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.

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).

Yaskawa SF6 gas rotary-arc circuit breakers are rated for applications in power generating plants, substations, and industrial plants at 3.6kV to 15kV. Yaskawa SF6 gas rotary-arc circuit breakers are safer to operate than vacuum and other competitive types because a two-stage pressure switch in each of the interrupters continuously monitors the gas pressure. This series of Yaskawa SF6 gas rotary-arc circuit breakers offer excellent interrupting characteristics, comparable to air-magnetic breakers, with continuous current ranging from 600 to 3000 amps. In addition, the surgeless nature of the current interruption eliminates the need for surge arrestors to dampen voltage spikes related to current chopping and switching surges. This feature makes the Yaskawa SF6 gas rotary-arc circuit breakers ideal for the protection of motors, capacitors, and transformers. This series of circuit breakers conforms to applicable ANSI, IEC and JEC st

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.
