Description

DMX³ 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 2500A.

Product characteristics
  • Breaking capacity of 50kA, according to EN/IEC standard 60947 - 2, suitable for protection of high power industrialinstallations. Rated insulation voltage of 1000VRated impulse withstand voltage of 12kV
  • Climatic condition according to IEC/EN 60947 - 1 Annex Q, Cat. F subject to temperature,humidity, vibration, shock and salt mist.
  • Electronic protection module ot type MP4 (adjustments accomplished by selector switches) or MP6 (adjustments through touchscreen). Thermal protection within range of 0,4 - 1,0 of the rated current.Magnetic protection within range of 1,5 - 10 of the rated current.
  • Can be equipped with releases (undervoltage and shunt releases) and auxiliary contacts.Can used with rotary handles or motor operator.Locking accessories are available.
  • Has diffent type of possible connection accessories: cage terminals, spreader and rear terminals.Is available also in a plug-in version (circuit breaker fitted with special terminals and mountedon a plug-in base) or in a draw-out version (a plug-in version fitted with a"Debro-lift" mechanism which can be used to withdraw the breaker whilekeeping it on its base)

The product's benefits

Installation
  • Electric and mechanical robustness, in addiction to breaking capacity and chances of accessorizing, are perfectly suited for increase continuity service looking at the plant energy efficiency and in respect of “green aspects”
Usage
  • DMX³ platform provide a complete "project" approach in premiummarket segment, offering a range completely suitable for high powerapplication
