AVISO
El siguiente capítulo se imprime siempre en idioma inglés, independientemente del
idioma de esta documentación, debido a los requerimientos UL.
Observe the following notes for UL-compliant installation:
The devices are for use only in industrial machinery NFPA 79 applications.
For use in a Pollution Degree 1 or Pollution Degree 2 environmental only.
• Use 75 °C copper wire only.
• Tighten terminals to 17.7 – 21.24 in-lbs (screw connect terminals only).
Suitable for use on a circuit capable of delivering not more than 65,000 rms symmetri-
cal amperes when protected by 600 V nonsemiconductor fuses (Class CA, CB, CD,
CF, G, J, K-1, K-5, RK1, RK5, T) or when protected by 500 V minimum inverse time
circuit breakers having an interrupting rating not less than 65 kA rms symmetrical am-
peres.
The max. voltage is limited to 500 V.
Suitable for motor group installation on a circuit capable of delivering not more than
65,000 rms symmetrical amperes when protected by, 600 V maximum nonsemicon-
ductor fuses (Class CA, CB, CD, CF, G, J, K-1, K-5, RK1, RK5, T) or when protected
by 500 V maximum inverse time circuit breakers having an interrupting rating not less
than 65 kA rms symmetrical amperes.
The max. voltage is limited to 500 V.
Integral solid state short circuit protection does not provide branch circuit protection.
Branch circuit protection must be provided in accordance with the National Electrical
Code and any additional local codes.
For maximum branch circuit protection see table below.
SCCR: 65 kA /500 V when protected by
Non-semiconductor fuses
(currents are maximum values)
40 A max./600 V
The devices are provided with load and speed-sensitive overload protection and ther-
mal memory retention upon shutdown or power loss.
The trip current is adjusted to 150 % of the rated motor current.
