Miniature circuit breaker VA47-29 2P 5A 4,5kA C IEK

Описание

KMI AC contactors of general industrial purpose are designed for load currents from 9 to 95 A (AC-3). Intended for actuating, shutting down and reversing of asynchronous motors equipped with a short-circuited rotor for the applied voltage limited to 660V, remote control of lighting (AC-5a, AC-5b), heating circuits and various low-inductance loads (AC-1), switching three-phase capacitor batteries (AC-6b) and primary windings of three-phase low-voltage transformers (AC-6a). All unit types per load currents limited to 40 A have a single group of auxiliary NO or NC contacts. Types per load currents exceeding 40 A have two contact groups (NO and NC). KMI AC contactors 9-95 A application includes fan, pump, thermal curtain, furnace, overhead-track hoist, unit, lighting and automated load transfer systems control.

Преимущества

  • Electromechanical design, without use of electronic components.
  • The most reliable protection of a person in case of direct contact with live parts.
  • Independent contact position indicator.
  • Wide operating temperature range, from –25 °C to +40 °C.
  • TEST button to check the device operability and correct connections.
  • No power consumption, operability is maintained when neutral conductor is broken.
  • Notched terminal clamps reduce the heat loss and increase mechanical stability of the connection.
  • Quick installation using the latch with double locking.
  • Conditional short-circuit current value is 4.5 kA.
