Isolating Switch 3P

Model and meanings

Isolating Switch

1. It adopts a modular design structure, allowing flexible and diverse combinations. Made of glass fiber reinforced unsaturated polyester resin, it has high dielectric performance, a high protection level, and safe and reliable operation. The operating mechanism is an acceleration mechanism with spring energy storage and instantaneous release. The isolating switch has a double-break contact structure for instantaneous connection and disconnection, which is independent of the speed of the operating handle.

2. Isolating switches have various structures and operation modes. They are equipped with a window for directly observing the on-off state of the contacts, allowing operations inside, outside, and at the back of the cabinet, as well as front and side operations, and can be wired at the front and back of the plate.

3. SDKC isolating switches have an attractive, novel, and simple appearance, small size, and complete functions, making them the best choice among similar products.

Load isolating switches can work under the following conditions:

1. Altitude does not exceed 2500m;

2. Ambient temperature shall not be higher than 40°C or lower than -5°C, and relative humidity shall not exceed 95%;

3. Environment without explosive medium;

4. Environment without rain and snow intrusion;

Note: If the product is expected to be used in an environment where the temperature exceeds +40°C or is lower than -5°C to -45°C, the user shall inform the manufacturer.

1. The acceleration mechanism with spring energy storage and instantaneous release achieves a fast opening speed of (13.8m/s), which is independent of the speed of the operating handle, greatly improving the arc extinguishing capacity.

2. The shell made of glass fiber reinforced unsaturated polyester resin has good flame retardancy, dielectric properties, carbonation resistance, and impact resistance.

3. The parallel double-break contacts have a self-cleaning function.

4. All contact materials of the isolating switch are copper-silver alloy, with two separate contact surfaces.

5. Large isolation distance.

6. When in the "O" position, the switch handle can be locked with three latches at the same time, reliably avoiding misoperation.

Q: Can the isolating switch be operated with a load?

A: Isolating switches do not have arc-extinguishing capability, so operation with a load is strictly prohibited. Before operating the isolating switch, it is necessary to ensure that the load current in the circuit has been completely cut off by other equipment with arc-extinguishing capability (such as circuit breakers). Only when the circuit is in a state of no load current can the isolating switch be operated safely.

Q: Is professional personnel required for installation?

A: It is recommended to be operated by a certified electrician. Note: When wiring, ensure that the neutral line (N) is correctly connected to the phase line to avoid misjudgment by the frequency converter. An isolating switch must be configured at the incoming line end to meet the safety requirements for maintenance.

Q: How to choose a suitable isolating switch?

A: First, determine whether to choose a high-voltage or low-voltage isolating switch according to the voltage level of the actual application scenario.

Second, the rated current needs to be considered. In addition, attention should be paid to the type and structural form of the isolating switch. At the same time, environmental conditions should also be taken into account. For example, isolating switches used outdoors need to have good waterproof, dustproof, and anti-corrosion properties to adapt to harsh natural environments.

Finally, brand and quality are also important factors. Choosing well-known brands and reliable quality isolating switches can ensure stable performance, a long service life, and reduce equipment failures and maintenance costs.

Q: How to maintain to extend the service life of the isolating switch?

A: Test the switching function monthly, clean the dust on the shell, and check whether the contacts are oxidized. Each year, have the manufacturer's engineers calibrate the mechanical interlock, upgrade the frequency converter program, and replace worn parts.
