Mack MD Electric medium-duty truck now available for order

Mack Trucks has announced that dealers are now taking orders for the Mack MD Electric, the brand’s first medium-duty electric vehicle.

The MD Electric is designed to complement the diesel Mack MD, introduced in 2020. The company’s first EV was the Mack LR Electric, which began production in December 2021.

The new truck, which is exempt from the 12% federal excise tax, is available in a Class 6 model with a GVWR of 25,995 pounds and a Class 7 model with a GVWR of 33,000 pounds. It is powered by nickel manganese cobalt oxide lithium-ion batteries in either a 150 kWh or 240 kWh configuration. It will be manufactured at the company’s Roanoke Valley Operations in Virginia.

“Mack is committed to moving toward a more sustainable, decarbonized future,” said Jonathan Randall, President of Mack Trucks North America, “and the MD Electric is just another step in our journey.”

Littelfuse introduces Residual Current Monitor product line for EV charging stations

Circuit protection specialist Littelfuse has introduced its Western Automation Research and Development Residual Current Monitor (RCM) product line to detect AC and DC ground fault currents in EV charging installations.

When a residual fault current occurs, the RCM sends an output signal that triggers a relay or contactor to shut off the supply power and remove the shock hazard during charging. These products may be used to detect AC, DC or both types of faults in single-phase or multi-phase installations.

The new RCMs include single-phase and three-phase designs in one component to simplify inventory. Both chassis and board-level mounting options are available for added flexibility.

The RCM product line offers various models to support the global UL and IEC safety standards for EV charging applications, including:

  • Level 2 (UL2231-2)
  • Mode 2 (IEC62752)
  • Mode 3 (IEC62955)

“It is only a matter of time before EVs become a significant proportion of all vehicles—making it paramount that charging applications are safe and reliable,” stated Philippe Di Fulvio, Littelfuse EV Infrastructure Business Development Manager. “The RCM monitor detects AC and DC ground fault currents and quickly triggers a fault output to disable the charging current and remove the shock hazard when charging vehicles.”
