The short-time delay (SIGRES function) allows selectivity with downstream RCCBs: the upstream delayed unit holds during a downstream fault, so only the faulted branch opens. Snap-on DIN rail (REG) mounting, any orientation. Supply can be connected top or bottom; the SIGRES function (short-time delay) remains active even when the switch is in the off state, so the test circuit stays powered from the top terminals. Grid spacing 60 mm aligns with standard modular panel layouts. Silicon-free construction matters for automotive or aerospace panels where silicone outgassing can contaminate contacts or optics.","metaTitle":"Siemens SENTRON 5SV3344-4KK14 RCCB, 40A, 30mA, Type B+, 4-po","metaDescription":"Siemens SENTRON 5SV3344-4KK14 RCCB, 4-pole, Type B+, short-time delayed, 40A, 30mA, 400V AC, 10kA SCCR.
