Product Description

Product Description

Molded Case Circuit Breakers are one of the primary power handling devices available in industrial environments. MCCBs can also be identified as a ruggedized and superior version of domestic miniature circuit breakers. Miniature Circuit Breakers (MCBs) are primarily found in domestic power distribution boards to control electrical power applied to different circuits within a premise.

Technical Parameters

Parameter	Description
Rated Frame Current (Inm)	This is the maximum current that the MCCB can handle. This is typically the maximum value of the adjustable tripping current range.
Rated Current (In)	This is the breaker tripping current. This value is less than the rated frame current and is adjustable.
Rated Insulation Voltage (Ui)	Insulation voltage is the maximum withstandable voltage that the breaker housing can handle. This is measured under laboratory conditions.
Rated Operating Voltage (Ue)	Continuous operating voltage of the MCCB. This is the typical system voltage and can be lower.
Rated Impulse Withstand Voltage (Uimp)	Rated impulse withstand voltage is the voltage that the MCCB can handle during a surge event such as a lightning strike. The testing is standardized for a 1.2/50 microsecond impulse.
Short Circuit Breaking Capacity (Ics)	I_cs is the highest fault current an MCCB can handle without damaging the unit permanently. The device must always be used below this limit.
Mechanical  Endurance	This provides an estimation of manual on/off cycles before the mechanical lever system fails.
Electrical Endurance	Electrical life provides a figure on how many times a unit can trip before it needs replacement.

WORKING CONDITIONS
