  • What is the difference between different coil duty cycles?

    The continuous duty ratings means that the coil can remain energized indefinitely without damage to the coil. Intermittent duty coils have more power which improves switching characteristics, but because more power is generated than the coil can dissipate, they cannot be energized indefinitely.

  • What is the advantage of using large contacts?

    One of the consequences of using switching DC currents is the erosion of the contact material. There are many parameters that effect arc erosion, contact size being one of them. AMETEK offers a larger contact, on the J46 series, that will improve the life of the contactor in severe switching applications like inductive loads.

  • What is the advantage of using coil suppression?

    Coil suppression helps protect sensitive equipment from the transient voltage (back EMF) generated from the coil during de-energization. AMETEK Prestolite Switch offers optional suppression devices including a resistor, varistor, diode, diode & resistor. The user must take into account that the coil suppression will increase the release time which will reduce the life of the contactor.
