65kA 1 Second Short Time Withstand Current Specification

Feature & Principle

65kA×1s is short-time withstand current (Icw). It means equipment can bear 65kA short-circuit current continuously for 1 second without thermal damage. This index is used to verify busbar, circuit breaker, disconnector and cabinet’s thermal stability under short-circuit fault.

Specifications

Model: 65kAx1s Parameter: Icw = 65kA, duration 1s Applicable system: AC low voltage distribution Purpose: Short circuit thermal stability check Application: Air circuit breaker, MCCB, busbar, switchgear Certification: N/A

Components & Diagnostics

This is an electrical performance parameter instead of physical spare part. Common abnormal: over-temperature after short-circuit, contact melting, insulation breakdown.

Product Brief

65kAx1s short-circuit withstand specification, electrical parameter widely used for low voltage switchgear and busbar design and spare matching.
