As to the available information, because of their extraordinary short dimensions (especially the width of only 81 mm), our P-E-P MCB´s are classified as among the smallest MCB´s over the world in the category of short-circuit resistance up to 10 kA. In the category of 15 kA, we have the shortest dimensions worldwide (see the dimensioned chart).
Thus there is more space for conducting and connecting the conductors in the installation section which is covered at a switchboard. This property can be appreciated especially when using these MCB´s at small apartment switchboards.
The limiting miniature circuit breakers BONEGA® P-E-P-15J have two different releases acting onto the switching mechanism:
|
1.) thermal over-current release for over-current protection, working with time lag |
| 2.) electromagnetic high-speed release with ejecting armature for immediate short-circuit protection |
They are suitable especially for common installation into switchboards and switching points of low-voltage end circuits. They are designed mostly for alternating current but they can be used also for direct current for which the reduction of short-circuit resistance by approx. about 20% has to be taken into account (because of a higher stress of contacts).
With their design and technical parameters, the miniature circuit breakers BONEGA® P-E-P-15J conform to the current technical top level world-wide.
They are marked with a logo with a trademark BONEGA®. It is a
traditional brand since 1992 which shall be introduced to the markets over the
world. The name BONEGA®comes from the ESPERANTO language and in that language,
BONEGA®means excellent, good.
The name of the P-E-P series conceals the English term Perfect Electric
Protector, stressing its extraordinary high quality supported by a long
guarantee).
The miniature circuit breakers are manufactured in accordance with a particular European standard CSN EN 60898, as amended. They are able to comply with any design requirements for arrangement of MCB´s with regard to the selectivity and requirements for individual characteristics B, C and D.

The MCB´s BONEGA® , series P-E-P have more than 50 user's advantages
The miniature circuit breakers BONEGA® , series P-E-P, can be mutually interconnected by means of single-pole to four-poles interconnecting forked and reed (rack) strips.
The miniature circuit breakers can be linked-up with many accessories. (low-volt releases, ejecting coils, auxiliary contacts, etc.)
All those elements extend the application of the MCB by overvoltage or undervoltage protection, control, regulation, remote control, remote indication of switch-on and switch-off positions of the circuit breaker, programming and measurement. Those combinations enable the circuit breakers to be applied in the range of control of the complicated automated processes.
These elements can be mutually interconnected (e.g. MCB + undervoltage release + auxiliary indicating contact etc.), thus they can form different combinations.

| Characteristics: | B (or L), also “V” before. The short-circuit release is to be set up to 3 ln through 5 ln. It serves especially for protection of circuits with such devices which do not cause any current surges (lights or socket circuits etc.) | ||
| C (or U), also K before. The short-circuit release is to be set up to 5 ln through 10 ln. It serves especially for protection of circuits with such devices which cause some current surges (groups of bulbs, motors etc.) | |||
| D (or M), also „---------„ before. The short-circuit release is to be set up to 10 In through 20 In. It serves especially for protection of circuit with devices which cause high current surges (transformers, double-pole motors, motors with heavy start etc.) | |||
| Nominal voltage: | 1 P (single-pole) ~ 230/400 V 50/60 Hz | ||

Protection:
|
IP 20 for a sole MCB - with its design, it protects against a hazardous finger touch as well as against small foreign objects; it is without any protection against water leakage ( water protection is to be solved with design of the switchboard casing ) | ||
| IP 40 for a built-in MCB - with its design, it protects against a hazardous finger or instrument touch as well as against very small foreign objects; it is without any protection against water leakage ( water protection is to be solved with design of the switchboard casing ) | |||
