The 1-pole design means it switches only the phase — neutral is not broken inside the device, so the panel builder must provide a separate neutral bar. Installation depth is 70 mm into the enclosure; overall depth 76 mm. The 18 mm width (one modular unit) packs tightly on a DIN rail — useful when backpan density is a constraint. ## Deployment context — where this lives in a panel Sealable (padlockable toggle) allows lockout/tagout on the circuit without removing the breaker. The -40 °C to 75 °C operating range covers unheated service entrances and enclosures near process heat; the 75 °C upper limit is the breaker's internal temperature rise plus ambient, not a surface-touch rating.","metaTitle":"Siemens 5SL4104-7RC SENTRON MCB, 1P C 4A 10kA","metaDescription":"Siemens 5SL4104-7RC SENTRON miniature circuit breaker, 1-pole, C-curve, 4 A, 10 kA breaking capacity per EN 60898.
