Type A detection means it catches pulsating DC fault currents up to 6 mA superimposed on the AC waveform — the minimum for circuits with single-phase rectified loads like washing machines, LED drivers, or EV chargers. The B-curve at 40 A trips between 3 and 5 times rated current (120–200 A magnetic release), sized for resistive or lightly inductive loads where inrush stays moderate — think lighting banks, small heaters, or control transformers.

Frequently asked questions
What is the 5SU1354-6KV40 used for?
It is a combined RCD/MCB (RCBO) for final subcircuits requiring both earth-fault and overcurrent protection in a single module — Type A residual current detection at 30 mA for personal protection, B-curve overcurrent trip at 40 A for resistive or low-inrush loads, with a 10 kA breaking capacity for distribution board use.
Where can I buy the 5SU1354-6KV40?
This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
