Main switch (isolator), 80A, 3-pole HIS-80/3 142826

Professional disconnector for power distribution systems

The HIS-80/3 main switch with a rated current of 80A is a three-pole isolation device from the EATON brand, designed for the safe disconnection of power in three-phase installations. The device, with a rated voltage of 415V and a width of 3 modules, is a key component of industrial and building switchboards.

Construction and technical parameters

The device is characterized by a rated breaking capacity of 12.5 kA and a short-circuit strength of 2 kA, ensuring safe operation under load conditions.

The IP40 protection rating protects against access to hazardous parts with a wire diameter greater than 1mm. The installation depth is 69.5 mm, allowing for mounting in standard modular switchboards.

Functionality and operational safety

The switch is equipped with a black control knob that provides clear signaling of the operating state and a secure grip during maneuvering. The device features 3 make contacts and 0 changeover contacts, allowing for direct control of three-phase circuits.

A key function is the possibility of padlock lockout, which prevents accidental switching during electrical installation maintenance. The terminals allow for the connection of conductors with a rated cross-section of up to 50 mm², enabling the safe conduction of high currents without the risk of overheating contact points.

Application and system compatibility

The HIS-80/3 switch finds wide application as a main element in floor distribution boards, control cabinets, and feeder sections for production machinery. Thanks to its high load capacity, it performs excellently in systems requiring reliable power disconnection from high-power consumers.

The product meets the requirements of the international standard IEC/EN 60947-3, which defines the requirements for switches and disconnectors, confirming the full insulating properties of the device and guaranteeing a safe isolation gap in the open state necessary for performing maintenance work.
