It is designed for DC branch-circuit protection in control panels, switchgear, and distribution boards where a compact, DIN-rail-mount breaker is specified. The C16 trip curve means the breaker holds 1.13× to 1.45× rated current (18.1 A to 23.2 A) for over an hour, then trips magnetically between 5× and 10× In (80 A to 160 A). This suits motor-starting or moderate inrush loads where a B-curve would nuisance-trip but a D-curve would delay too long. The 2-pole configuration (2P) switches both the positive and negative conductors in a DC circuit, providing full isolation. This is standard for ungrounded DC systems or where double-pole disconnection is required by code. ## Deployment Context Snaps onto standard 35 mm DIN rail per EN 60715, fitting into a 36 mm-wide module (2 × 18 mm pole spacing). In a panel, account for the 10 kA SCCR when sizing the upstream bus and ensuring the enclosure short-circuit rating matches.","metaTitle":"Siemens 5SY5216-7CC12 MCB, 2P C16, 440V DC, 10kA","metaDescription":"Siemens 5SY5216-7CC12 miniature circuit breaker, 2-pole C16, 440V DC, 10kA breaking capacity.
