CSPR

Self Power Relay : CSPR1

FEATURES
  • CT powered relay.
  • O/C, S/C, E/F and E/F High Set protection
  • DEFT and Inverse characteristics for O/C and E/F
  • Impulse output for tripping coil

CSE offers a wide range of CT powered relays which provide over current, short circuit,instantaneous phase and earth fault functions.CSPR-V1–1 is a compact relay specifically
designed for compact MV switchboards with circuit breakers. CSPR-V1 uses CTs with secondary rated for 1A.

Product Description :

The CSPR-V1 is a CT-powered protection relay with inverse time and definite time protection characteristics.
CSPR-V1 provides following protection functions:

  •  3 phase definite time over current and short-circuit protection with variable tripping times (ANSI 50/51)
  •  3 phase over current protection with selectable inverse time characteristics and definite time short-circuit current element (ANSI 50/51)
  •  Definite time and inverse time earth over current protection by internal calculation (ANSI 50N/51N).
  • Remote Trip input
  • Fault value memory
  • Serial communication for remote read-out on MODBUS RTU
  • Parameter setting by rotary switches
  • Inverse characteristics can be individually selected for phase and earth fault
