Multipurpose Relay for Applications where non-directional overcurrent and earth-fault protections are needed, e.g. - feeder protection - transformer protection - back-up protection Application areas, e.g. - power utilities - industries - marine and offshore installations

Protective Functions Three-phase, low-set phase overcurrent protection with definite time or inverse definite minimum time (IDMT) characteristic Three-phase, high-set phase overcurrent protection with instantaneous or definite time function Low-set, non-directional earth-fault protection with definite time or inverse definite minimum time (IDMT) characteristic High-set, non-directional earth-fault protection with instantaneous or definite time function Circuit-breaker failure protection

Scope

• Motor protection relay

• The relay can also be used for the protection of other objects, such as transformers and feeders, requiring a single-, two- or three-phase overcurrent and/or overload protection and non-directional earth-fault protection

Product features

• Three-phase thermal overload protection
• High-set overcurrent protection with instantaneous or with definite time operation
• Phase unbalance and single-phasing protection with inverse time characteristic
• Fast operating incorrect phase sequence protection
• Sensitive earth-fault protection with definite time characteristic
• Undercurrent protection with definite time characteristic
• Several selectable motor start-up supervision methods
• Continuous self-supervision of hardware and software
• Current range handled meets the requirements for ExE motor drives of Zone 1

Electrical characteristics

• Foundation Fieldbus (H1), according to IEC61158-2, 31.25kBit/s
• Certification: ITK 4 (Regr.-Nr.: IT 015000)
• Dual input (electrically isolated) 2 RTDs, 2 thermocouples , RTD and thermocouple combination or other user specified signals
• User specified special linearity, set by multi-point
• Redundant features such as dual sensors for increased reliability
• Sensor drift monitoring
• Explosion-proof certification: 
  intrinsically safe ATEX, FM/CSA IS and Non-incendive A pp rovals
• For type B junction box, integrated installation
• Enhanced electrical design
• Allowable ambient temperature: -40°C... 85°C
• L AS (Link Active Scheduler) for local control loop
• Local communication port for parameter simulation mode
• Local display module
