Feature:1. FUNCTION AND ROLE: The circuit breaker is used in a separate housing with fuse holder (125A) and surge protection as a shut off option before introducing the housing. The function of dual power supply can be used in generator and mains conversion or solar power and mains conversion2. VARIOUS PROTECTION: The DC isolator switch is used to protect the circuit from overcurrent damage caused by overload or short circuit. The quick release ensure reliable operation of the load and extend the service life of the electrical circuit breaker. Can also act as a switch for the DC load circuit3. WIDE SCENARIO: This DC fuse 125A is very suitable for DC system such as solar power system, small power system, communication system and photovoltaic system. Widely used in grid connected solar panel system, wind solar complementary system and other DC systems. Easy to install on DIN rail(not include)4. SAFE AND FLAME RETARDANT: DC isolation switch has a strong flame retardant housing and fire prevention performance, flame retardant and easy to carry, possess long service life and high stability5. SOLID AND STABLE: PV array DC isolator switch adopt integrated square shaft through multi pole handle design, better synchronization when parting and closing. Six rivets are riveted firmly to avoid cracking of the shell after wiring6. EFFECTIVE WELDING: Din DC isolator switch adopt the welding process, adding silver solder high temperature fusion, bring low temperature rise, short time high current resistance, short circuit closing abilitySpecification:Item Type: DC Isolator SwitchModel: SEG-125Material: PA66Rated Voltage: AC 400VRated Current: 125AIsolated Voltage: DC AC 12-1000 VFunction: 3 level, mains - off - generator(or photovoltaic solar)Impact of Contact Parameters On Products:"Wide Opening": Can withstand greater voltage resistance and extinguish arcing more easily"Super Range": The contact can resist more electrical erosion to ensure the normal use of the product"Final Pressure" - Greater final pressure cause closer contact and lower temperature rise.Package List:1 x DC Isolator Switch
