Lighting Contactors Mechanically Held

Lighting Contactors Mechanically Held use a mechanical latch instead and have a retentive memory. Removal of the voltage from the control circuit allows them to operate quietly and consume a very little amount of control power. They are held in place without the need of a constant power drain. The coil on these types of contactors is far less likely to burn up as it is energized momentarily.

Open
Open Lighting Contactors Mechanically Held are designed to provide a safe, convenient means for local or remote switching of tungsten or ballast lamp loads. They are also suitable for other loads such as low pressure and high-pressure sodium lamp loads and other non-motor (resistive) loads.

NEMA 1 Enclosure
A NEMA 1 Enclosure is for general-purpose. It protects against dust, light and indirect splashing but it is not dust-tight. A NEMA 1 Enclosure primarily prevents contact with live parts. It is used indoor and under normal atmospheric conditions.

NEMA 3R Enclosure
A NEMA 3R Enclosure is weather-resistant. It protects against falling dirt. It protects against weather hazards such as rain, sleet and snow, and it is undamaged by the formation of ice. It is used outdoors on ship docks, in construction work, and in tunnels and subways.
