The interrupting capacity tells you where it can be installed safely: 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V. If your panel's fault current at 415 V is 100 kA, this breaker has headroom; if it's 130 kA, you need a higher-rated device upstream. The initial trip threshold is 16 A, meaning the thermal-magnetic element starts its characteristic bend at that level, not that the breaker holds 16 A steady. Full-scale trip is 63 A. Ground-fault monitoring is built in via summation current formation on L + N conductors, so it detects leakage without a separate module.
Deployment context
The 4-pole configuration suits three-phase-plus-neutral systems (TN-S, TN-C-S) where the neutral must be switched and protected. No communication function, no undervoltage release, no trip indicator: this is a basic thermal-magnetic breaker with ground-fault summation, specified for panels where remote monitoring and shunt-trip are not required.
The lifecycle stage is listed as current — meaning Siemens still manufactures this order code as an active catalog item. No end-of-life notice or last-time-buy date is on record.
