Description
Moulded circuit breaker for control isolation and protection of low voltage lines. Protects a circuit from damage caused by excess current from an overload or short circuit
Product characteristics
- Breaking capacity of 50kA, according to EN/IEC standard 60947-2, suitable for protection of high power industrial installations.
- Rated insulation voltage of 800V. Rated impulse withstand voltage of 8kV
- Completely flexible regolation of the protection unit by software for thermal and magnetic currents and times. Thermal protection within range of 0,2-1,0 of the rated current. Magnetic protection within range of 1,5-10 of the rated current.
- Can be equipped with releases (undervoltage and shunt releases) and auxiliary contacts, rotary handles or motor operator. Locking accessories are available.
- Diffent type of connection accessories are available: cage terminals, spreader and rear terminals. Plug-in version or draw-out configuration are possible (circuit breaker fitted with special terminals and mounted on a plug-in base).
Products benefits
Installation
- Can be mounted on plate in Legrand cabinets and enclosures. Can be converted in a draw-out version with base and conversion kit
Usage
- Megatiker platform provides a complete range suitable for high power application.
Advantages
- Same MCCB size for all versions (thermal magnetic, electronic with or without measure,with ou withour RCD).
- Adjustment of Ir, Isd, Ii, Ig, tr, tsd, tg directly on the MCCB or via software PCS, that can be downloaded from e-catalog. For 4P version: adjustment of neutral can be done on front panel or by software.
- EnerUp + Project App for smartphone and tablet available on Apple Store and Google Play, can be used to connect to the MCCB via smartphone. The MPXX02 dongle key is needed to ensure the connectivity via App. Monitoring, tests implementation and test reports are available via App.
