OPTIM FRM-75-440 - Fixed capacitor with rejection reactance p = 7 % - Code R5Y3A0

Q: What is the main purpose of the OPTIM FRM-75-440 capacitor bank?

It is designed for power compensation in motors and transformers with constant load, where there is a high harmonic content and risk of resonance.

Q: How does the device help manage harmonics and prevent resonance?

Waste filters are tuned to 189 Hz to protect harmonics present in the network and avoid resonance phenomena with harmonics of order 5 or more.

Q: What protection features are included in the OPTIM FRM-75-440?

It provides individual protection of each step using high-rupture-power NH-00 series fuses, and it incorporates a thermostat that disconnects the step if temperature exceeds 90 °C.

OPTIM FRM-75-440 is a fixed capacitor bank with detuned filters designed for power compensation in motors and transformers under constant load, especially when the network contains a high harmonic content and resonance risk. It combines capacitor protection steps with NH-00 series high-rupture-power fuses or a circuit breaker option, includes waste filters tuned to 189 Hz to protect harmonics of order 5 or higher, and uses a thermostat trip at 90 °C. Electrical data include 440 V reinforcement, ±10% tolerance, and defined surge and overload performance, with IP 21 environmental protection.
