BlockMaster Introduces New High-Power One-Pole Blocks for DIN Rail & Panel Mount

New High Power Blocks for DIN Rail or Panel Mounting

This new HP-ATB-175B Series provides a convenient means of transitioning larger gauge, high-power mains to same size or lower-power branch circuits.

The new HP-ATB-175B Series high-power blocks are rated 175 Amp and 600 Volt for electrical applications in power panel distribution. These new High Output Power terminal blocks can also be used for lighter power applications, and therefore have extended utility as a “one size fits all” product line.

These new blocks provide a convenient means of transitioning larger gauge, high-power mains to same size or lower-power branch circuits.

Applications include:

  • HVAC equipment
  • Pump Control Panels
  • Solar & Wind Power
  • Motor Controls
  • Switch Gear
  • Lighting Panels
  • Elevator Systems
  • Other Industrial & Commercial Applications

Six modular termination configurations, that may be DIN rail or panel mounted, allow you to configure your wiring requirements to each job. These power blocks may be ganged together in any combination or used individually.
