EATON PFIM-40/4/003-G/F interruttore differenziale 40A 4 poli 30mA tipo F/G 187456

Residual current circuit breaker (RCCB) with surge current proof, short-time delayed tripping for frequency converter applications. The PFIM-40/4/003-G/F protects against residual currents of 30 mA in 4-pole networks up to 40 A, making it suitable for industrial and commercial power distribution where frequency converters or other equipment with high inrush currents are used.

Advantages

Type F/G characteristic ensures reliable operation even with mixed frequencies and smooth DC residual currents up to 10 mA. Surge current proof up to 3 kA prevents nuisance tripping. Short-time delay provides selectivity with downstream devices.

Suitable for

• Three-phase circuits with frequency converters
• Industrial control panels and machine power supplies
• Distribution boards requiring selective residual current protection
