Three-pole TMF release provides precise thermal-magnetic protection, translating into faster fault isolation and reduced downtime in busy switchboards. With measured trip characteristics, system operators can rely on predictable performance during overloads, preventing nuisance trips and ensuring continuity for critical machinery. Front-terminal connection simplifies wiring and reduces field assembly time, improving heat dissipation paths and minimizing wiring errors in compact enclosures for both new builds and retrofit projects. Rated current of 16 A suits small-to-medium distribution circuits, while a 690 V insulation rating and 550 V DC operating voltage offer versatile protection for mixed loads. High Ics and Icu values ensure resilience for transformer and generator protection in challenging industrial environments. Durability figures show electrical endurance of 1500 cycles and mechanical durability of 8500 cycles, delivering long service life and lower maintenance costs. Rugged, front-connection design aligns with IEC standards and supports quick commissioning with available wiring diagrams and manuals.

FAQs
Front-terminal connections simplify wiring, reducing installation time and minimizing connect-and-test steps in panel builds. The design supports straightforward alignment with standard DIN rail layouts, improves heat dissipation pathways, and lowers the risk of wiring errors during commissioning. Ensure adequate clearance for front-access terminals and use appropriately rated conductors per the 690 V insulation rating.
TMF combines thermal and magnetic trip actions to provide coordinated overload and short-circuit protection. This yields predictable tripping behavior under overloads while rapidly clearing faults during high-energy events. For transformers and generators, TMF helps prevent nuisance trips and enhances reliability in dynamic load conditions typical of industrial installations.
Yes. With a Rated Operational Voltage up to 550 V AC and a Ui of 690 V, plus Ics up to 50 kA at 240 V and Icu up to 100 kA, it is designed for transformer protection in low-voltage distribution. The 3P configuration and front-terminal design support easy integration into transformer feeder cabinets and protection panels.
The unit carries IEC-based conformity with CE labeling, RoHS compliance, and TSCA declarations. Documentation includes the EC Declaration of Conformity for Formula A1, wiring diagrams, and product datasheets, ensuring regulatory alignment across regions and ready reference for audits and supplier qualification.
With electrical durability rated at 1500 cycles and mechanical durability around 8500 cycles, the MCCB offers long service life with reduced maintenance demands. Its front-terminal design accelerates installation and future upgrades, while robust protection reduces downtime from faults, delivering favorable total cost of ownership in manufacturing plants and process lines.
