3-pole isolator for flat busbars BBS-3/FL 107066

Flat busbar isolator – safety and reliability in your installation

This 3-pole flat busbar isolator BBS-3/FL from Eaton is a key element ensuring the safe and efficient operation of the electrical installation. Designed for 60 mm systems, it allows you to isolate circuits, which is essential during maintenance, repairs or modernization. Its solid construction and high resistance to environmental conditions guarantee long-lasting and trouble-free operation.

Features and application

The BBS-3/FL isolator is designed to work with a wide range of flat busbars with dimensions 12x5/10, 15x5/10, 20x5/10, 25x5/10 and 30x5/10. It has a snap-on slider that makes it easy to adapt to the specific busbar size, and internal screw holes provide stable and secure mounting. This makes the isolator suitable for both new installations and for expanding existing ones.

• Short-circuit protection: The isolator effectively protects the circuit from the effects of a short circuit, minimizing the risk of damage and fire.
• Temperature resistance: Withstands temperatures up to 120°C, making it suitable for use in harsh industrial environments.
• High quality materials: Made of thermoplastic without silicone and chlorine, ensuring durability and corrosion resistance.
• Safety confirmed by standards: Meets the requirements of IEC/EN 60439-1 and VDE 0660 Part 500 standards, guaranteeing compliance with applicable regulations.
• Universal mounting: Possibility of vertical or horizontal mounting increases installation flexibility.

Technical parameters and benefits for professionals

The BBS-3/FL isolator is characterized by a maximum rated current of 630 A and a busbar axis spacing of 60 mm. High resistance to creepage discharge (CTI 200) and self-extinguishing construction (UL 94) increase the safety level of the installation. This makes the isolator an ideal solution for demanding industrial and commercial applications. It provides easy access to circuits during service work, minimizing installation downtime. In addition, its design allows for the safe isolation of a section of the installation during measurements or repairs.
