Circuit Breaker — Carling Technologies 1-Pole 100A — Delay 03 (Hydraulic-Magnetic — Switch-Only)
1-Pole • C-Series • Delay “03” = Switch-Only (no protective trip) • Tested Reclaimed Part

Genuine Carling C-Series unit built with Delay Code “03”. Delay 03 is a switch-only configuration (no hydraulic-magnetic trip element). It provides panel ON/OFF switching in the C-Series form factor and should not be used where overcurrent protection is required.

Where it’s used (typical)
  • Non-protective power switching / service disconnect
  • Maintenance bypass / test benches / control power switching
  • Applications using external fusing or upstream protection
