NexBlue ZEN 2 Current Sensor MDCS1, Single to Three Phase, Wi-Fi

The MDCS1 belongs to NexBlue's ZEN 2 Single to Three Phase product family and is listed by the manufacturer as its current sensor. As the family name suggests, it is intended for installations ranging from single-phase to three-phase supply. Choosing the brand's own accessory means the part is designed for the ZEN 2 ecosystem rather than being a generic third-party component, which keeps your charging set-up consistent and straightforward to plan.

The specifications list both Wi-Fi and Bluetooth among the sensor's features. Having two wireless technologies on board gives you flexibility in how the device fits into your home network and charging environment. The manufacturer does not detail the exact pairing procedure or app workflow in the specifications provided, so check NexBlue's installation documentation for the recommended set-up steps for your particular ZEN 2 charger.

Estonian winters and warm summer days are both covered by the stated operating temperature range of -25 to +55 °C. That broad window means the sensor is specified to keep working through cold snaps and heat alike, which matters for equipment that sits in garages, utility rooms or distribution boards where temperatures are not always controlled. It is a reassuring figure for anyone planning a charging set-up that needs to run every season.

The MDCS1 carries an IP30 rating. In practical terms, IP30 indicates protection against solid objects larger than 2.5 mm, such as tools and wires, but no specified protection against water. That makes the sensor suited to dry, sheltered locations such as an indoor electrical cabinet or a protected technical space. If your installation point is exposed to moisture, place the sensor inside a suitable enclosure or choose a dry location.

With a net weight of just 0.10 kg, the sensor is a compact component that is easy to handle during installation. The manufacturer also confirms there is no embedded battery, so there is no cell to monitor, replace or dispose of separately over the device's life. Fewer consumable parts mean less to think about once the sensor is in place and doing its job.

The packaging specification lists 8.00 g of paper and pasteboard and 2.00 g of non-PET plastic. It is a modest amount of material for an electronic accessory, which is good news if you prefer to keep household packaging waste down. The product is also registered under WEEE classification CL109:5:2017-04-01 with the WEEE fee applied, so it falls within the standard electronic waste recycling scheme at end of life.

This sensor is aimed at owners of NexBlue ZEN 2 chargers, and at electricians installing them, who need the current sensor accessory from the same product family. It suits homes with single-phase or three-phase supply, indoor mounting locations, and anyone who values Wi-Fi and Bluetooth connectivity. If you are completing or upgrading a NexBlue charging set-up, it is a sensible, great-value addition from the original brand.
