Main switch (isolator), 63A, 1-pole HIS-63/1 142820

Main Disconnector HIS-63/1

The HIS-63/1 main disconnector is an isolating device designed for disconnecting electrical circuits in industrial and commercial installations. It features a single-pole design with a rated current of 63A and a voltage of 240V AC.

Construction and DIN rail mounting

The device is designed for easy installation on a standard TH35 DIN rail, occupying only one module width. Its compact design with a mounting depth of 69,5 mm allows for space savings in electrical switchboards.

The durable mechanical construction guarantees 16000 operating cycles. Screw terminals accommodate wire cross-sections from 2,5 mm² to 50 mm², enabling the connection of both thin control wires and thick power cables.

A busbar with a thickness of 0,8...1 mm ensures stable electrical connections. An additional safety feature is the padlock lockout capability, which prevents accidental switching during service or maintenance work.

Operating parameters and safety

The disconnector is characterized by high safety parameters - the short-circuit strength is 1 kA, and the rated breaking capacity reaches 12,5 kA. These values guarantee effective operation even under fault load conditions.

The device maintains a high continuous current up to 125A. The IP40 protection class protects against finger contact and access to hazardous parts with a wire.

The single-pole configuration with one make contact allows for precise control of individual circuits. An arrow symbol printed on the device provides intuitive identification of the energy flow direction.

Compliance with standards and operational advantages

The HIS-63/1 disconnector meets the requirements of European standards for devices intended for electrical power distribution. The switch function allows not only for isolation but also for active disconnection of the circuit during normal installation operation.

Its application in AC systems with a voltage of 240V is suitable for single-phase installations.

The ability to use thick wires up to 50 mm² eliminates the need for additional intermediate elements when powering loads with higher current consumption.
