MiCOM E124
Auxiliary Capacitor Trip Unit
Overview
Features
MiCOM E124 trip unit can be used in all cases where a battery and charger would otherwise be necessary to trip the circuit breaker. Such is the case in substations where there is no auxiliary supply, and where protective relays draw their auxiliary power from current and voltage transformer circuits.
Thanks to the two independent set of capacitors (2*59J under 300Vdc), it allows several applications :- Energize two different trip coils
- two consecutive trips on the same trip coil
- Energize a powerful trip coil (up to 118J available)
Benefits
• Advanced communications capabilities including IEC61850 with PRP and HSR• Self-powered options on the MiCOM 10 series• Native cyber security including IEEE 1686 and NERC-CIP• Wide range of frequency protections including 16.5, 16.67, 25, 50, and 60Hz• User-friendly programmable scheme logic for custom programming• Application-specific design ensuring appropriate protection for any given application
Applications
The versatile hardware and common relay management software (EasergyStudio) allows simple configuration and installation in different applications.
