MEGABREAK MA08 air circuit breaker draw-out version 3P - In= 800A - Ue= 690Vac - Icu= 50kA - Frame 1. Protection unit type MPX.10
Description

Megabreak air circuit breakers offer optimal solutions to answer to protection requirements on the origin of the low voltage electrical installation (IEC/EN 60364-1) up to 1600A.

Product characteristics
  • Breaking capacity of 42kA, according to EN/IEC standard 60947-2, suitable for protection of high power industrialinstallations.
  • Rated insulation voltage of 1000V. Rated impulse withstand voltage of 12kV
  • Electronic protection module ot type MP2.10 (LED matrix display) or MP4.10 (LCD screen) for common for measurements and settings.Thermal and magnetic protections completely adjustable in times and currents by dedicated software
  • Equipped with auxiliary contacts (1 NO/NC, expandable up to 6 and 1 fault contact) and door sealing
  • Can be equipped with auxiliaries (undervoltage and shunt releases, auxiliary contacts, motor operator), locking accessories and connection accessories (spreaders, rear terminals, insulation shields, interlocks)
Recommendations / Restrictions
  • Must be equipped with electronic protection unit (to be ordered together for factory assembled)
Products benefits
Installation
  • Can be mounted on plate in Legrand cabinets and enclosures. Can be converted in a draw-out version with base and conversion kit
Usage
  • Device real-time monitoring and testing through EnerUp + Project App is possible directly from smartphone, using the MPXX02 dongle key
Advantages
  • Perfectly suited for increase continuity service looking at the plant energy efficiency and in respect of “green aspects”
  • The product can be configured to adapt the project needs (1:1 to 1:N), total freedom to design a proper tripping curve
  • Electric and mechanical robustness, high performance, reliability and strength
