Surge Protector Apator ASA 500-10BO+D+K line bare set with disconnector (MPN 63-930218-071)

Apator ASA 500-10BO+D+K line bare set with disconnector is a surge protector kit designed for line-mounted installation in distribution networks. Supplied as a complete unit, this device provides protection against transient overvoltages and is intended to be installed on overhead lines where a compact, integrated arrestor with automatic disconnection function is required. The unit is suitable for protecting transformers, distribution lines and connected equipment from impulse and switching surges.

Advantages

The ASA 500-10BO+D+K combines overvoltage protection and an integrated disconnection mechanism in a single line-mounted assembly, reducing the need for additional components and simplifying installation. Its design supports reliable operation in distribution environments and helps limit stress on downstream equipment by diverting surge energy to ground while the disconnector isolates a failed element to prevent sustained leakage or damage. The kit format ensures consistent compatibility between the arrestor and the disconnector for safer, faster commissioning.

Suitable for

• Protection of medium-voltage distribution lines and overhead feeders
• Safeguarding distribution transformers and pole-mounted equipment
• Line-mounted installations where disconnection after surge fault is required
• Retrofit applications on existing overhead networks to improve surge resilience

Key specifications

• Type: Line-mounted surge arrester with integrated disconnector
• Form: Bare set intended for overhead line assembly
• Application: Protection against transient overvoltages (impulse and switching)
• Installation: Designed for outdoor use on distribution network lines
• Functionality: Automatic disconnection of the arrestor on end-of-life or failure

How to use

Install the ASA 500-10BO+D+K on the overhead line at the designated protection point in accordance with local electrical codes and utility practices. Mount the bare set on the conductor and secure the mechanical connections as specified by the installation manual. Ensure proper earthing of the system so that diverted surge energy is safely conducted to ground. After installation, verify continuity, mechanical fastening and earthing before energizing the circuit. If the disconnector operates following a surge event, replace the unit according to the service procedures to restore full protection.

Usage recommendations

Use this surge protector as part of a coordinated overvoltage protection scheme. Verify compatibility with system voltage levels and earthing arrangements before installation. Periodic visual inspection and functional testing after severe events are recommended to ensure continued protection performance.
