Product Introduction
KINEE KNID-100L RCCB (Residual Current Circuit Breaker, also known as leakage circuit breaker or residual current device) is a key protective device in low-voltage distribution systems, designed to provide protection against electric shock and fire hazards caused by earth leakage currents. As a 6kA Breaking Capacity RCCB, it ensures reliable short-circuit withstand capability in demanding installations.
This series offers AC, A, S and B types, with rated current from 16A to 125A, available in 2P(1P+N) and 4P(3P+N) versions to meet both single-phase and three-phase applications. The 6kA Breaking Capacity RCCB design enhances system safety by limiting the let-through energy during fault conditions.
Selectable residual operating currents of 10mA, 30mA, 100mA, and 300mA ensure reliable protection for personnel safety and equipment security. With its 6kA Breaking Capacity RCCB performance, the KNID-100L is suitable for a wide range of industrial and commercial distribution boards.
For superior protection and durability, choose this 6kA Breaking Capacity RCCB to safeguard both people and property against earth leakage and short-circuit risks.
The KNID-100L electromagnetic residual current operated switch has the following functions:
· Supplementary personal protection against direct contact (≤ 30 mA)
· Personal protection against indirect contact (≥ 100 mA)
· Protection against insulation faults in electrical equipment, such as prevention of electrical fires (300 mA)
·Top-in bottom-out or bottom-in top-out wiring configuration
