Megnetic Core for MCCB Molded Case Circuit Breaker MCB Miniature Circuit Breaker (YF10005)
A magnetic ring (also known as a ferrite magnetic ring or anti-interference magnetic ring) is a ring-shaped component made of magnetic materials such as ferrite. It is widely used in electronics, communications, electricity and other fields. Its core function is to suppress electromagnetic interference (EMI) by reducing the interference between circuits or devices through the loss and absorption of high-frequency electromagnetic signals.
For Permalloy magnetic cores (μi = 50k) for miniature circuit breakers ≤40/30mA, HAIPART uses a vacuum annealing process to increase the Bs value to 0.8T. The unique three-stage magnetic circuit design reduces the triggering time for 300mA fault current by 0.2ms and ensures a detection accuracy of ±1% for weak 30mA leakage currents.
Why Choose HAIPART Magnetic Core?
✅
Precise permeability adjustment for applications ≤40/30mA
✅
Special suitability for sensitive fields such as medical and new energy
✅
Deeply aligned with the miniaturization trend of IoT devices in 2025
Applications
Suitable for life safety, new energy neural networks, industrial IoT, and other fields.
