T2200 3 Phase Overcurrent Relay • Protection of generators against overcurrent • Visual indication of power, pick-up and relay tripping • High precision digital countdown timer for delayed output • Accepts high supply voltage variations 60 - 110% • Cost effective and highly reliable compact design • 50 hours burn-in before final test • Operating temperature range: -20°C to +70°C • Certified by major marine classification societies • Flame retardant enclosure • DIN rail or screw mounting Application The T2200 3 Phase Overcurrent Relay has a broad application where all 3 phases or any single phase current detection will function for protection, control and monitoring. The T2200 is part of the SELCO T-Line series with modular units for protection, control and monitoring of generators, both in marine and land-based tions. The T2200 is type approved by major marine classification societies. Function The T2200 detects the highest of the 3 input currents and, if this exceeds the preset level - x IN , the pick-up LED will indicate and the delay timer will be started. Installation The supply voltage is connected to terminals 1 and 3 or terminals 2 and 3, according to the supply source. The T2200 is connected to the measuring current coming from the current transducers secondary via terminals 11-12, 13-14 and See connection diagram. The current setting can be calculated according to the following example: Overcurrent protection of a generator. Required trip level 110% Generator rating 695A Current transformer 800/5A Setting 110 x 695/800 = 96% = x IN Troubleshooting 1 If the relay is not operating please check that the power LED is on, ensuring that the supply is present. 2 Measure the supply voltage which must be compatible with the information label on top of the enclosure. 3 Measure the current levels in terminals 11-12, 13-14 and 15-16 and check that at least one of the currents is above setting. For example x IN = 2.5A 1 x IN = 5A After the preset time 3 - 30 sec. has expired, the output relay and the corresponding LED will be activated, provided that the current level was exceeded for the entire delay time. The T2200 can be provided with an extra output relay. See connection diagram. The T2200 can also be provided with a latching output relay. The latching can be reset or disabled by bridging terminals 5 and On units with two output relays, reset is done by disconnecting the power supply. Connection diagram.

Application The T2200 3 Phase Overcurrent Relay has a broad application where all 3 phases or any single phase current detection will function for protection, control and monitoring.

The T2200 is part of the SELCO T-Line series with modular units for protection, control and monitoring of generators, both in marine and land-based tions. The T2200 is type approved by major marine classification societies.

Function The T2200 detects the highest of the 3 input currents and, if this exceeds the preset level - x IN , the pick-up LED will indicate and the delay timer will be started.

Installation The supply voltage is connected to terminals 1 and 3 or terminals 2 and 3, according to the supply source.

The T2200 is connected to the measuring current coming from the current transducers secondary via terminals 11-12, 13-14 and See connection diagram.

The current setting can be calculated according to the following example:

Overcurrent protection of a generator. Required trip level 110% Generator rating 695A Current transformer 800/5A Setting 110 x 695/800 = 96% = x IN

Troubleshooting 1 If the relay is not operating please
check that the power LED is on, ensuring that the supply is present.
2 Measure the supply voltage which must be compatible with the information label on top of the enclosure.
3 Measure the current levels in terminals 11-12, 13-14 and 15-16 and check that at least one of the currents is above setting.

For example x IN = 2.5A 1 x IN = 5A

After the preset time 3 - 30 sec. has expired, the output relay and the corresponding LED will be activated, provided that the current level was exceeded for the entire delay time.

The T2200 can be provided with an extra output relay. See connection diagram.

The T2200 can also be provided with a latching output relay. The latching can be reset or disabled by bridging terminals 5 and On units with two output relays, reset is done by disconnecting the power supply.
