The Siemens 5SU1153-0KV16 is a combined residual current device and miniature circuit breaker (RCBO) in a single DIN-rail module — Type AC detection, 10 mA trip sensitivity, B-curve 16 A overcurrent protection, rated breaking capacity 4.5 kA. The 10 mA sensitivity is the key spec here: that's the threshold for personal protection against direct contact (below the IEC 60479 ventricular fibrillation threshold), so this unit is sized for circuits where even a small leakage to ground needs to clear fast — think wet locations, portable equipment, or medical-grade sockets in non-critical areas. The B-curve (3-5x In magnetic trip) means it's suited for resistive or lightly inductive loads, not motor starting inrush.

Frequently asked questions
Where can I buy 5SU1153-0KV16 and get a price?
Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time on your required quantity.
What is the breaking capacity of 5SU1153-0KV16?
Rated breaking capacity is 4.5 kA, which is the standard short-circuit rating for Siemens 5SU1 series RCBOs in domestic and commercial distribution boards. Verify that the prospective short-circuit current at the installation point does not exceed this value.
