1. Application of OM8 Moulded Case Circuit Breaker (NS, MCCB)
OM8 series moulded case circuit breaker is one of breaker which adopts international ad-vanced design, manufacture technology to develop. The rated insulating voltage is 750V, suit-able for AC 50Hz(60Hz), rated working voltage 690V or below, rated working current is 12.5A to1250A of circuit and used in distributing electric energy, and non-frequent breaking in the nor-mal conditions , protecting the current& equipment from overload& under voltage, circuit breakerwith rated frame current 400A or below, can be used in mousecage motor' s non-frequent start, breaking during working, protecting motor from overload, short circuit& undervoltage, the prod-uct conforms to IEC60947-2 standard.
