The Type A detection covers sinusoidal AC and pulsating DC residual currents, which is the standard requirement for most commercial and industrial final circuits with electronic loads. Snap-on DIN rail (REG) mounting, any position. Spring-cage terminals accept top or bottom feed — no polarity concern on the line/load side for an RCCB. Lifecycle stage is current.","metaTitle":"Siemens 5SM3648-6 SENTRON RCCB, 4P, 100 A, 300 mA, 400 V AC","metaDescription":"Siemens SENTRON 5SM3648-6 RCCB, 4-pole Type A instantaneous, 100 A rated, 300 mA sensitivity, 400 V AC, 10 kA SCCR.
