Feature:1. [Flame Retardant Housing] Our circuit breaker is made of nylon material Pa66, which has excellent flame retardant safety performance.2. [Short Circuit Protection] When the circuit is short circuited, the electromagnetic tripping mechanism can stably cut off the current, which is safer to use.3. [Rapid Arc Extinguishing] The circuit breaker can quickly extinguish the arc to avoid electrical fires and ensure your safety.4. [Easy Installation] The circuit breaker is a double locking clip structure, which can be operated horizontally during installation, and can be disassembled and assembled freely in a narrow environment.5. [Wide Application] Miniature circuit breakers are widely used in power distribution protection in civil, commercial buildings and industrial places.Specification:Item Type: Miniature Circuit BreakerMaterial: PA66Rated Insulation Voltage (Ui): 500VACPollution Level: 3Withstand Impulse Voltage (Uimp): 6kVMagnetic Trip:B Curve: (3-5)lnC Curve: (5-10)lnD Curve: (10-14)lnThermal Trip Reference Setting Temperature: 30Use Category: A, in line with IEC60898-1Current Limiting Level: 3Single Pole Breaking Capacity (Icn1): Icn1=Icn(6000A)Protection Class (IEC60529):Circuit Breaker Cody: IP20Installed in the Distribution Box: IP40, insulation class is Overvoltage Category (IEC60364): Damp Heat Resistance (IEC60068-1): Class 2 (at 55C, relative humidity 95%)Wiring Method: Top in and bottom out, bottom in and top outFunction: Short circuit protection, overload protection, control isolationElectrical Life: 10000 timesMechanical Life: 20000 timesAmbient Temperature: -35-70Storage Environment Temperature: -40-85Voltage: 400V.Package List:1 x Miniature Circuit BreakerNote:Pay attention to the safety of electricity when using it, please install it under the guidance of professionals
