Ambient Temperature

◆-35°C-+70°C, the Average Value of 24 Hours Does Not Exceed +35°C. Users Need to Reduce Capacity When It Is Higher than +40°C. for More Information about the Capacity Reduction Coefficient, See "Ndm2 Molded Case Circuit Breaker Temperature Change Capacity Reduction Coefficient Table"

Storage Temperature

◆ -40°C-+75°C

Altitude

◆ the Altitude of the Installation Site ≤ 2500M High Altitude Capacity Reduction Coefficient See "Ndm2 Molded Case Circuit Breaker High Altitude Capacity Reduction Coefficient Table"

Use Relative Humidity/Store Relative Humidity

◆ the Relative Humidity Does Not Exceed 50% When the Ambient Temperature Is +40°C, and the Lower Temperature Can Have Higher Humidity, Such: the Relative Humidity at 20°C Can Reach 90%, and Corresponding Measures Should Be Taken for Frost Caused by Temperature Changes

Product Introduction

NDM2 series plastic shell circuit breaker (hereinafter referred to as Circuit Breaker), the product is suitable for AC 50/60Hz, rated working voltage to AC690V, the circuit rated from work current to 800A is used for infrequent conversion and infrequent motor startup.
