9 Profile Enhanced co-ordinated protection,the most flexible MCCB in the world Very often, MCCBs must grade with other protective devices that may not have adjustable characteristics. This could be either a downstream fuse or an upstream electricity authority relay. Each microprocessor based can achieve as standard over 00,000 independent time current characteristics. This unique curve flexibility enables to achieve full selectivity even in the tightest of grading systems.

All applications are met by In addition to microprocessor MCCBs being the most flexible on the market, a number of important features are available as STANDARD! Most other MCCB manufacturers offer these relevant features at a premium price. ADJUSTABLE TIME ADJUSTABLE I T RAMP ADJUSTABLE INST TRIP 0 sec T sec Upstream MCCB motor starting curve 00 msec L.V. fuse downstream I T Ramp ON I 0 msec T OFF 00% 0% Provision of adjustable LTD T settings and STD T setting are important to match the protective characteristic to the load requirement. It is also extremely useful to provide flexible grading with other devices. When co-ordinating between MCCB and fuses, it can often be difficult to obtain the required selectivity due to the different shape of the time current curves. With a flick of a switch the I t ramp can be enabled to make grading easier. Inductive loads such as motors often produce a transient inrush on initial switching. In this application it is important to have an adjustable instantaneous trip to set above this inrush current. "INNOVATORS IN PROTECTION TECHNOLOGY" 7
From A to 00A, detects true r.m.s. as standard Due to the amount of nonlinear loads such as UPS, variable speed drives, soft starters & thyristor controls the level of harmonics in L.V. distribution is substantially increasing. TRUE R.M.S. PROTECTION, UNEFFECTED BY HARMONICS I Peak value Peak value/ true r.m.s. True r.m.s Conventional electronic MCCBs incorporating 'peak detection' are prone to nuisance tripping if Harmonic distortion exists. t T T=00µsec MCCBs employ a True R.M.S. detection through a process of sampling and integrating. Even those MCCBs that claim True R.M.S. may only do so up until the rd or th Harmonic. Ignoring higher frequency harmonics can lead to 'under protection' of the conductor. By utilizing a high sampling rate of 00 µsec microprocessor MCCBs detect up until and including the 9th Harmonic. HIGH FREQUENCY HARMONICS DETECTED 0 % Total Harmonic Distortion Conventional r.m.s. detection can ignore higher frequency harmonics 7 9 7 9 Frequency spectrum PRE-TRIP ALARM FUNCTION (OPTIONAL) Output contact (a) of the pre-trip alarm Computer Essential Load Non-essential Load Non-essential Load SHT SHT Electronic office equipment is being increasingly used in today's buildings and factories. The power demand at peak time can reach overload levels of the breakers installed in the system. If such a situation continued a sudden trip may be generated by the long time-delay trip function of the breaker. The pre-trip alarm prevents this "sudden trip" by tripping out non-essential loads thus ensuring an uninterrupted supply to essential loads.
Safety you can rely on, with choice of Protection All Plugin and drawout MCCBs are fitted with a safety trip as standard. If an attempt is made to remove an MCCB while ON it will automatically trip. SAFETY TRIP (STANDARD) The neutral pole of all MCCBs are of early make / late break design. This eliminates the risk of abnormal line to neutral voltages which may damage sensitive electronic equipment. EARLY MAKE / LATE BREAK NEUTRAL MCCBs from AF to 00AF are suitable for isolation as defined by IEC 97-. Positive Contact Indication (PCI) is achieved via the toggle mechanism. Padlocks can only be installed if the contacts are fully open or closed.
