The DC voltage rating of 440 V maximum is the headline figure: this breaker is built for DC-side protection, not AC mains. The 2-pole design switches both lines in a DC circuit, which is required for full isolation on ungrounded or bipolar DC systems. The C characteristic governs the magnetic trip threshold. For a 20 A breaker, the instantaneous trip activates between 100 A and 200 A. This makes it appropriate for circuits where the connected load has a brief startup surge that would nuisance-trip a B-curve device, but not the sustained overloads that call for a D-curve. The 5SL5220-7RC occupies 2 modular width units (36 mm) on a DIN rail, with a depth of 76 mm and an installation depth of 70 mm. The 90 mm height is standard for SENTRON MCBs. Supplementary devices such as auxiliary switches, shunt trips, or undervoltage releases can be installed, allowing remote status monitoring or emergency trip integration. The breaker is sealable, which supports tamper-proofing for metering or tenant sub-circuits. The degree of pollution is rated 2, and the overvoltage category is III, per IEC 60947-2. These ratings define the creepage and clearance distances for reliable operation in fixed installations. The product brand is SENTRON, Siemens' standard line for distribution protection.","metaTitle":"Siemens 5SL5220-7RC SENTRON MCB, 2P C 20 A DC 440 V","metaDescription":"Siemens SENTRON 5SL5220-7RC miniature circuit breaker, 2-pole, C-curve, 20 A, DC 440 V, 10 kA.
