The Siemens 5SL5813-7 is a 2-pole miniature circuit breaker rated 13 A with a C-trip curve, interrupting 6 kA at 110 V DC. It fits a single modular width of 18 mm on the DIN rail, so it occupies one slot in a standard distribution board or control panel.
The 18 mm width (1 MW) matches standard modular enclosure cutouts. Terminals accept copper conductors up to the cross-section typical for a 13 A branch circuit; strip length and torque values follow the Siemens installation instructions printed on the side of the breaker. The 2-pole configuration switches both the positive and negative legs on a 110 V DC system — required for DC circuits where the return path is not grounded, or where full isolation is needed for maintenance.
