Mactor – 11KV
Mactor is a solid dielectric single pole vacuum circuit breaker with in built current and voltage sensors and vacuum interrupters operated with time proven magnetic actuator mechanism. This outdoor Vacuum circuit breaker is aimed to improve the reliability and quality of power with the maintenance benefits of a solid dielectric insulated device. equipped with automatic and manual trip operation, Mactor are ideally suited for primary, secondary and distribution substations.
Embedded Current and Voltage Sensors
Accurate
Embedded current and voltage sensors
Failure free
Current sensors and voltage sensors are a direct replacement to current and potential transformers. When incorporated into Metal clad switchgear it makes your switchgear failure free.
Embedded Current and Voltage Sensors
Metering
Protection
Safe
Current and voltage sensors are designed for both metering and protection, covering all your specification in one design with added benefits.
Protection Class: 5P40
Metering: 0.2s
Hydrophobic cycloaliphatic epoxy bushing (HCEP)
Solid dielectric material
Suited for heavily polluted area
Reliable and longer life expectance
UV protected
Surface arc tracking resistant
FEATURES AND BENEFITS
Ease of Installation
m-Smart reclosers are compact, lightweight and pre assembled- ready to install units significantly reducing installation time
Manual Trip Operation
Manual open and lockout operation is achieved by a handle attached to a hook stick. Pulling the handle down trips and locks out the recloser unit.
Advanced Protection and Control
m-Smart Auto Reclosers are directly designed to work with MF790c Feeder Manager for both metering and protection with IEC 60870-103, 104, 101, IEC 61850 and MODBUS protocols for communication. the controller has in built features including trip circuit supervision healthy, cold lead pick up, maximum demand control and master trip.
Failure free
m-Smart Reclosers come with embedded current sensors and voltge sensors that are built to last. Current sensors work on Rogowski coil principle and voltage sensors work on capacitive voltage divider, both do not saturate due to the absense of a ferromagnetic core.
Magnetic Actuators
m-Smart Reclosers come with magnetic actuator mechanism tested for 100,000 mechanical operations. the purpose of incorporating them in a pole top recloser is to make them maintenance free, light weight.
Hydrophobic cycloaliphatic epoxy (HPEC)
HPEC is a reliable, time proven material that has a high life expectance. it is environmentally friendly, UV protected and free of SF6 gas
