General description:
EntelliGuard® G circuit breakers are the newest line of GE low-voltage circuit breakers, the next step in the evolution of a line known for its exceptional reliability and performance. They are available in 3- and 4-pole designs rated from 400A to 6000A, with fault interruption ratings up to 150kAIC
Integral to the EntelliGuard G breakers are the new, state-of-the-art EntelliGuard TU Trip Units, which provide superior system protection, system reliability, monitoring and communications.The breaker-trip unit system delivers superior circuit protection without compromising either selectivity or arc flash protection.
The EntelliGuard breaker-trip unit system demonstrates yet again GE's core competencies in reliable electric power distribution, circuit protection and personnel protection.
Modern economic reality and the regulatory environment demand system performance while recognizing the need to protect against the arc flash hazards that expose maintenance personnel to dangerous levels of heat, electrical energy, debris from damaged equipment and concussive forces. The challenge is to provide both better personnel protection by minimizing arc flash hazards and maintain electrical power to mission-critical loads. But these objectives often seem to conflict, pitting the speed and sensitivity required to optimize safety against the sequence of operations and interlocking required to maximize power system availability.

Application - Miniature circuit breakers ETIMAT DC are
used for protection of conductors in direct current
electric circuits. 1-pole circuit breakers are used for
voltages up to 220 V d.c.
and for higher voltages (up to 440 V d.c.) 2-pole circuit
breakers with poles connected in a series.
When connecting the MCB ETIMAT DC man must pay
attention to polarity.
If connected in a wrong way, the MCB can be destroyed.
You cannot use two 1-pole MCBs instead of one 2-pole MCB.

The majority of distribution systems are designed to an ultimate circuit rating (lcu). An lcu rated MCCB provides the optimum protection in terms of safe and economical selection.
Certain applications may require protection wich is designed to the more onerous service short circuit rating (lcu).
Terasaki's TemBreak Plus range can provide a wide choice of MCCBs with superior lcs ratings up to 85kA at 440V AC.
lcu=o-co 2 full short circuits
lcs=o-co-co 3 full short circuit
All TemBreak 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.
The neutral pole of all TemBreak MCCBs are of early make / late break design. This eliminates the risk of abnormal line to neutral voltages which may damage sensitive electronic equipment.
TemBreak MCCBs from 125AF to 1600AF are suitable for isolation as defined by IEC 947-2. Positive Contact Indication (PCI) is achieved via the toggle mechanism. Padlocks can only be installed if the contacts are fully open or closed.
