The short-time delayed design (designated as short-time delayed in the product designation) means it tolerates brief surge currents without nuisance tripping — useful on circuits with capacitive inrush or where selectivity with downstream RCCBs is required. The 30 mA trip level covers standard personnel protection (hand-to-hand or hand-to-ground fault paths). Type A detection handles pulsating DC residual currents from rectifiers or switched-mode supplies, so this RCCB is a fit for mixed-load panels feeding electronics, VFDs, or LED drivers alongside resistive and motor circuits. The short-circuit current rating (SCCR) is 10 kA per IEC 61008-1 and EN 60898 (0.8 kA at the respective standard ratings). Overvoltage category III means it's rated for fixed-installation distribution boards, not just downstream socket outlets. Surge current withstand is 3 kA (8/20 µs waveform), and the permissible I²t let-through is 58,000 A²·s — both figures tell you the device holds in on transient events without welding contacts or degrading the trip mechanism. The supply connection is accepted from top or bottom, and mounting orientation is any position, which simplifies panel layout. DIN-rail mount (REG profile) — clips on without tools. Depth is 70 mm, width 72 mm (4 MW), height 90 mm. Silicon-free construction is noted for applications sensitive to silicone outgassing (e.g., certain coating or potting processes). The test circuit requires a minimum of 195 V to operate the test button — verify line-to-neutral or line-to-line voltage on the supply side meets that threshold for periodic testing. The RCCB is designed with thermal overload protection integrated (product variation), meaning it also provides overcurrent protection up to its rated breaking capacity, not just residual current detection.","metaTitle":"Siemens SENTRON 5SV3344-6LA01 RCCB, 4P, 40A, 30mA, Type A, 1","metaDescription":"Siemens SENTRON 5SV3344-6LA01 4-pole RCCB, 40 A rated, 30 mA residual, Type A, short-time delayed. 10 kA SCCR.
