| | Sponsored | | Our solenoid interlock door prevents access to temporary cable connections while the unit is energized, preventing access to connection points while the unit is under load. Access is allowed in the breaker section for monitoring, adjustments or service as needed via the secondary door. When the cables are de-energized, the lock is disengaged, and users can now safely remove or install their cables. |
