Fuse base VV with micro switch VVP 7.2 1P-N + NC 004349019

Medium Voltage Fuse Base – Reliable Installation Protection

The VV fuse base with VVP 7.2 1P-N + NK microswitch is a key element in protecting medium voltage installations. Designed to work with VV fuse links, it provides effective protection against overloads and short circuits. The construction with a microswitch (operation indicator) facilitates quick identification of blown fuse links, significantly reducing downtime and improving diagnostics.

Construction and application

The base is designed for indoor mounting and designed to operate at a rated voltage of 7.2 kV. Its single-pole design (1P-N + NK) makes it ideal for building simple protection circuits. It is worth noting the compatibility with different sizes of fuse links – selecting the appropriate size is crucial for the correct operation of the entire system.

Key features and benefits

• Operation indicator: The microswitch enables visual control of the fuse link status – after the fuse link blows, the indicator clearly signals the need for replacement. This saves time and minimizes the risk of misdiagnosis.
• Solid construction: Made of high-quality materials, it ensures durability and reliability even in harsh operating conditions.
• Compact dimensions: Allow for easy installation even in limited space. The base length is 192 mm and the weight is only 5.1 kg, which facilitates installation work.
• Compliance with standards: The product meets the requirements of PN-IEC 60282-1 (2002-01), which guarantees the safety and proper operation of the protection system.
• Versatility: It can be used both in new installations and in the modernization of existing protection systems.

Installation and operation

Installation of the fuse base requires adherence to safety regulations applicable to work under voltage. Ensure that the voltage is switched off before starting installation work. The selection of the appropriate base should be correlated with the type and parameters of the VV fuse links used. Regular visual checks of the fuse link status using the microswitch allow for quick detection of damage and prevent more serious failures.
