Capacitor step 12 a DB109701 DB110656 Choice of products pi A 7 Network voltage Ie peak closing current fe oscillating frequency Capacitor current Capacitor voltage Contactors General Capacitor control is accompanied by transient operating conditions resulting from the capacitor load which amongst other things generates a very high overcurrent equivalent to a short circuit of short duration The use of standard contactors may compromise the safety of persons and installations Telemecanique contactors for capacitor control The LC1 DeK contactors are specially designed for capacitor control They are fitted with a contact block allowing the current to pass on closing and with damping resistors limiting the current on energisation This technology which is unique has been patented Personal safety The contactors cannot be operated manually The contactors are fitted with covers for protection against direct contact Safety of installations The damping resistors are disconnected after the capacitor current energising peak A faulty contactor pole therefore does not allow the permanent current to flow through the resistor and prevents it from burning Simplicity and durability LC1 DeK contactors are a ready to use solution that does not require the installation of shock coils Their durability is far greater than that of conventional solutions 300 000 operating cycles
