhankelijk relais van 45 ampère dat wordt gebruikt in de extra laad- en accessoirecircuits van het voertuig.

De schakelaar bewaakt de systeemspanning en sluit de hoofdcontacten zodra de waargenomen spanning boven de drempelwaarde stijgt, waardoor een secundair circuit alleen online komt terwijl het laadsysteem actief is. Het wordt gebruikt om het gescheiden laadcircuit, de voeding van de verwarmde achterruit en het relaiscircuit van de airconditioning te regelen, waarbij de hoge stroombelasting wordt geschakeld op basis van de bewaakte spanning in plaats van een handmatige voeding.

Frequently asked questions

What does the PRC4427 voltage sensitive switch do?
The PRC4427 is a 45-amp voltage-sensitive switch that closes a high-current circuit once system voltage rises above its threshold. It brings a secondary load online only while the charging system is active, switching on monitored voltage rather than a manual feed.
Which circuits does the 45A voltage sensitive switch control?
The 45A voltage sensitive switch controls the split-charge and heated rear window circuits on the Defender, and the air conditioning relay circuit on Range Rover Classic. It energises these high-current loads when the charging system raises system voltage.
Which Land Rover models does the PRC4427 fit?
The PRC4427 fits the Defender 1987-2006 (VIN DA310169 to MA962814), Discovery 1 1989-1998 and Range Rover Classic up to 1994. Check your VIN against the chassis ranges, as Range Rover Classic 1992-1994 covers VIN JA610294 to JA624780.
How many voltage sensitive switches are needed?
Typically one voltage sensitive switch is fitted per controlled circuit. A vehicle usually needs a single PRC4427 for its split-charge or heated rear window supply, though setups running several auxiliary circuits may use more than one.
