Dongfa Intelligent supplies factory-direct DC 220V 98 Ohm Closing and Tripping Coil for high voltage vacuum circuit breaker operating mechanisms. The coil operates at DC220V with 98Ω ±5% resistance, approximately 2.24A steady-state current, and approximately 493W instantaneous power under short-time duty conditions. It features plug-in terminals, external reset spring, brass push rod with locking nut, white flame-retardant bobbin, and top 5-hole mounting structure.
The 98Ω coil provides higher current output than conventional higher resistance coils. At DC220V, the steady-state current is approximately 2.24A and instantaneous power is approximately 493W, providing stronger electromagnetic driving force for vacuum circuit breaker operating mechanisms with higher mechanical resistance.
The plug-in terminal design allows direct connection with matching receptacles without additional soldering or crimping, improving assembly efficiency and simplifying replacement maintenance.
The external reset spring allows easier inspection and replacement. The brass push rod with locking nut supports position adjustment to match different operating mechanism requirements.
The top threaded 5-hole structure provides more installation options for different vacuum circuit breaker mechanisms and helps improve mounting compatibility.

Compared with a 131.5Ω coil, the 98Ω design provides higher current and stronger electromagnetic output. It is suitable for operating mechanisms requiring stronger action force or faster response.
This coil is designed for short-time energization. The control circuit should reliably disconnect power after operation to avoid overheating caused by long-term energization.
For replacement projects, please provide original coil model, operating voltage, resistance value, mounting dimensions, push rod stroke, and quantity for compatibility confirmation.
