New IEC Overload Relays by c3controls

Press release date: Dec 04, 2006

c3controls Series 320 Bimetallic Overload Relays provide overload protection for single and three phase motors, and phase loss protection for all three phase motors. Other features like IP20 guarded terminals with dual terminal markings, integral stop button, and direct mounting will help you reduce you total installation costs and enhance the features and performance of your equipment.

Overload relays by c3controls can be directly mounted to all contactors (9A ~ 105A). Separate mounting adapters are also available for installation on a 35mm DIN rail or panel. Combination head terminal screws allow the use of straight, phillips, or posidrive screwdrivers. Ambient temperature compensation ensures reliable motor protection even in high temperature environments.

Overload relays are equipped with single-phase sensitivity to protect motors against damaging phase loss conditions. Dual IEC and NEMA terminal markings are included for ease of wiring anywhere in the world. c3controls equips them with a device identification marker for labeling, which simplifies troubleshooting in panels with many overload relays or starters.

c3controls Series 320 Bimetallic Overload Relays feature a multi-function reset button enabling the user to select the reset mode - manual or automatic and whether or not to enable the test function. When the reset button is pressed, with the test function enabled, the Normally Open (NO) contact closes and the Normally Closed (NC) contact opens to verify the control circuit functionality. In addition, the NC contact can be used in a "Stop" circuit. With the test function disabled, the NO and NC contacts do not change state when the reset button is pressed - preventing unauthorized personnel from operating the control circuit. These multiple functions in the single device help you to reduce inventory and customize the overload relay operation to provide the performance and features you need for your specific application.

This year marks c3controls' 30th year in industrial controls, which means celebrating thirty years of unparalleled quality, world-class customer care, best pricing, same-day shipping, satisfaction guarantee and an unsurpassed two-year warranty on your control purchases.
