Full-featured & compact MCCB.
Ideal for protecting and measuring the power receiving and distribution circuit.
3 sizes and 9 frames of MCCB can cover currents rated from 100 A to 1600 A.
Compliant with international standards.
IEC60947-2, EN60947-2, JISC8201-2-1, NEMA AB1
Improved breaking performance because Ics (rated service short-circuit breaking capacity) is the same as Icu (rated ultimate short-circuit breaking capacity).
Control unit & display unit
– Abundant lineups are provided from basic type only with over current protection function to enhanced type with power quality control.
– The combination with various measuring functions, such as an ammeter, watthour meter, harmonic meter as well as with long time delay, short time delay, and instantaneous delay is possible.
– The parameter measurement & operation, data storage, log event recording, alarm output, and communication functions are possible.
Internal accessories of various rating are prepared.
(auxiliary/alarm switch, voltage/under voltage trip, etc.)
The compact external operating handle and electric control device are also prepared. Possible to change the setting of control unit while attaching a handle.
