Operation Guide


1. Installation

  - Mount vertically on panels with fixed contacts (power source) above and moving contacts (load) below. Horizontal mounting prohibited.

  - Busbar torque: 80N·m for 1000A models (use lock washers).


2. Operation

  - Close: Grip handle and push steadily to ON until full blade engagement.

  - Open: De-energize load first, then swiftly pull handle to OFF to enhance arc extinction via airflow.
