Wide range of relays anf transformers to protect your instalation of earth leakage, overloads, etc.
Nowadays, earth leakage devices are recognised around the world as an effective means of ensuring the protection of people against the dangers of direct or indirect contact with low voltage electrical current.
The main aim of these earth leakage protection devices is to detect faulty earth currents and to act by cutting the electrical circuit, in the event that these currents pose a danger to persons or property.

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

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).

Breaking Contacts
TemPower 2 is the world's first Double Break ACB, having two breaking contacts per phase. The unique pole structure means that the short-time withstand rating (Icw) is equal to the service short-circuit breaking capacity (Ics) for all models.
Packing Density
You can increase switchboard packing density using the smallest one second rated ACB on the market. The fixed version is 290mm deep, the drawout version is 345mm deep.
Reliability
Double Break contacts increase service life. Electrical and mechanical endurance ratings are the best available, and exceed the requirements of IEC 60 947-2.
Double Quick Opening
TemPower 2 ACBs clear short-circuit faults in less than 30ms. That%u2019s twice as fast as most ACBs.
Double Opening and Closing Coils
Now you can extend control system redundancy to an ACB. Double coils allow designers to implement back-up tripping and closing systems.
Double Neutrals
How do you make a system harmonic proof in the face of increasing triple-N harmonic currents? Terasaki have launched the first Double Neutral ACB. The AH-60DN will carry 10,000A of neutral current.
Protection Characteristics
TemPower 2 is the only ACB which offers time-current characteristics to 3 different standards:
IEC 60 947-2 (low voltage circuit breakers)
IEC 60 255-3 (electrical relays)
Lloyds Register of Shipping (for marine generator protection)
All models have LSI protection.
Double Insulation Properties
All operator controls and accessory locations are double insulated from the main phases.
ReduceTime to Repair
Modular construction means that each pole of the TemPower 2 ACB can be replaced in about 15 minutes - by the user. This unique feature will reduce downtime for end-users.

If a magnetic relay coil is opened and closed near an electronic circuit, malfunctioning of the electronic circuit could be induced by a surge voltage. The UN-SA type surge absorber suppresses the surge voltage when the coil is opened and closed. In addition to the general varistor type and the CR type that lays importance on suppressing the induction voltage when starting, the type with operating indicator (varistor type), and the varistor type with CR are available.

No electrical system can do without circuit breakers, as they are the 'stop' signs acting when too much current is flowing through electrical wiring.
In fact, they are essential devices and one of the most important safety mechanisms for the prevention of dangerous situations. The value of circuit breakers depends on which appliances are connected. You can either order a ready-made switchboard with the most common circuit breaker values, or give the installer or distributor a list of your specific values for a tailor-made solution.

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
