It mounts on a 40 mm busbar system per DIN 43870 Part 2, common in meter-panel installations, and occupies 1.5 width units. The enclosure measures 89.5 mm deep by 151.3 mm high, and the part carries an IP40 rating with connected conductors — suitable for dry indoor enclosures, not washdown environments. With a shock resistance of 30 g and vibration resistance of 2 g per IEC 60068-2-6, it's mechanically robust enough for transport and normal panel vibration. ## Tripping characteristic E and coordination Tripping characteristic E is a less common curve than the standard B, C, or D. It's designed for circuits with moderate inrush — think transformer primaries or groups of LED drivers — where a C curve might nuisance-trip but a D curve delays too long for conductor protection. The E curve sits between C and D in magnetic trip threshold, typically 8–12× In. For the 16 A rating, that means the magnetic trip fires between roughly 128 A and 192 A. This matters for selectivity: you need to verify the upstream breaker's let-through does not exceed the 25 kA rating of this device. ## Integration notes Mounting is via a 40 mm busbar system — not a standard DIN rail. The outgoing feeder uses a spring-loaded terminal, which speeds wiring compared to screw terminals. The part is sealable, with a locking slide accepting a padlock, wire seal, cable ties, or Antilux. The switch position indicator shows OFF = green, ON = red. Infeed is stipulated at the lower section of the meter panel via box terminal. Mechanical service life is 20 000 switching cycles.","metaTitle":"Siemens SENTRON 5SP3716-2KK03 Miniature Circuit Breaker, 1P,","metaDescription":"Siemens SENTRON 5SP3716-2KK03 1-pole miniature circuit breaker, 16 A, tripping characteristic E, 25 kA breaking capacity per EN 60898.
