Presentation

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).

Benefits

• 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
