2. Key Features
High Breaking Capacity
With a fault-breaking capacity of 25 kA at 415V, the LV510303 offers solid protection even in demanding distribution systems with higher fault levels.
Reliable TM-D Trip Unit
Equipped with a thermal-magnetic (TM-D) trip unit that provides reliable protection against both overloads (long-duration overcurrent) and short circuits (instantaneous trips).
Adjustable Thermal Trip
The thermal trip setting can be fine-tuned between 70% and 100% of the rated current, enabling tailored protection based on the actual load conditions.
Full 3-Pole Protection
The 3d configuration means all three phases are protected, ensuring full system coverage in three-phase installations.
Compact and Efficient Design
The breaker offers a space-saving profile with easy integration into electrical panels, suitable for new installations or retrofit projects.
3. Typical Applications
