An RCCB\/RCD protects against earth leakage by monitoring current imbalance. The two are complementary and are normally installed together in a distribution board.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhat does the Type C tripping curve mean?\u003c\/strong\u003e\u003cbr\u003eType C trips at 5–10x rated current, giving enough headroom for motors, transformers, and ballast\/LED-driver inrush without nuisance tripping.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhat does the 10kA breaking capacity mean?\u003c\/strong\u003e\u003cbr\u003e10kA is the maximum fault current this MCB can safely interrupt without damage.
