Introduction to MZ31 Series MZ8 Type PTC Electronics

The MZ31 series MZ8 type PTC Electronics is a highly reliable PTC Element designed for overcurrent and overload protection. Known as an "auto restore fuse" or "ten-thousand-time fuse," these PTC Thermistors provide automatic circuit protection with recoverability, allowing for repeated use without the need for manual intervention. It effectively safeguards circuits from abnormal temperature and current conditions without triggers, noise, or sparks, making it an essential component in PTC electronics.

Applications of PTC Electronics for Overcurrent and Overload Protection

The MZ31 series PTC Elementis suitable in many applications for reliable circuit protection such as below:

Overcurrent protection,
Overload protection for digital multimeters, micromotors, and transistors etc.
- Key Advantages of PTC Element
- Automatic circuit protection: Ensures stable recovery after faults.
- Contactless, noiseless, and flameless operation: Enhances safety and reliability.
- Fast response: PTC Thermistors quickly react to abnormal conditions.
- Enhanced overvoltage protection: Superior performance in a wide range of voltages.
- Small steady resistance and rated current: Maintains efficiency in circuit operations.
- RoHS compliant: PTC Electronics friend for Environment and safe for use.

Key Features of PTC Electronics

Working Principle

As indicated in Fig 2 as below,when the circuit is in a normal state, the current passing through the PTC Thermistors remains below the rated current, allowing the PTC Element to maintain a low resistance. This ensures that the normal operation of the protected circuit, such as the primary and secondary loops of a voltage transformer, is not disrupted.

However, if a fault occurs and the current exceeds the rated level, the PTC Electronics rapidly heat up, increasing its resistance. This high resistance effectively "turns off" the circuit, protecting it from potential damage. Once the fault is resolved, the PTC Element automatically returns to its low resistance state, allowing the circuit to resume normal operation.
