100A & 200A Contactors

Latching Contactors 100A & 200A Intellitec manufacture a range of heavy duty DC latching contactors, which are used in many different applications. With well over a million of these in constant use, the Intellitec contactors offer a cost effective and extremely reliable solution to high current DC switching in specialist vehicles. Key Features •Latching Mechanism •Draw No Power Open or Closed •Specifically Designed For the Automotive Sector •Reliability •Approved By Paccarr Corporation Intellitecs 100A & 200A contactors provide simple, safe and reliable means of remotely isolating automotive batteries. These unique latching contactors, developed specifically for the automotive sector, are capable of carrying heavy currents. They require NO power to stay open or closed. The Intellitec contactors only draw power during activation. They are sealed against the environments and are designed to withstand the shock and vibration experienced within commercial vehicle, trailer, coach, bus or boat applications. The Intellitec 100A / 200A contactors are mechanically latching switches that operate by the momentary application of battery voltage to the coil terminals in one direction for latching (closed) or the opposite direction for unlatching (open). To close the contactor +12 /24v volts is applied to the 'I' terminal and earth to the 'S' terminal of the contactor. When this is done, a plunger is pulled into the coil and the contacts are connected. While this happens a rod magnet suspended above the plunger is attracted to the top of the plunger by the magnetic field. When the voltage is removed from the coil, the plunger gets pushed upward by a return spring, but cannot move because the rod magnet is in the way. To open the contactor, +12/24v volts is applied to the 'S' terminal and earth on the 'I' terminal. When this is done, the plunger is again pulled into the coil, However, since the magnetic polarity of the coil is reversed, the rod magnet is repelled (like poles oppose), and swings out of the way. When the voltage is removed from the coil, the plunger gets pushed upwards by the return spring, breaking the connection between the two large terminals. Part No's.
