Product Detail

MCB, RCBO & RCCB: • 10/15kA Miniature Circuit breakers in B,C and D Type up to 63A • 125A High current Miniature Circuit breaker in 3-pole C Type • Wide range of accessories available for K Series MCBs including; shunt trip, dolly locks and auxiliary switches. • 10kA Double module SP&SwN RCBOs up to 40A / 30mA • 10kA Single-module RCBOs up to 45A / 30mA and 40A / 100mA • RCCBs available in 2-pole and 4-pole versions with 100A / 100mA Time delay version The main parameter of a residual current device is rated residual operating current IΔn . Normalized values are 10, 30, 100, 300, 500 mA and 1 A. If the residual current achieves the value of 100 % IΔn or more, the RCD must trip. If the residual current does not reach 50 % IΔn , it must not trip. Thus, the RCD can trip from 50 to 100 % IΔn . This practically means that, given a sensitivity of RCD of 30 mA, tripping may occur as early as once the earth- -leakage current of 15 mA is achieved, which causes problems in installations with higher leaking currents. This increases their applicability in circuits with higher leaking currents. Protection of RCCB against contact overloading Correctly executed protection of contacts from surge currents means that constantly passing current will not exceed the value of their rated current, for which they are designed.
