Frequently Asked Questions

Q What is the difference between the SJK47LE and SJK47LEH models?
The SJK47LE has a rated short-circuit current (Icn) and operating short-circuit breaking capacity (Ics) of 4500A, while the SJK47LEH is a higher-capacity version rated at 6000A for both values. Both models cover the same current range of 6~63A.
Q What residual current (earth leakage) settings are available for the SJK47LE-63?
The SJK47LE-63 supports four rated residual operating current (I△n) settings: 30mA, 50mA, 100mA, and 300mA. The corresponding rated residual non-operating currents (I△no) are 15mA, 25mA, 50mA, and 150mA respectively. The breaking time at I△n is less than 0.1 seconds.
Q What is the difference between C Type and D Type instantaneous overcurrent release?
C Type trips instantaneously when the current reaches 10In (does not trip at 5In within 0.1s). D Type trips instantaneously when the current reaches 14In (does not trip at 10In within 0.1s). C Type is suitable for general residential and light commercial loads, while D Type is designed for equipment with high inrush currents such as motors and transformers.
Q What copper conductor cross-sectional area should be used with a 63A rated current?
For a rated current of 63A, a copper conductor with a nominal cross-sectional area of 16mm² is recommended. The connection method uses screw-clamp terminals with a tightening torque of 2N·m. Conductors up to 25mm² are supported.
Q What pole configurations are available for the SJK47LE-63?
The SJK47LE-63 is available in 1P+N, 2P, 3P, 3P+N, and 4P configurations. Single-pole and 2-pole variants are rated at 230V, while 3-pole, 3P+N, and 4-pole variants are rated at 400V.
Q What are the overcurrent protection characteristics of the SJK47LE-63 under normal temperature conditions?
At 30°C~35°C ambient temperature: the breaker will not trip at 1.13In for up to 1 hour (cold state); it will trip within 1 hour at 1.45In (immediately following the previous test). At 2.55In from cold state, breakers rated ≤32A trip within 1s~60s, and those rated >32A trip within 1s~120s.
