Description

Residual current circuit-breakers, four-pole, 80 A, 0,3 A, Type B+, N left

Function

Type B+ residual current circuit-breakers are AC-DC sensitive. They meet VDE fire protection requirements at 420 mA for frequencies up to 20 kHz. Standard RCCBs are designed for circuits with 230/400 V at 50 Hz.

Properties

AC/DC sensitive for residual currents with frequencies and mixed frequencies of 0 Hz (smooth direct current) up to 20 kHz, Fire protection as per VDE 0100-420, mains-voltage-independent tripping when type A residual currents occur, voltage-dependent detection of smooth DC and AC residual currents with frequencies not equal to 50 Hz, full functionality with mains voltages from at least 50 V AC on any two active conductors, compact design for all rated currents, high short-circuit resistance, double-sided two-tier terminals for large conductor cross-section and busbar, switch position indicator, viewing window for labels, multifunction switch toggle with three positions: "on", "off" and "tripped", Neutral conductor position left

Installation

quick fastening to mounting rail, any installation position, supply preferably from above

Applications

Commercial and industrial installations with TT, TN-S and TN-C-S systems, where power electronics equipment is used without galvanic isolation from the mains, e.g. frequency converters, switching power supplies, high-frequency converters, photovoltaic installations and UPS equipment with frequency converters without transformers, Facilities at risk of fire

Notes

suitable for use in 50 Hz AC networks, RCCBs for other frequencies available upon request, Not designed for use in direct current networks or on the output side of controlled electrical equipment such as frequency converters.
