Ürün Açıklaması
MZ6T Series | PTC Thermistor Dedicated for Motor Protection
Product Overview
The MZ6T series is a wire-harness type PTC thermistor designed in accordance with international standards DIN 44081 / 44082, specially developed for over-temperature protection of motor windings and bearings. Embedded in the three-phase windings of motors, its resistance rises sharply when the temperature approaches the insulation class limit. Combined with a protector to cut off the power supply, it realizes rapid protection against overheating, overload and phase loss. It serves as a standard core temperature control component for industrial motors.
Working Principle
Low resistance at room temperature(R25 ≤ 100Ω / 300Ω), recognized as normal status by the protector;
When the motor overheats and the temperature reaches the operating temperature Tk, the resistance changes sharply to the kilo-ohm level;
Once the protector detects the high-resistance signal, it trips and shuts down immediately to prevent motor burnout;
The resistance automatically drops after cooling down. No replacement is required, and repeated use is available.
Core Features
✅ Standard Compliance: Compliant with DIN 44081/44082, compatible with mainstream temperature control modules (e.g. INT69);
✅ Ultra-compact Size: Chip size only 1.8×0.6 mm, easy to embed into windings without affecting insulation performance;
✅ Fast Response: Operates within ＜5 seconds under thermal overload or phase loss conditions, much faster than traditional thermal relays;
✅ Precise Temperature Control: Tk ranges from 60℃ to 180℃ (5℃ interval), tolerance ±5℃, perfectly matching motor insulation classes (Class B / F / H);
✅ Long-term Stability: Adopts ceramic substrate and insulated packaging, featuring vibration resistance, aging resistance and long service life;
✅ Flexible Installation: MZ6T adopts long lead wire harness design, suitable for winding embedding, bearing surface mounting and other working conditions.
Typical Applications
Industrial motors, water pump / fan motors, compressor motors;
Servo motors, stepping motors, new energy vehicle drive motors;
Transformers, reactors, high-power inductive coils;
Other electromagnetic equipment requiring overheating, overload and phase-loss protection.
