Residual current circuit-breakers, four-pole, 63 A, 0,03 A, Type B NK, 290 V, 500 V, N left, HD

Residual current circuit-breakers (RCCB) switch the power supply off if dangerous high residual currents occur. DFS 4 are two-terminal or two-terminal pair residual current circuit-breakers for single- or three-phase networks. In the standard design, the compact devices are just four module widths wide. The compact residual current circuit-breakers are available with a number of different types of residual currents and versions at rated currents up to 125 A. The large two-tier terminals can also accommodate large conductor cross-sections. A practical multifunction switch toggle simplifies troubleshooting. They can be provided with pre-prepared labels using free-of-charge software. Type B switches are AC-DC sensitive. They protect against pulsating and AC residual currents, residual currents with mixed frequencies and smooth DC residual currents at frequencies up to 150 kHz. They have increased resistance to surge currents and bad weather conditions. For residual current circuit-breakers with characteristic curve NK, the tripping current frequency response runs below human tolerance levels for shock currents with different frequencies. For RCCBs with a rated residual current of 30 mA, extensive personal safety is achieved even with residual currents above the rated frequency. With an upper tripping threshold of 300 mA at frequencies up to 150 kHz, significantly more sensitive and wider-reaching protection from earth leakage currents is provided compared to characteristics B SK and B+. As a result, extensive fire protection is also possible even with electronic equipment with high clock frequencies. The wide scope of protection thanks to the NK characteristic requires the monitored system to be set up with low leakage currents. Devices in design V are made for special voltages. With an airtight, encapsulated tripping mechanism from a special alloy and the stainless steel latch, residual current circuit-breakers in HD design are protected, in particular from corrosion, corrosive gases, moisture and extreme temperature fluctuations.
