Doepke 09114861 RCCB B

Ground fault circuit interrupter (RCCB) switch off the power supply in case of dangerously high fault currents. Thus, you protect persons, animals and plants. DFS 4 are two or four pole ground fault circuit breakers for single or three phase networks. In standard design, the compact devices are four division units narrow. They are available with many different fault current types and versions at rated currents up to 125 A. The large double level terminals can also accommodate large conductor cross-sections. The trip position of the multifunction toggle facilitates troubleshooting. The free label software helps with the labeling. Type B switches are all-current sensitive for frequencies from 0 Hz (smooth DC fault currents) to 150 kHz. They are surge current and weatherproof. Error current circuit breakers of the SK series stand for fault current protection and a high plant availability. They are characterized by lower sensitivity at higher frequencies. The characteristic SK is optimized for systems where no fire protection is required. Buttons for switching off in emergency situations, for example, can be connected to a NA-type fault-current circuit-breaker. An integrated LED indicates the emergency triggering through buttons or broken wires. The ground fault circuit breaker can only be switched on again after correction. Several RCCCBs can be connected in parallel. Properties: High immunity to operational leakage and fault currents at frequencies above 1 kHz; all current sensitive for fault currents with frequencies and mixed frequencies from 0 Hz (smooth DC) to 150 kHz; mains voltage independent triggering in case of fault currents of type A; voltage-dependent detection of smooth DC fault current and alternating fault currents with frequencies not equal to 50/60 Hz; Full functionality with line voltages from at least 50 V AC on any two active conductors; with EMERGENCY STOP function for triggering or Switching by means of actuating elements; monitoring of the EMERGENCY STOP function on wire break and display by an LED; small size for all rated currents; high short-circuit resistance; double-sided double-level terminals for large conductor cross-section and rail connection; switch position display; sight window for label labels; multi-function switching lever with three positions: "ON", "OFF", "triggered"; connection C1 neutral conductor position left; mounting type: Mounting on mounting rail; mounting any; mounting position; Supply from above; application areas: commercial and industrial installations with TN-S, TT and TN-C-S systems in which power electronics equipment without galvanic isolation is used, such as frequency converters, switched-mode power supplies, high-frequency converters, photovoltaic and UPS systems with transformerless inverters; RCCB of the NA series are particularly suitable for plants in which an EMERGENCY-OFF circuit with isolator characteristics is to be provided. Such as classrooms or production facilities; notes: Suitable for use in 50-Hz AC networks; RCCB for other frequencies on request; not intended for use in DC power systems and on the output side of controlled electrical equipment such as frequency converters.
