• Model 312; 28 binary inputs, 37 binary outputs, 6 binary outputs for tripping
- For three terminal line, With autoreclose for single breaker scheme / With fault detector
• Model 411; 28 binary inputs, 31 binary outputs, 6 binary outputs for tripping
- For three terminal line, With autoreclose for one-and-a-half breaker scheme / With fault detector
• Model 511; 28 binary inputs, 31 binary outputs, 6 binary outputs for tripping
• Model 513; 28 binary inputs, 31 binary outputs, 6 binary outputs for tripping, TFC function
Model 100 has the minimum configuration, having only the segregated phase current differential
protection, overcurrent backup protection scheme and thermal overload protection.
Models 200 through 500 have a full protection scheme including additional high-sensitivity differential
protection for high-impedance earth faults, breaker failure protection, out-of-step protection,
fault locator and autoreclose function. Models 200 and 400 have a single- and multi-shot
autoreclose function and are used for single breaker autoreclose schemes. Models 300 and 500
have only a single-shot autoreclose function and are used for one-and-a-half breaker
(two-breaker) autoreclose schemes. Models 400 and 500 have an independent fault detector in
the form of a check relay, and provide the highest security. Models 503 and 513 have a CT
saturation countermeasure against the external through fault current in one-and-a-half breaker
schemes.
