It's rated 16 A with a Type C tripping characteristic and Type A fault-current sensitivity, making it a go-to choice for final circuits in commercial and residential distribution boards where both short-circuit and earth-fault protection are needed on a single DIN-rail footprint. The 16 A rating at 30 °C is the headline number, but the derating curve tells the real story for a warm enclosure: at 40 °C it's 15.04 A, at 45 °C it's 14.56 A, and at 55 °C it drops to 12.96 A. The EN figure governs domestic and light commercial boards; the IEC figure applies when the device is specified per the industrial standard. Either way, it's rated for the fault levels typical of a sub-distribution board fed from a transformer of up to about 630 kVA. The energy limiting class of 3 means it lets through less let-through energy (I²t) than class 1 or 2 devices — helpful for downstream cable protection. Type A residual-current detection covers sinusoidal AC faults plus pulsating DC faults up to 6 mA smooth DC — the standard for circuits with electronics, rectifiers, or single-phase drives. The instantaneous design (no intentional delay) trips within 40 ms at rated residual current, which is the norm for socket-outlet circuits where personnel protection is the goal. Supply can enter from either top or bottom — no mandatory orientation. The terminals accept solid or stranded conductors from 0.75 mm² up to 35 mm², which covers everything from 1.5 mm² lighting circuits to 10 mm² submains. Touch protection is built in (fingertip-safe terminals per the standard). Mounting position is any — horizontal, vertical, flat — no derating required for orientation.","metaTitle":"Siemens 5SU9356-7KP16 SENTRON RCBO, 16A Type A, 6kA/10kA","metaDescription":"Siemens 5SU9356-7KP16 SENTRON RCBO, 16A rated, Type A, 30mA, 6kA EN/10kA IEC, 1P+N, 2-module.
