JC3BE-DC DC circuit breaker
TECHNICAL DATA
JC3BE-DC DC circuit breaker specifications
The JC3BE-DC DC circuit breaker is listed for photovoltaic, energy-storage and other direct-current circuits. Its target-page table specifies pole-dependent DC voltages and a breaking rating; select the complete pole and current configuration rather than applying the highest voltage to every version.

SELECTION GUIDE
JC3BE-DC photovoltaic DC MCB selection
Specify the complete order code, circuit duty, installation conditions and required documents when requesting a JC3BE-DC quotation from W9 Group.
Define the supply circuit
Provide the supply type, maximum circuit voltage and earthing arrangement. Confirm the required pole connection from the matching wiring diagram.
Coordinate current and release
Choose the ordered current using conductor and load duty. Request the exact trip curve and any installation-related derating.
Compare fault interruption
Provide the prospective short-circuit current. Confirm the breaking rating, operating voltage and applicable test standard together.
Check installation details
Request terminal limits, mounting dimensions, torque and accessory compatibility for the complete model code.

BUYER FAQ
JC3BE-DC DC circuit protection FAQs
Find answers about JC3BE-DC selection, configuration and ordering.
What is the DC voltage rating for each pole configuration?
The original table lists 1P at DC250V, 2P at DC500V, 3P at DC750V and 4P at DC1000V. Confirm the required pole wiring and system arrangement for the ordered version.
Which current options and trip curves are listed?
The table lists 2, 4, 6, 10, 16, 20, 25, 32, 40, 50 and 63 A, with B and D characteristics. Confirm the selected current and exact time-current curve.
What does the 10kA rating apply to?
The target table lists 10kA and IEC/EN60947-2. Confirm the operating voltage, pole configuration and fault test conditions for the offered unit.
Can I reverse the supply connection?
The supplier describes non-polarity and bidirectional operation. Confirm the exact terminal diagram and permitted supply connections for the selected version before wiring.
Does this DC MCB replace residual-current protection?
It provides overload and short-circuit protection. Confirm the separate residual-current, insulation-monitoring and earth-fault measures required by the system design.
How is the breaker mounted?
The original table lists mounting on 35mm DIN rail. Confirm enclosure clearances, terminal conductor limits and tightening instructions for the actual installation.
What is needed for a JC3BE-DC quotation?
Send the required configuration, quantity, destination market and document requirements. Ask W9 Group to confirm price, minimum order quantity, samples and lead time for the selected configuration.
