This Combi Resi9 SPU is a circuit breaker with built-in overvoltage protection. It is a 1P+N with 1 protected pole and the nominal current In is 40A.
Protects against atmospheric surges: flow of transient surges to ground, while ensuring continuity of service.
The associated C60 circuit breaker provides protection against continuous surges: overloads and short circuits.
This combined SPU unit is compatible with the TT grounding system.
It is mainly used in the residential and small tertiary sectors.
Type 2 surge suppressors are tested with an 8/20 s impulse current waveform.
The maximum discharge current of Imax is 15 kA. The nominal discharge current In is 5 kA.
The maximum continuous operating voltage Uc in differential mode (between phase and neutral) is 340VAC. The maximum continuous operating voltage of Uc in common mode is 260 VAC between neutral and ground.
The level of protection against voltage rise in differential mode (between phase and neutral) is less than or equal to 2.5 kV.
The High Voltage protection level in common mode is less than or equal to 1.5kV between neutral and ground.
Unrated service voltage is 230VAC. The operating frequency is 50Hz or 60Hz.
The dimensions are (W) 54mm x (H) 74mm x (D) 93mm.
The width in the 9mm lots is 6. The weight is 0.33 kg.
The protection degree is IP20 and IP40 in modular cabinets.
The operating temperature is -25°C to 55°C.
