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

• Sub-Distribution Panels: Ideal for use as a feeder breaker in distribution boards.

• Motor Control Centers: Protects motor circuits in industrial environments.

• Lighting & Power Panels: Ensures safe distribution in commercial buildings.

• Pumping and Irrigation Systems: Used to protect circuits feeding pumps in agricultural settings.

• Industrial Equipment: Suitable for general-purpose protection of machinery and control panels.

• Backup Generator Panels: Ensures safe isolation and protection of generator outputs
