Description
Featuring a Type B tripping characteristic, the Hager NB316 is calibrated to trip magnetically between 3 and 5 times its rated current.
Key Features & Benefits
-
Simultaneous 3-Pole Isolation: Safeguards downstream three-phase machinery by disconnecting all three phases instantly during a fault, preventing dangerous single-phasing conditions.
-
Responsive Type B Curve: Calibrated for quick thermal-magnetic response on circuits without high inductive starting surges.
-
Standard 6kA Fault Rating: Provides reliable short-circuit protection for typical commercial, retail, and light industrial installations.
-
Hager Pull-Down Clip Design: Features Hager’s signature DIN-rail quick-release clip mechanism, making installation, removal, or retrofitting within busy panel boards incredibly fast and straightforward.
-
Unambiguous Visual Indication: Clear, front-facing mechanical flag indicators display the positive status of the internal contacts (ON/OFF) for safer maintenance workflows.
