It integrates Type AC residual-current detection (30 mA trip threshold) with a B-curve overcurrent characteristic rated at 10 A, all within a single 70 mm wide module. In a domestic or light commercial distribution board, this covers the majority of installations where the upstream short-circuit capacity does not exceed 10 kA. The B-curve (10 A) trips between 3 and 5 times rated current (30–50 A) for fast disconnection of resistive and small inductive loads. The 1+N-pole configuration switches the line conductor and provides a switched neutral — the neutral pole opens and closes with the line, which is required in some regional wiring rules (e.g., UK, Australia) to ensure isolation on both poles when the device trips. ## Deployment context The 70 mm width (4 module spaces on a standard DIN rail) fits into residential or commercial distribution boards alongside other Siemens 5SU-series RCBOs and MCBs.","metaTitle":"Siemens 5SU1354-0KV10 FI/LS Protector, Type AC, 30mA, 10kA,","metaDescription":"Siemens 5SU1354-0KV10 FI/LS protector, Type AC, 30mA trip, 10kA breaking capacity, 1+N-pole, B-curve 10A.
