A20
The DIRIS A20 model provides measurement of RMS values for 3 phase current plus neutral, phase to phase and phase to neutral voltage, frequency, total active, reactive and apparent power, total power factor as well providing average and maximum values of current and power. It also measures the active and reactive engergy in 4 quadrants.
A40
The DIRIS A40 model provides measurement of RMS values for 3 phase current plus neutral, phase to phase and phase to neutral voltage, frequency, total and per phase active, reactive and apparent power, total and per phase power factor as well providing average and maximum values of current, phase to phase and phase to neutral voltage and frequency, and total active and reactive and apparent power.
FSM Series / Fast-Acting
Ferraz Shawmut has developed a true 1000V AC/DC fuse designed to protect both analog and digital multi-meters. These fuses cover all the industry’s multi-meter requirements in three easy to use amperage ratings. Good for 1000 volts AC and DC, the FSM line of Ferraz Shawmut fuses are designed for the power electronics metering and controls market.
