2C200 Self Powered Overcurrent Relay

The 2C200 is a self powered overcurrent relay designed for protection applications with medium voltage ring main transformers (RMU's).

Application A

Overcurrent and short circuit/earth fault protection by combination of 2C200 and circuit breaker. Overcurrent and short-circuit stage are tripped by the magnetic coil Substitution for load break switch / fuse combination,

Application B

Overcurrent protection by combination of 2C200 with load break switch and high voltage fuses; (tripping by 2C200 disabled in range of short circuit current; disconnection by high voltage fuses)

Features

  • High accuracy numeric protection algorithm
  • “Set and forget” philosophy
  • Integrated fault log
  • Size 2M28-S1 draw out case
  • Rack-mountable modular 19” rack system
  • Automatic CT shorting when module is removed
  • Extended range of additional modules (test sockets, supervision, protection)
  • Self-test switch alarm contact for remote indication of watchdog alarm
  • On-site test of function by test button;
  • Maintenance-free, power supply by current transformer
  • Power supply buffered by lithium battery
  • Live cycle > 15 years, if current transformers are not connected
  • Made in Australia
