The 1.6 A rating is at 35 °C ambient; derate it to 1.54 A at 40 °C, 1.5 A at 45 °C, and so on down to 1.4 A at 60 °C, so if your panel runs hot, size up accordingly. Width is 54 mm, which is 3 modular units (MW) on a standard DIN rail. Mounting position any, so you can orient it vertically or horizontally in a tight gland plate layout. Combined terminal top and bottom — that's a time-saver for the wireman: one screw captures both the incoming busbar and the outgoing conductor. Fastening method is the quick-assembly system (snap-on DIN rail), and it's sealable (padlockable handle) for lockout/tagout compliance.","metaTitle":"Siemens 5SY7315-7 SENTRON MCB, 3-Pole 1.6A C-Curve 15kA","metaDescription":"Siemens 5SY7315-7 SENTRON miniature circuit breaker, 3-pole, 1.6 A, C-curve.
