Hubbell Introduces the LineDefender Advanced Lateral-Protection Recloser to Enhance Grid Reliability and Worker Safety

SHELTON, CONN. – MARCH 24, 2025 – Hubbell Incorporated today announced the release of the LineDefender™ advanced lateral-protection recloser that helps significantly reduce sustained power outages, while setting a new standard for both line worker safety and operational efficiency.

The recloser automatically detects and clears temporary faults, restoring power without crew deployment. When permanent faults occur, the device de-energizes the circuit and provides clear, visible indication through a semaphore and a flashing beacon, facilitating swift fault identification and restoration. After the fault source is cleared, the LineDefender recloser enables crews to safely restore power from the ground by toggling an easy-to-access yellow handle.

“The LineDefender recloser represents a breakthrough in grid reliability and workplace safety,” said Erik Christian, division president, grid automation for Hubbell. “By combining sophisticated fault management with groundbreaking safety features, we’re helping utilities minimize outage impacts while protecting their most valuable assets – their workers.”

Revolutionary safety features

• The lateral-protection recloser offers operating handles and visual indicators that are familiar to line workers within a fused cutout that attaches to a single point mount bracket.
• Line workers can easily restore power from the ground by operating a yellow handle with a hot stick while the device stays securely latched in its original position.
• Secure latching of the device within the power fuse cutout prevents accidental dropout while also allowing for visible air-break that offer assurance of safe working conditions.
• A singular hot line trip mode feature provides best-in-class clearing time under lightly loaded or low fault current conditions for enhanced line worker safety.

Streamlined operations

• The recloser is a cost-effective solution because it is compatible with common overhead line construction envelopes and mountings and requires minimal maintenance.
• Visible indicators that are clear in most weather and lighting conditions provide faster fault identification.
• Balanced weight distribution and guided alignment allow line workers greater flexibility and safety when creating or closing visible air-breaks.
• Ease of connectivity with integrated local Wi-Fi/Bluetooth pairing and “plug-on” cellular SCADA module enhances communications.

The LineDefender recloser works with the GridHUBB™ software platform, which enables utilities to configure, manage and control Hubbell intelligent grid devices through an intuitive user interface. GridHUBB software is compatible with Windows, iOS and Android platforms and provides advanced programming and reporting tools. Additionally, the software has embedded help and support features that enable easy training of utility personnel.
