The Siemens 5SU1354-0LV32 is a combined residual current device and miniature circuit breaker — an RCBO — in a single 1+N-pole module. The Type AC (WS) designation means it detects sinusoidal AC earth faults only, with a rated residual operating current (IΔn) of 30 mA, the standard for personal protection against direct contact. The B-curve MCB side trips at 5-10x rated current, protecting 32 A final circuits against short-circuit and overload. Breaking capacity is 10 kA, sufficient for most residential and light commercial distribution boards where the prospective fault current at the point of installation is known to be below that level.

Product details
Frequently asked questions
What do the ratings on the 5SU1354-0LV32 mean for installation?
30 mA IΔn provides personal protection against direct contact. The B-curve (5-10x In) is sized for resistive or short cable runs where inrush is low. 10 kA breaking capacity handles typical domestic fault levels. The Type AC detection means it is suitable for sinusoidal AC residual currents only — not for pulsed DC or mixed-frequency faults found on variable-speed drives or EV chargers.
Where can I buy the 5SU1354-0LV32?
Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing confirmed at quote time.
