c3controls' Series 320 Bimetallic Overload Relays
Design News Staff -- Design News, September 4, 2006
Reliable and accurate motor protection
These IEC overload relays offer overload protection for single and three-phase motors, and phase loss protection for all three-phase motors. Installation is cheaper through features like IP20 guarded terminals with dual terminal markings, integral stop-button and direct mounting. They can be directly mounted to all contactors (9A-105A), and separate mounting adapters are available for installing on a 35 mm DIN rail or panel. They come with combination head terminal screws which are compatible with both standard, phillips and posidrive screwdrivers. They also come with a multi-function reset button which allows user-configurable reset modes such as manual or automatic and whether or not to enable the test function. They have single-phase sensitivity, and a device identification marker for labeling.
