F1 series miniature circuit breaker
Product features:
Isolating function:①contact status indicate, rectangle hole green color means contact in the OFF position, red color means contact in ON position ②Have lock slot in the handle, isolation circuit can be locked to avoid switch on③voltage impact resistance can reach 6Kv.
Wire connecting terminal: bus bar and several guide lines can be connected simultaneously.
Outstanding current limiting character: contact scientific design, using electric repulsion, expect short circuit current value can be reduced considerably after get through circuit breaker, impact to electric and equip system can be reduced from expect short circuit current, improve circuit breaker life.
Excellent breaking capacity: Make improvement on contact rapid breaking and arc extinguishing cover technology, the breaking capacity be improved highly, also more safe and reliable in limitation breaking condition, breaking capacity can reach 10000A.
Rapid close: Pre-storage energy institution design, makes contact close rapidly, ensure reliable working during impacted load, extend circuit breaker electric life. Transparent cover design, with indication function.
Function:
Overload protection, short circuit protection, isolation protection
Instantaneous tripping curve:
C type: provide circuit protection for inductive load and high sensitive lighting system
D type: provide circuit protection for high sensitive load or high impact current distribution system
