To keep your oil pumps switching like greased lightning, turn to this reversing contactor from Siemens. It's specifically designed for rapid, continuous opening and closing of a heavy current load without wearing down, for an extended service life. Isolation between the unit's coil and main contacts ensures there's minimal risk of power surges causing damage to equipment. This triple-poler is just what you need for three-phase motors that move in both directions, like those found on packaging lines, industrial conveyors and thread-cutting machines. For versatility, you can use it with both AC and DC control circuits.

• Resists shock and vibration, making it compatible with rugged settings
• Opening delay of 60 to 100ms, so has an almost instant switching action
• Rotatable and tiltable for various vertical mounting orientations
• Wide operating temperature range between -25°C and +60°C, so it's suitable to use in harsh environments

Yes, the product is designed for side-by-side mounting with zero spacing in between units, which helps you maximise your board packing efficiency.
