Rated Parameters and Mechanical & Structural Parameters
I. Rated Parameters
- Rated Voltage (Ue): It represents the system voltage level suitable for the isolating switch. Common values are AC 230V, 690V, etc. The label of this product indicates that the rated voltage is 230V, which means it is applicable to circuits of this voltage level.
- Rated Current (In): This is the maximum current that can be continuously carried under normal working conditions. In the model XYRMGL-63/4P, the "63" most likely refers to a rated current of 63A.
- Rated Insulation Voltage: It is the voltage value that can ensure the insulation performance of the isolating switch, and it is closely related to the electrical safety of the product.
- Rated Impulse Withstand Voltage: It refers to the value of the instantaneous overvoltage impulse that the switch can withstand.
II. Mechanical and Structural Parameters
- Number of Poles: The "4P" in the product model represents four poles. This switch is suitable for three-phase four-wire circuits and can isolate three-phase phase wires and the neutral wire simultaneously.
- Operation Mode: Common operation modes include manual operation (such as handle type, rotary type, and lever type) and electric operation. Generally, most load isolating switches adopt manual operation.
- Contact Type: There are types like single-break contacts and double-break contacts. Double-break contacts provide higher isolation safety as they can reduce the arc residue.
- Terminal Type: Examples include screw terminals (which are universal and firmly installed), spring terminals (enabling quick wiring), and plug-in terminals (convenient for modular installation).
