Use this contactor from Siemens to change over and control slip-ring motors, capacitors and transformer loads. It has a product size of 14 and a 3-pole AC-3 utilisation category for starting and switching off squirrel-cage motors. The improved contact system and current-carrying design provide reliable electrical and mechanical durability. An operating current rating of 700A and service power of 335kW means this component is energy efficient and keeps heat emission to a minimum. Eight auxiliary contacts (4NO+4NC) mean it supports additional actions whenever it's energised. You'll find devices like this used in electric vehicles and solar power generators.

• Erosion indicator shows the condition of contacts for easy maintenance
• Voltage limiter avoids repeated arc striking for safety
• Compact dimensions of 230 (W) x 232 (H) x 237mm (D) for easy handling
• Wide operating temperature range between -25°C and +55°C for use in challenging conditions
• Screw termination for simple installation without drilling holes

Yes. Thanks to its enclosed switching, the components of this unit are secured, keeping you safe from electric shocks during installation.
