Working Principle & Protection Mechanism
★ Thermal Protection (Overload)
The thermal element within the DAM1 series uses a bimetallic strip that bends when heated by sustained overcurrent (> rated current). By adjusting the thermal setting between 70% and 100% of In, users can tailor the breaker’s response time to prevent nuisance trips while ensuring effective protection.★ Push-to-Trip Button
For testing purposes, the push-to-trip button allows manual tripping of the breaker, verifying its operational integrity without needing to induce an actual fault condition.★ Separate Main and Arcing Contacts
To enhance durability and performance, the DAM1 series features separate main and arcing contacts. This design ensures that the main contacts are protected during high-current events, prolonging the lifespan of the breaker.
Application Scenarios
The DAM1 Thermal Adjustable Moulded Case Circuit Breaker (MCCB) is ideal for a wide range of applications where precise control over overload protection is essential. These include:
★ Industrial Plants: Ensuring stable operation in steel mills, chemical plants, and oil platforms.
★ Commercial Buildings: Protecting electrical systems in shopping malls, office buildings, and hotels.
★ Utilities: Reliable distribution in substations and power grids.
★ Data Centers: Maintaining uptime in critical IT infrastructure.
