Schneider Molded Case Circuit Breaker Powerpact Series Instruction Manual

Schneider Molded Case Circuit Breaker Powerpact Series Overview

This series of Schneider molded case circuit breakers can be divided into two models, which are H-type and J-type. Their main function is to protect them from overload or short-circuit current when used in electrical systems. damage. When the pre-defined overcurrent level is reached, the molded case circuit breaker can automatically perform the circuit breaker action, and the overload and short circuit protection functions it can achieve are provided by the loaded thermal magnetic trip system.

Schneider Molded Case Circuit Breaker Powerpact Series Parameters

◆Ultimate short circuit breaking capacity

This performance value is the maximum short-circuit current at rated voltage that Schneider circuit breakers can achieve safe breaking under standard test conditions. Therefore, when selecting a molded case circuit breaker, usually its breaking capacity rating must be equal to or greater than the actual short-circuit current at the application point of the equipment in the system. The specific technical parameters are shown in the figure below.

◆Working conditions

In order to meet the requirements of UL489 standard, plastic case circuit breakers are suitable for 50/60Hz AC systems and the temperature is 40℃ in the design, production or calibration. As the ambient temperature changes, the circuit breaker may need to make derating measures to adapt to its environment. Schneider Powerpact series molded case circuit breakers can work normally between -25°C and +70°C.

Powerpact circuit breakers are suitable for use at altitudes below 13100ft. (that is, 4000 meters), but for altitudes above 6560ft. (2000 meters), the equipment must be selected according to the drop-out table.

The H-type and J-type vibration resistance of molded case circuit breakers meet the IEC60068-2-6 standard. The amplitude is ±1.6mm from 2.0 Hz to 25 Hz, and the acceleration is ±4.0g from 25.0 Hz to 100 Hz.

Features of Schneider Molded Case Circuit Breaker Powerpact Series

◆Using universal shape design

Type H and Type J circuit breakers have the same mounting holes, handle positions and trim dimensions. The specific dimensions are shown in the figure below.

◆With high breaking capacity

The ultimate breaking capacity that the molded case circuit breaker can provide is 100kA when 480V delta connection is used, and 50kA when 600V delta connection is used.

◆Using double rotating breaking structure

All H-type and J-type molded case circuit breakers in the Powerpact series are equipped with double rotating breaking contacts, which can effectively reduce the peak current value during a short-circuit fault. In this way, the let-through current can be reduced, and at the same time, it also has a higher current-limiting capability, which can improve the protection level of the equipment. ◆With strong current limiting ability

Since Schneider molded case circuit breakers adopt a double-rotating structure, no matter what the breaking capacity of the device (D, G, J or L type) is, the electric repulsion can be quickly generated, so the device can greatly limit Short-circuit current fault, that is, the fault current is smoothly eliminated before amplification. The lower current value can reduce the peak energy, reduce the pressure caused by the fault current on the bus, and realize the full selectivity or cascade technology, which can be used in 80% to 100% rated equipment.

◆Internal operating mechanism

H-type and J-type Schneider molded case circuit breakers have a protruding link toggle mechanism, which can realize fast closing and fast breaking actions, and can also trip when the handle of the circuit breaker is kept in the ON position operating. The implementation of the three-phase crossbar design can realize the common breaking and closing operation of all poles with one operating handle. At the same time, all H-type and J-type molded case circuit breakers are basically equipped with a breaking push on the cover. -to-trip button, mainly used for manual operation to trip the circuit breaker.

◆Handle position indication

The handles of all models of the Powerpact series of circuit breakers can be in any of the three positions of closed (ON), tripped (TRIPPED) and disconnected (OFF). First push the handle to the bottom "off" position. The molded case circuit breaker can be reset, and the power supply to the load can be restored by pushing the handle to the "closed" position.

◆Trip unit

All models are basically equipped with a thermal-magnetic trip system designed to automatically disconnect the circuit when overloaded or short-circuited. Independent thermal overload and magnetic short-circuit sensors are set on each pole of H-type and J-type molded case circuit breakers.

The rated current of the thermal trip element is calibrated at a free atmospheric temperature of 104oF (40°C). According to relevant specifications, the circuit breaker can only be used up to 80% of its rated value. The specific temperature derating parameters are shown in the figure below.
