Description

Residual current circuit-breakers, four-pole, 40 A, 0,03 A, Type B NK, 290 V, 500 V, N left

Function

Type B residual current circuit-breakers are AC-DC sensitive. The NK characteristic provides classic fire protection at 300 mA for frequencies ranging from 0 to 150 kHz. Our NK circuit-breakers are ideally suited for the reliable protection of locations where a particular risk of fire exists. Our V RCCBs are designed for special voltages – ensuring optimal protection for your specific applications.

Properties

AC/DC sensitive for residual currents with frequencies and mixed frequencies of 0 Hz (smooth direct current) up to 150 kHz, high availability even of voltage-independent detection of smooth DC residual current and AC residual current with frequencies not equal to 50/60 Hz thanks to full functional compatibility with mains voltages from at least 50 V AC on any two active conductors, mains-voltage-independent tripping when type A residual currents occur , 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

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.
