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.

The TemBreak series offers the models of the 800A to 1600A frames with the breaking capacity up to 125 kA, and this series consists of thermal adjustable type and electronic type that allows you to select the most suitable breaker for your system
Features of the TemBreak Electronic Moulded Case Circuit Breaker:
- Long time delay trip, short time delay trip, and instantaneous trip are available as standard.
- All of long time delay trip, short time delay trip, pretrip alarm, and ground fault trip can be adjusted. The rated current can be adjusted in a range between 50% and 100%. For short time delay trip, ramp characteristics can be selected with the switch to enable selective coordination with lower breakers and fuses.
- The multi-protective device uses the r.m.s. value control. It samples peak current every 0.5msec. to calculate a root-mean-square value. Therefore, harmonics up to 19 th harmonic are accurately detected at 50 Hz to prevent any malfunction from occurring due to harmonics.

Circuit Breaker and Transient Voltage Surge Suppressor
The Siemens circuit breaker and transient voltage surge suppressor is comprised of a highly effective TVSS module integrated with (2) 1-pole circuit breakers. This device incorporates the robust features of our secondary circuit breaker surge arrester with a lower clamping voltage ratings.
Two red LED indicator lights are provided to show that surge protection is provided for all circuits connected to the panelboard. As a Siemens exclusive feature, the device notifies the owner of loss of surge protection by tripping one or both of the circuit breakers. These breakers should be used for circuit protection of frequently used household or facility circuits because the lights and devices connected to these circuits provide an effective indication that surge protection is being provided.

Maximum safety and continuity of the electric power supply
REC2 is a self-reclosing system that uses consecutive time sequences, with an additional insulation control capacity, so that it does not reclose the unit until the problem has been solved. Therefore, it maintains the highest continuity of the electrical service under the maximum safety levels, with the minimum number of reclosures needed when the electrical installation requires so. Years of experience in these applications leads us to:
- A safe earth leakage protection unit.
- Maximum self-reclosing guarantees.
- More compact and modular.
The new REC2 can act in two ways, according to prior selection:
- Self-reclosing, by time (various reclosure attempts in a time sequence)
- A second option is that once the earth leakage system has tripped, the unit checks if there is a leak, measuring the insulation of the installation before the self-reclosing process is carried out.
The system guarantees the maximum continuity of the electric power supply in homes, shops, industries, etc. while it guarantees the protection against any form of earth leakage.

Residual current circuit breakers EFI are used for protection against indirect touching of parts under voltage, for
prevention of lasting voltage on earthed parts which should appear because of a defect in the electrical installation
and for protection against direct contacts of parts under voltage in case of I < 30mA. Residual current circuit breakers
can be used in TN-S, TN-C, TT and IT network systems or with other words in all systems where neutral and protective
conductor are separated (VDE 0100 Teil 410).
Types - Our programme comprises residual current circuit breakers which are sensitive to alternating residual current
(AC-type) and residual current circuit breakers which are sensitive to alternating and pulsating direct current (A-type).

The CVB Series vacuum circuit breaker is the main electrical switch and protection device of AC locomotives and electric multiple units. Mode of operation: The energy required to switch on the CVB is stored by a spring. It takes only a small pulse energy to unlock the main spring release latch and set free the stored energy. As soon as the supply voltage is applied, the spring gets recharged in less than 10 s. When no control voltage is being applied, the vacuum circuit breaker is in switched off position and the spring remains charged and ready for the next switching operation.
Features:
- Electrically driven vacuum circuit breaker
- No secondary supply energy like pressurized air required
- Versions for 15 kV to UIC 550 available
- Following the fail safe principle
Application:
- AC main switch in electric locomotives and EMUs
