The E tripping characteristic is designed for applications requiring delayed overload response — typically feeder protection in residential and infrastructure panels where inrush currents from transformers or long cable runs need to ride through without nuisance tripping. The enclosure is rated IP40 with conductors connected, suitable for enclosed distribution boards. ## E-curve selectivity and coordination The E characteristic sits between the standard B/C curves and the selective S curve. The 690 V rated insulation voltage (Ui) and 6 kV surge voltage resistance confirm the part is built for main-panel duty, not just branch protection. Saddle terminals and box-terminal infeed are standard. The integrated locking slide accepts a padlock, wire seal, or cable tie for lockout/tagout. Depth is 76.3 mm, height 128 mm — check the gland plate clearance if the panel is shallow; the 3-module width is standard for a 2-pole main breaker on DIN rail. ## Environmental and mechanical ratings Shock resistance is 30 g for 11 ms duration, vibration resistance 2 g across 5–150 Hz per IEC 60068-2-6. Mechanical service life is 20,000 operating cycles typical. The switch position indicator shows green for OFF, red for ON — a quick visual check without opening the panel door.","metaTitle":"Siemens 5SP3216-3 SENTRON MCB, 2P E-Curve 400V 25kA","metaDescription":"Siemens 5SP3216-3 SENTRON miniature circuit breaker, 2-pole, E characteristic, 400V AC, 25kA breaking capacity.
