Product Details
MD0630T41A-1 is a high-sensitivity leakage current sensor, which can also be called a residual current monitor (RCM) and residual current device(RCD). The residual current sensor is used as a type B RCD sensor dedicated to DC, AC, or pulsed leakage current measurement in automotive on-board chargers. IVY gives you the choice of having single or three-phase versions as well as safe version in the same housing and providing fast digital tripping output when leakage current is detected.
MD0630T41A-1 differential current sensor is the most important component for In-Cable control boxes (IC-CPDs) or wallboxes for charging electric vehicles. It is intended for the detection of DC and AC residual/fault currents in 50Hz/60Hz AC installations. It will protect against DC (6mA) and AC (30mA) residual currents, and will signal to the Smart EVSE if a fault occurs. The Type A 30mA + DC 6mA leakage sensor has numerous applications and is suitable for many industries include EV charging, PV systems (solar panels), industrial devices, DC screens, fire distribution cabinets, and any installation where there is a risk of DC-current flowing. It is the technology that brings us closest to total protection for all known residual fault currents.

EV Charging Application
IVY offers AC/DC sensitive differential current transformers for charging cable (mode 2), AC wallbox (mode 3), DC charging station (mode 4), and optional in on-board charger applications.
Generally, AC/DC-sensitive differential current sensors can be used where direct current and alternating current circuits are directly connected, and AC/DC leakage currents can occur.
Typically, type A RCCBs are the sole type installed in private households, unable to detect and act on DC fault currents. Therefore, everybody that want to charge an electric vehicle (EV) from a home power supply would require a costly type B RCCB to guarantee safety in the presence of DC fault currents. A differential current sensor integrated into an IC-CPD or wall box provides all-current sensitivity and electrical safety at low
cost and makes the installation of an expensive type B RCCB obsolete.
As the differential currents to be monitored only occur in the event of electrical faults and are extremely low (mA), maximum measurement precision is critical. In addition, a fast response time is required to maintain safety features and prevent humans from getting injured. Differential current sensors fulfill both of these essential requirements.
