The Siemens 5SU1353-1KV16 is a combined residual-current and miniature circuit breaker (RCBO) — an FI/LS protector of Type AC (wave shape), rated at 30 mA sensitivity, 4.5 kA breaking capacity, 1+N poles, C characteristic, 16 A. This is the unit that sits on a DIN rail in a distribution board, protecting a single-phase final subcircuit against both overload/short-circuit and earth-fault currents. The Type AC designation means it detects sinusoidal AC residual currents only — standard for general-purpose socket circuits, lighting, and small loads where no pulsed DC or smooth DC fault currents are expected.

Frequently asked questions
Where can I buy 5SU1353-1KV16 and get current pricing?
Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
What does Type AC and 30 mA sensitivity mean for this RCBO?
Type AC detects sinusoidal AC residual currents only — standard for general-purpose socket and lighting circuits. 30 mA sensitivity provides personal protection against direct-contact earth faults.
