Outline and Installation Dimensions
Installation and Usage Instructions
- 1 The switch should be installed vertically. The upper terminals should be connected to the power supply, and the lower terminals are for the load output. Pushing the handle upwards connects the circuit (ON) and shows a red indicator; pulling it downwards disconnects the circuit (OFF) and shows a green indicator.
- 2 Before applying power, operate the switch manually several times. The mechanism action should be flexible, reliable, and without any blockage.
- 3 The switch is allowed to infrequently make and break load currents (including appropriate overloads) when necessary. However, it must not be used to interrupt short-circuit currents.
Frequently Asked Questions
Q
What is the HL30 series isolating switch used for?
The HL30 series is a disconnector (isolating switch) designed to connect and disconnect electrical power circuits. It does not provide protective functions such as overload or short-circuit protection, and is intended for infrequent switching operations.
Q
What rated currents are available for the HL30 series?
The HL30 series is available in four rated current options: 32A, 63A, 100A, and 125A, covering a wide range of application requirements.
Q
How many pole configurations does the HL30 isolating switch support?
The HL30 series supports 1P, 2P, 3P, and 4P configurations. Single-pole (1P) models are rated for 230V, while 2P, 3P, and 4P models are rated for 400V operational voltage.
Q
What type of DIN rail does the HL30 switch mount on?
The HL30 series is designed to mount on a TH35-7.5 standard steel DIN rail. The mounting surface inclination relative to the vertical plane must not exceed 5°.
Q
Can the HL30 isolating switch be used to interrupt short-circuit currents?
No. The HL30 isolating switch must not be used to interrupt short-circuit currents. It is only suitable for infrequently making and breaking load currents, including appropriate overloads when necessary.
Q
What is the mechanical and electrical durability of the HL30 series?
The HL30 series offers a mechanical durability of 8,500 operating cycles and an electrical durability of 1,500 cycles, ensuring reliable long-term performance in standard installation environments.
