Switches With Electromagnetic Opening TRIZ Cases
- Remote Breaker Handle Mechanism for Fast Contact Closure
A solenoid- and motor-driven handle mechanism speeds breaker contact opening and closure while adding lockout protection for remote operation.
- Levitation Fuse Contacts With Pyro Triggered Overcurrent Interruption
Magnetic contact levitation raises resistance at threshold current, steering current to a pyro trigger for fast, predictable fuse blowing.
- Levitation Fuse Contact Separation for Fast Overcurrent Tripping
Magnetic contact levitation raises resistance and triggers a pyro feature, enabling faster, more reliable overcurrent circuit interruption.
- Multi-Coil Line Protection for Compact Fault and Arc Detection
A shared multi-coil trip structure adds overload and arc detection without extra bulk or bimetal heating in line protection.
- Levitation Fuse Contact Separation Using Magnetic-Pyro Tripping
A magnetic actuator lifts fuse contacts at threshold current, increasing resistance and triggering a pyro break for reliable overcurrent protection.
- Magnetic Circuit Interrupter Dual Solenoid Trip Mechanism
Segmented solenoids allow the circuit interrupter to distinguish high current spikes from prolonged low current loads, preventing accidental tripping.
- Circuit Breaker Actuator Micromotion Detection
Detection unit monitors drive movability through micromotion activation, confirming functionality while maintaining insulating properties.
- Direct Electromagnet Latch Attraction Circuit Breaker
A direct electromagnet attraction eliminates intermediate solenoid linkages, reducing response time and volume while maintaining reliable fault detection.
- Switching Device With Magnetic Latching For Ground-Fault Interrupters
A switching device uses a permanent magnet and yoke to latch the operating member in the ON position against biasing force.
