Circuit breakers for equipment (CBE)
1 Scope
This document applies to mechanical switching appliances designed as "circuit breakers for equipment" (CBE) for household and similar purposes. The settings specified in this document
Backup circuit breakers are intended to provide protection for circuits within electrical equipment, including its components (e.g. motors, transformers, internal wiring).
This document also applies to equipment circuit breakers that protect electrical equipment in undervoltage and/or overvoltage conditions. This document also covers information applicable to
Use circuit breakers to isolate equipment.
Note. The term "equipment" includes appliances.
Equipment circuit breakers are not suitable for overcurrent protection of building wiring installations.
Equipment circuit breakers to which this document applies.
---The rated voltage does not exceed AC 440V (phase-to-phase) and/or DC 250V;
---The rated current does not exceed 125A;
---The rated short-circuit capacity is at least 6In (AC) and 4In (DC), but not more than 3000A.
The equipment circuit breaker may have a limited short-circuit current rating (Inc) associated with the specified short-circuit protective device (SCPD). set up
See Appendix F for guidance on cooperation between standby circuit breakers and SCPDs connected to the same circuit.
For protection levels higher than IP20 in IEC 60529, and often in places with harsh environmental conditions (such as excessive humidity, overheating, excessive cold or dust)
Sedimentation) and circuit breakers for equipment used in hazardous locations (such as locations prone to explosions) may require special structures.
This document contains all the necessary requirements to ensure compliance with the operating characteristics required by type testing for this type of electrical characteristics. This document also includes
Include details related to test requirements and test methods required to ensure the retestability of test results.
This document states.
a) Characteristics of equipment circuit breakers;
b) Equipment circuit breakers should meet the following conditions.
1) Operation and working conditions during normal operation;
2) Operation and working conditions under overload;
3) Operation and working conditions during short circuit at rated short circuit capacity and below;
4) Dielectric properties;
c) The tests used to confirm compliance with these conditions and the methods used in the tests;
d) Data of the mark on the electrical appliance;
e) Test procedures and number of test samples submitted for certification purposes (see Appendix C);
f) Routine testing conducted to reveal impermissible changes in materials or manufacturing that may affect safety (see Appendix I).
