Why Choose the Mersen BNIT55V16M20 Busbar Support Insulator?

The Mersen BNIT55V16M20 is a robust electrical busbar support insulator designed to provide dependable mechanical support and electrical separation within switchgear, distribution panels and industrial power systems. Manufactured by Mersen, it is suitable for professional panel builders, electrical engineers and equipment manufacturers requiring a secure method of mounting conductive busbars.

This support insulator helps maintain the required distance between energised conductors and surrounding metalwork. Its rigid construction stabilises busbar assemblies against movement and mechanical stress, helping improve the safety, reliability and service life of electrical installations.

The BNIT55V16M20 features a compact cylindrical format with an M20 threaded mounting connection, allowing it to be securely incorporated into compatible electrical enclosures and busbar structures. Its durable insulating body makes it well suited to demanding industrial environments where dependable electrical insulation and mechanical strength are essential.
