Terasaki E125 NJ 3 20 E125-NJ TemBreak2 circuit breaker 3P 20AFC

Rated working voltage: generally 400V, which is a common three-phase voltage level in industrial and commercial places, suitable for most three-phase electrical equipment and systems.

Rated insulation voltage: usually 690V, which can withstand higher voltages while ensuring good insulation performance, effectively preventing safety accidents such as leakage.

Rated impulse withstand voltage: for example, 8kV, which reflects the ability of the circuit breaker to withstand instantaneous high voltage shocks and can resist instantaneous overvoltages generated by lightning.

Short-circuit breaking capacity: The breaking capacity is an important indicator to measure the performance of the circuit breaker. This model may have a higher short-circuit breaking capacity, such as 50kA (effective value), which means that when the short-circuit current reaches 50kA, the circuit breaker can reliably cut off the circuit and protect downstream equipment and lines.

Use category: generally belongs to AC33B, suitable for motor circuits, and can provide reliable protection under different working conditions such as motor starting, operation and short circuit.
