Product Description

Miniature  circuit breakers are suitable for AC 50Hz, rated voltage 230V/400V, and rated current up to 63A lines. Mainly used for overload and short circuit protection of lighting, distribution lines, and equipment in office buildings, residential buildings, and similar buildings. It can also be used for infrequent line switching under normal circumstances.

The circuit breaker has beautiful appearance, advanced structure, reliable performance, high breaking capacity (10kA), short flashover and other characteristics; It is an ideal product for industrial, commercial, high-rise, and residential customers.

Technical parameters:
Number of poles: 1p, 1P+N, 2p, 3p, 3P+N, 4p
Rated voltage: 230/400 V
Rated frequency: 50/60 Hz
Rated short-circuit breaking capacity: 10kA
Electrical life: at Un, In, and COS=0.90, 63A and below: 8000 cycles; 80A -100A: 1500 cycles (each cycle includes one making operation and one breaking operation)
Mechanical life: 63 A and below: 20000 cycles; 80A~100A: 10000 cycles
Withstand voltage: power frequency withstand voltage 2000V (1min), pulse withstand voltage 6000V (1.2/50 μ S)
Impact resistance: withstand at least 18 impacts of 10ms and 20g; Withstand at least 18 impacts of 5ms and 40g; Anti vibration performance: withstand 3g at 10~55Hz and vibrate for at least 30 minutes. Storage temperature: According to IEC88 Part 2 Section 1 (lasting for 96 hours) -55 ºC~+55 ºC
Working environment temperature: -5 ºC~+40 ºC
Protection level: IP40 (after installation)
Wiring capacity: 63 A and below: 25mm flexible wire ³ And below, hard wire 35mm ³ And below; 80A~100A: flexible cable 35mm ³ Up to and including, hard wire 50mm ³ And below.
DC application: 1A~63A: rated short-circuit breaking capacity: 6kA; Maximum voltage: single pole 60V; Bipolar series connection 110V; 80A~125A: Rated short-circuit breaking capacity: 10kA; Maximum voltage: bipolar series connection 125V; Quadrupole series connection 250V; The instantaneous tripping current is about 40% higher than when used for AC 50/60Hz.

Technical characteristics:
Compliant with standard: 63A and below: IEC60898 GB10963
80-100A: IEC947-2 GB14048.2
Modular design: Each width of 18mm (63A shell rating) or 27mm (125A shell rating) can be selected for rated current according to temperature adjustment curves at different ambient temperatures.
Free release mechanism: In case of short circuit or overload, the circuit breaker automatically releases. Even if the handle is pushed to the closed position before the fault is cleared, the circuit cannot be reconnected
To avoid Human error to connect the fault circuit.
Instantaneous tripping characteristic: B characteristic: 3~5In; C characteristic: 5-10In; D characteristic: 10-20In.

The appearance and installation dimensions adopt IEC standard DIN Rail 35mm
