Siemens Contactor, Screw Terminal Type, 8 Auxiliary Contacts - SIRIUS Innovation Series - 3TF6844-0CP7
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
Is this connector insulated?
Yes. Thanks to its enclosed switching, the components of this unit are secured, keeping you safe from electric shocks during installation.
