RVD-EMR Caravan Main Safety Switch

Description

For use with Caravans, motor homes and relocatable homes.

The Residual Voltage Detection Unit (RVD-EMR) is designed for use in TN (M.E.N)/TT electrical earthing systems to enhance electrical protection to any electrical distribution system already protected by an RCD/RCBO unit. The RVD-EMR is a technology that detects a leakage voltage to earth/frame of greater than 43 volts. When the RVD-EMR unit detects an earth/frame voltage above the specification, the RDV-EMR causes the electrically connected RCD/RCBO to trip and isolate the supply voltage to the load. The RVD-EMR provides two (2) additional layers of electrical protection.

1. Overcomes conventional issues with protective devices usually caused by environmental factors including high impedance environments such as sandy, hard rocky soils, wet electrical areas, unearthed electrical supplies, portable generators and power inverters.
2. Detects and trips the RCD/RCBO when the Supply Neutral and Active are swapped.
