Providing electronic three phase over-current protection for systems rated through 38kV, 800A continuous current, 12.5kA symmetrical interrupting.
FEATURES
- Reliable performance, vacuum fault interrupters (for -S, -ST, -SP & LT models)
- Control flexibility including SEL-351 series, SEL-651R, GE controls and more
- Operator safety with mechanical block on trip and lockout handle
- Maintenance free operation
- Overhead, substation and dead-front pad-mount designs
- "L", "C" and "Z" style options available
- Ease of installation
- Three internal current transformers
- Up to six internal voltage sensors
- Smart Grid solutions
- RUS accepted
- Painted Stainless Steel tank
- Designed, built and tested to IEEE C37.60 and IEC 62271-111 standards latest version.
OPERATION OPTIONS
- DEAD LINE –Permits using batteries located in the control for operation when main control power is lost
- CUSTOM RELAY SOLUTIONS (CRS) – Permits using 48V DC or 125V DC control logic voltage as an alternative to traditional 14-pin SEL, Cooper & GE controls. Recloser power is not affected.
- INTERNAL VOLTAGE SENSING – Permits voltage reading for network reconfiguration applications and provides secondary analogue 120V AC output.
- MANUAL OPERATION – Hookstick operable manual trip handle trips and locks out the recloser
