Siemens 5SY4214-8CV, miniature circuit breaker, 2-pole, D-characteristic 0.3 A, breaking capacity Icu=15 kA at 400 VAC.
The 2-pole configuration switches both phase conductors simultaneously, which is standard for single-phase 230 V loads in a 400/230 V TN system or for two-phase motor control circuits where simultaneous disconnection is required by local wiring rules.
Alternative models and sibling configurations in the same Siemens series. For obsolete or discontinued parts, these models can serve as compatible replacements or functional alternatives for plant maintenance.
