Power protection: IEC overload relays provide flexible protection for motors
Get overload protection for single and three phase motors, and phase loss protection for all three phase motors with c3controls Series 320 Bimetallic Overload Relays.
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, such as IP20 guarded terminals with dual terminal markings, integral stop button, and direct mounting, help reduce installation costs and enhance equipment features and performance.
The overload relays can be mounted to all contactors (9-105A). Separate mounting adapters are also available for installation on a 35 mm 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. A device identification marker is included for labeling, which simplifies troubleshooting in panels with many overload relays or starters. A multi-function reset button enables the user to select the reset mode, manual or automatic and whether or not to enable the test function.

But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
