Product Description

The Cutler-Hammer® A202 Lighting
Contactor from Eaton’s electrical busi­ness provides a safe and convenient
means for local or remote switching of
relatively large tungsten, fluorescent
or mercury arc lamp loads.

Application Description

■ The Magnetically Latched Lighting

Contactors are designed to withstand
the large initial inrush currents of
tungsten lamp loads without contact
welding.

■ The A202 Contactors are fully rated

devices that do not require de-rating
similar to standard motor control
contactors.

■ The Magnetically Latched Lighting

Contactor provides effective control
in applications such as office build­ings, industrial plants, hospitals,
stadiums, airports, etc.

Features

■ Designed and tested specifically for

lighting and resistive loads

■ Easy to install and maintain

■ No control power necessary to

maintain contact closure

Operation

A permanent magnet is built into the
contactor structure that will maintain
the contactor in its energized state
indefinitely without using control
power. When energized, a DC current is
applied to the latch coil, producing a
magnetic field that reinforces the polar­ity of the permanent magnet, pulling in
the contactor. The coil clearing interlock
disconnects the current to the coil. In
order to drop out the contactor, it is
necessary to apply a field through the
STOP coil in the reverse direction to the
permanent magnet. This momentarily
cancels the magnetic attraction and the
contactor drops out.
