Request For Quotation The Switch Is Automatic, Three-Pole With Electromagnetic And Thermal Release.

Automatic Switch 700A, Three-Pole With Electromagnetic And Thermal Release. Rated Operating Currents Are In The Range Of 250-630A. Combination Circuit Breaker Release. The Operating Currents Of The Electromagnetic And Thermal Releases Are Adjustable In The Range Of 250-700 A. The Accuracy Of The Operating Current Adjustment Is +/-15%. The Tripping Currents Of The Releases Are Not Regulated During Operation. The Manual Switching Mechanism Ensures Instant Closing And Opening Of Contacts. The Switching Speed Does Not Depend On The Speed Of Movement Of The Handle. All Sections Are Controlled By One Handle. The Handle Has Four Positions: On/Off. Manually, Actuation, Cocking After Actuation. Three Arc Extinguishing Chambers Are Built Into The Circuit Breaker. The Total Weight Of The Switch Is 17-19 Kg. Designed For Maximum Current Protection Of Electrical Installations During Overloads And Short Circuits In Circuits With A Rated Voltage Of Up To 500 V Ac, Frequency 50-60 Hz, For Infrequent (Up To 6 Times Per Hour) Operational Switching Of These Circuits, As Well As For Protecting Electrical Circuits When The Voltage Drops To An Unacceptable Value. If A Short Circuit Occurs In The Electrical Circuit, The Circuit Breakers Operate Instantly. During Overloads, The Operating Principle Of These Devices Is Somewhat Different: Their Response Time Has An Inverse Relationship With The Current Strength. Series A Switches Are Distinguished By Their Reliability And Long Service Life. The Machines Are Manufactured In Climatic Version - U4. Area Of Application: The Standard Design Of The Switches Assumes Their Use In Areas With A Temperate Climate (Maximum Permissible Air Temperature 40°C). The Scope Of Application Of The Machines Is Industrial And Transport Enterprises, Public Utility Facilities Gost Iec 60947-2-2014. Before Shipping, It Is Mandatory To Agree With The Customer.
