Feature: 1. Bilateral busbar wiring capability to accommodate a wider range of uses. 2. Maximum connection capacity 35mm, wiring torsion 3.5N.m, suitable for various installation equipment. 3. Wiring is stronger and thus works more stable. 4. In case of electric shock or grid leakage current exceeding a fixed value, the power can be cut off. In order to protect people and equipment, fault currents in a short time can also be used for infrequent starting of circuits and motors. 5. The circuit breaker is suitable for industrial, commercial, high-rise buildings, homes and other places.Comply with IEC/EN61008.1 Specification: Item Type:Circuit Breaker Maximum Wiring Capacity:35mm Wiring Torsion:3.5N.m Protective Level:IP20 Rated Input Current:25A 40A 63A(Optional) Pole:2P Rated Voltage Ue : 230VAC Insulation Voltage Ui : 500V Rated Frequency : 50/60Hz Rated Sensitivity I△N : 0.3A Rated Residual On-Off Capability Im: 500 (In=25-40A) 630 (In=63A) Short Circuit Current Lnc=L△C : 10000A Disconnect Time I△N : ≤0.1S Rated Impulse Withstand Voltage (1.2/50) Uimp : 6000V Insulation Test Voltage (Within One Minute): 2.5KV Electrical Life And Mechanical Life : 4000 Set The Reference Temperature Of The Thermal Element : 30 ° C Ambient Temperature (Daily Average ≤ 35 ° C): -5~+40 °C Storage Temperature : -25~+70°C Package List: 1 x Circuit Breaker Note: Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering.
