Technical specifications

Typical applications

• Main and sub-main distribution boards (MDB / SMDB)
• Transformer, generator and ATS panels
• Pump, HVAC, chiller and elevator feeders
• Factories, malls, hospitals, towers and data centres
• Replacement of old MCCBs in existing switchboards

Selection guide

Choose the rated current according to the cable and the load, the breaking capacity (Icu) higher than the prospective short-circuit current at the installation point, and the number of poles according to the earthing system. Use 4-pole breakers where the neutral must be switched or protected, and check discrimination with downstream MCBs.

Frequently asked questions

What is the breaking capacity of the LV540510?

The LV540510 (CVS400N) has a breaking capacity of 50 kA at 380/415 V AC.

What is the difference between MCCB and MCB?

MCCBs cover higher currents (typically 16 A to 1600 A), higher breaking capacities and often adjustable protection, while MCBs are used for final circuits up to 125 A.

Which accessories fit this breaker?

EasyPact CVS breakers accept auxiliary/alarm contacts, shunt (MX) and undervoltage (MN) releases, rotary handles and terminal shields from the same range.
