Power switch 3P, 50kA, electronic release EB2 1250/3LE 1250A 3P 004672230

Compact power circuit breaker for demanding applications

This three-pole power circuit breaker with a rated current of 1250A and a short-circuit breaking capacity of 50kA, equipped with an electronic trip unit, provides reliable protection for electrical installations. It is designed to protect cables, power leads, motors and electrical equipment from the effects of overloads and short circuits. The electronic trip unit ensures precise and fast response to current changes, minimizing the risk of damage and downtime.

The EB2 1250/3LE circuit breaker is characterized by a wide range of overload (500…1250A) and short-circuit (7000…15000A) trip unit settings, allowing it to be adapted to the specific needs of the installation. The device's design, as a complete unit in a housing, simplifies installation and ensures durability. The IP20 degree of protection guarantees safe use in environments with limited exposure to moisture and dust.

Functionality and application

This circuit breaker is used in a variety of industrial, commercial and energy installations. Thanks to its high short-circuit breaking capacity, it is ideal for high-power supply systems where reliable protection against the effects of sudden overvoltages is required. The ability to mount additional accessories – such as time-delay trip units or remote control – expands the functionality of the device and allows it to be adapted to individual user needs. Cable connection is made via busbar connection, ensuring a secure and stable electrical connection.
