Release curve

The M5 electronic circuit breaker provides multiple trip curves for system coordination and design.

1. Long delay trip curve (Li/Lsi/Lsig)

Display the inverse time characteristic of overload protection (L)

Tr adjustable range: 3s to 30s (7-speed)

Curve varies with Ir and Tr settings

2. Short delay trip curve

Display the delay characteristics of short-circuit protection (S)

Tsd adjustable range: 0 to 500 ms

Optional I ² t=K or t=K characteristics

3. Instantaneous release curve

Fixed instantaneous trip value: 15kA (500-1250A)/20kA (1600A)

Ensure rapid response to extremely high short-circuit currents

4. Through the energy curve (I ² t)

Display the allowable conduction energy under different expected short-circuit currents

A lower I ² t value means better protection for downstream equipment

5. Peak current cut-off curve

Display the peak current that the circuit breaker can limit in the event of a short circuit fault

Intuitively reflect the current limiting performance of circuit breakers

Application scenarios and selection suggestions

1. Typical applications

Main incoming distribution: main incoming cabinets for factories, commercial buildings, and data centers

Large scale power distribution: Distribution circuits for large equipment

Generator protection: Generator set outlet protection

Transformer protection: Main protection on the low voltage side of the transformer

ATS system: main switch in the automatic switching system of main and backup power supply

2. Key selection points

Rated current: Choose specifications from 500A to 1600A based on the load current

Breaking capacity: Select F/N/H/L level based on system short-circuit current

Protection type: Choose Li, Lsi or Lsig, do you need ground fault protection

Measurement requirement: Is it necessary to integrate power measurement function

Communication requirements: Do you need MODBUS communication and remote monitoring

Installation method: fixed or pull-out

Attachment requirements: auxiliary contacts, shunt release, electric operation, rotating handle, interlock, etc

Environmental conditions: Temperature, altitude, humidity need to be considered for capacity reduction
