6 FAQs about [Capacitor fire protection level classification standard]
What is the rated voltage of a capacitor?
Capacitors are applied the rated voltage at 50 Hz with 20 superimposed pulses of 2.5 kV for class X2 and 5 kV for class Y2. The rated voltage is maintained for 2 min. after the last discharge. This is a destructive test, and the failure condition is that cheesecloth around the capacitor shall not burn with a flame.
What is a low-voltage dry-type alternating current (AC) power capacitor?
This document provides standard requirements and general guidelines for the design, performance, testing and application of low-voltage dry-type alternating current (AC) power capacitors rated 1,000V or lower, and for connection to low-voltage distribution systems operating at a nominal frequency of 50Hz or 60Hz.
Are EMI capacitors UL compliant?
The reference European standard EN 132400:1995 is identical to IEC 60384-14:2013, 2nd edition. There is no specific UL standard for EMI capacitors above these ratings. The UL 1283:2005 stan-dard must be applied for UL compliance of EMI capacitors, even though it is a general standard for EMI filters. +85 °C, operating voltage > 250 V AC.
Are Knowles y2 x1 safety capacitors UL approved?
Knowles SYS family offers class Y2/X1 safety capacitors including humidity robustness grade III, 5kV impulse and a 1kVdc rating approved by TÜV and UL for use in machinery within the scope of IEC 62368. Unmarked components (UYS suffix) can be offered with a 2500Vdc rating and are designed to comply with, but are not approved to EN60384-14.
