Borne de conexión directa de aparatos Gustav Hensel DA 300

Direct connection terminal for safe and efficient distribution of electrical power in industrial and building installations. The DA300 handles main conductors up to 300 mm² and branches up to 50 mm², supporting rated currents up to 500 A. Its robust construction and finger-safe design ensure reliable performance in demanding environments.

Advantages

With a rated impulse withstand voltage of 8 kV and short-circuit withstand current of 25 kA, the DA300 provides excellent electrical safety. The polyamide housing is flame-retardant (UL 94 V-0) and offers IP20 protection, making it suitable for use in control cabinets and distribution boards. The terminal accommodates both copper and aluminium conductors, and its screw connection technology ensures a secure and maintenance-free contact.
