Frequently Asked Questions (FAQ)

What is the primary function of the SJK47LE-63 series circuit breaker?
The SJK47LE-63 is a residual current circuit breaker with overcurrent protection (RCBO). It provides protection against earth leakage faults, short circuits, and overload conditions in low-voltage electrical distribution networks.
What is the difference between SJK47LE and SJK47LEH models?
The main difference lies in their breaking capacity. The SJK47LE model provides a rated short-circuit breaking capacity of 4,500A (4.5kA), whereas the high-breaking capacity version SJK47LEH is rated for up to 6,000A (6kA).
What instantaneous tripping curves are available?
This product series offers both C-type and D-type tripping curves. Type C (tripping at 5–10In) is standard for residential and commercial lighting loads, while Type D (tripping at 10–14In) is designed for inductive industrial equipment with high starting surge currents.
What is the residual operating current (I△n) sensitivity?
The residual current ratings range from standard human-safety protection (30mA) up to equipment protection levels (50mA, 100mA, and 300mA), all operating within a rapid breaking time of less than 0.1 seconds.
What conductor sizes and screw tightening torque are recommended?
The device features standard screw-clamp terminals suitable for copper conductors up to 25mm² (ranging from 1mm² for 6A loads up to 16mm² for 63A loads) with a recommended tightening torque of 2 N·m.
