1
Four-chamber independent flameproof design: after tripping, the main chamber is de-energized, allowing maintenance without disconnecting the upstream power supply.
2
Multi-user interlocking system: four-position redundant lockout points, preventing closing operation until all locks are released by personnel.
3
Dual-drive redundancy: permanent magnet mechanism as the primary drive, with mechanical manual backup to ensure reliable switching even under power loss conditions.
4
Status visualization: transparent arc cover with backlight for clear contact position indication; reserved interfaces for temperature measurement and infrared expansion.
5
Quick-opening structure: external latch + internal locking mechanism, tool-free fast opening, enabling single-person operation in about 10 seconds.
6
Intelligent connectivity: unified isolated RS485/RJ45 interfaces on both high and low voltage sides, directly connected to monitoring platforms, supporting remote operation and maintenance.
