Main disconnect switch (isolator), 63A, 4-pole HIS-63/4 142823

Main disconnector – reliable power disconnection

This four-pole EATON HIS-63/4 isolating switch is a key element of any electrical installation, providing safe and reliable disconnection of circuits. Designed for both domestic and industrial applications, it offers high reliability and durability. Its robust construction and compliance with safety standards guarantee protection of the installation and equipment against overload and short circuit.

Functionality and application

The HIS-63/4 disconnector is used to completely disconnect electrical circuits, allowing for safe maintenance or repair work. Its four-pole design allows for simultaneous disconnection of phases and neutral, which is particularly important in three-phase installations. The rated current of 63A and the high breaking capacity of 12.5kA make it suitable for protecting circuits with higher loads. The ability to lock with a padlock further increases safety, preventing accidental switching on during service work.

Construction and characteristic features

The disconnector is characterized by a compact design, occupying only 4 modules in width. Made of high-quality materials, it ensures long-lasting and trouble-free operation. The terminals allow connection of wires with a cross-section of up to 50mm², which facilitates installation and ensures a secure electrical connection. The housing with a protection degree of IP40 protects against contact and ingress of solid objects, increasing safety. The “arrow” symbol on the housing facilitates identification of the device’s function. Additionally, this disconnector can operate with a continuous current of up to 125A, making it a versatile solution for various applications. Short-circuit strength at the level of 1kA provides additional protection in the event of a short circuit in the installation.
