Installation clamp - insulated - silver-plated NVLI 2 004941223

Installation clamp isolated – reliability and safety in your installation

This installation clamp, catalog number 004941223, is a key element ensuring the safe and efficient operation of the electrical installation. Designed to work with industrial fuse bases, it allows for creating a visible insulating break in the circuit, which is particularly important during maintenance and repairs. Silver-plated knife contacts guarantee low power loss and minimal heating, and the insulated design protects against accidental contact with live parts.

Characteristics and application

NVLI 2 clamp from the ETI POLAM series, designed for NH2 systems, is a component dedicated to both professional installers and end-users who care about safety. Its main task is to safely connect and disconnect electrical circuits when it is necessary to switch off the power or carry out maintenance work. The clamp design allows for repeated insertion and removal (up to 350 cycles), which increases its durability and reliability. Made of high-impact polyamide, it provides resistance to mechanical damage and weather conditions.

Key features and benefits

• Rated current 400A: Ensures safe operation in circuits with high load.

• Size NH2: Compatibility with popular NH2 fuse bases.

• Silver-plated knife contacts: Minimize electrical resistance, reducing power loss and heating of connections. This translates into greater energy efficiency and longer component life.

• Insulated design: Increases safety, protecting against accidental contact with live parts – important for installers during installation and for end-users in the event of a failure.

• High-impact polyamide: The housing made of durable plastic provides resistance to mechanical damage and external factors.

• Compliance with PN-IEC 60269-2:2008 standard: Guarantee of meeting stringent safety and quality standards.

• Reusable: The clamp can be repeatedly inserted and removed (up to 350 cycles), which increases its functionality and cost-effectiveness.

Remember that a special insulated handle (e.g., R 00-3 or VR 00-3) is recommended for safe installation and removal of the clamp.
