Siemens Siemens 5SM27458 RCCB

Residual current operated circuit breaker, 2-pole, type AC, In: 40 A, 30 mA, Un AC: 230 V, with thermal overload protection The RCD is the residual current device for touch protection. The patented residual current protective devices from Siemens are an important component of the SENTRON protective devices for electrical installations, as they prevent life-threatening electrical accidents by safely disconnecting hazardous residual currents through grounding. Electrically ignited fires can be prevented as they occur. Whether the problem is direct contact with energized operating parts or indirect contact with equipment, protection is achieved primarily by rapid shutdown. The residual current operated circuit breakers are characterized primarily by: 1. Comprehensive protection from electric shock for personnel and property. 2. Whether sinusoidal residual alternating currents or smooth residual direct currents, Siemens provides the right type for all requirements and special versions 3. Be protected according...
