Product Description

The HR6 series fuse type isolating switch is mainly used in distribution circuits and motor circuits with rated voltage of AC800V and below, as a power switch, isolating switch, emergency switch, and for circuit protection, but generally not used for directly opening and closing a single motor.

The HR3 series fuse type isolating switch is suitable for use as short-circuit protection and overload protection for cables and wires in distribution systems with AC50Hz/380V rated current up to 1000A. Under normal circumstances, it is possible to manually connect and disconnect normal load current and overload current infrequently. In the event of a short circuit, the current is disconnected by a fuse.

Frequently Asked Questions

Q1: What are the main applications of the HR6 series fuse type isolating switch?

A1: The HR6 series is primarily designed for distribution circuits and motor circuits with a rated voltage of AC 800V and below. It functions as a power switch, isolating switch, and emergency switch for overall circuit protection, though it is generally not used for directly opening and closing a single motor.

Q2: How does the HR3 series isolating switch handle short circuits and overloads?

A2: The HR3 series provides short-circuit and overload protection for cables and wires in distribution systems up to 1000A (AC 50Hz/380V). Under normal conditions, it manually connects and disconnects normal load and infrequent overload currents. During a short circuit, the current is safely disconnected by the fuse link.

Q3: What certification standards do these isolating switches comply with?

A3: The HR6, HR5, and HR3 series isolating switches are fully certified to meet the national and international standards of GB/T 14048.3 and IEC 60947-3, and carry the CCC certification mark.

Q4: What is the configuration difference between auxiliary switch types '0' and '1' in the HR5 series?

A4: In the HR5 series selection guide, type '0' comes with a fuse but without a blown fuse signal device (utilizing a fuse link with a blown fuse indicator). Type '1' is equipped with a blown fuse signal device (utilizing a fuse link with a blown fuse striker).

Q5: Can I get a left-hand operation configuration for the HR3 series isolating switch?

A5: Yes. By selecting the 'Z' option under the special types configuration parameter, you can order a left-hand operation switch. The default mechanism is designed for right-hand operation.

Q6: What does the "BX" operating handle type signify for the HR3 series?

A6: The "BX" specification indicates that the switch is equipped with a rotary operating mechanism. If no handle code is specified, the switch will come with the standard default ordinary handle.
