Overcurrent circuit breaker Icn=15000A / Icu=15kA 3P D 80A HMD380

Overcurrent circuit breaker – reliable protection for electrical installations

This three-pole overcurrent circuit breaker from Hager, with a rated current of 80A and D characteristic, is a key element of every safe electrical installation. It provides effective protection against overloads and short circuits, protecting both devices and the installation itself. The D characteristic makes this circuit breaker ideal for handling impulse loads and devices with motors that generate high inrush currents – without unnecessary tripping during momentary voltage surges.

Solid construction and wide application

The HMD380 circuit breaker is designed for durability and reliability. Flush-mounting simplifies its aesthetic integration into existing infrastructure. A wide operating temperature range (-25°C to 70°C) allows its use in various environmental conditions. The ability to expand with additional accessories, such as locks or phase separators, increases its functionality and adapts it to individual needs. Conductor cross-sections from 1 mm² to 70 mm² (solid core) and 1 mm² to 50 mm² (stranded) provide great flexibility when connecting different types of wires.

Parameters ensuring safety and efficiency

This circuit breaker is characterized by a high short-circuit interrupting capacity (Icn = 15kA / Icu = 15kA), which guarantees a quick response in the event of a failure. Rated voltage 415V and insulation voltage Ui 500V ensure safe operation in standard electrical installations. Protection class IP20 protects against accidental contact, and pollution degree 3 confirms resistance to harsh operating conditions. The rated impulse withstand voltage Uimp is as high as 6kV, which further increases the level of safety. A width of 4.5 modules allows for efficient use of space in the switchgear cabinet.
