INSTRUMENT 6SHT-401 Instrument Transformer

INSTRUMENT 6SHT-401 is an instrument transformer designed as a current transformer for accurate, isolated current sensing in industrial electrical systems. It delivers a 400:5 A primary-to-secondary ratio and is rated for up to 600 V AC, enabling high primary currents to be stepped down to a 5 A secondary for meters, relays, and protection equipment. This configuration supports reliable metering and protective relays in switchgear, motor control centers, and distribution panels where safe, compatible instrumentation is required. As with most current transformers, the 6SHT-401 provides galvanic isolation between the high-current primary conductor and the measurement or control circuitry, helping to protect personnel and equipment while feeding standard 5 A sensing devices. Part of INSTRUMENT’s instrument transformer family, the 6SHT-401 is commonly used in industrial control panels and power monitoring setups to enable accurate current measurement with widely adopted 5 A instruments.
