Gustav Hensel Geraete-Direktanschlussklemme 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.

Suitable for

• Industrial power distribution systems
• Building installation and sub-distribution boards
• Connection of large cross-section feeders to multiple branch circuits
