The max. voltage is limited to 240 V.
For 500 V systems:
500 V minimum, 25 A maximum, non-semiconductor fuses or
500 V minimum, 25 A maximum, inverse time circuit breakers
The max. voltage is limited to 500 V.
Group installation
For 240 V systems:
Suitable for group installation on a circuit capable of delivering not more than 18,000
rms symmetrical amperes when protected by 25 A maximum nonsemiconductor fuses,
Class RK5 and delivering not more than 5,000 rms symmetrical amperes when protec-
ted by 25 A maximum inverse time circuit breakers.
For 500 V systems:
Suitable for group installation on a circuit capable of delivering not more than 18,000
rms symmetrical amperes when protected by 25 A maximum nonsemiconductor fuses,
Class RK5 and delivering not more than 5,000 rms symmetrical amperes when protec-
ted by 25 A maximum inverse time circuit breakers.
Branch circuit protection
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.

The trip current is adjusted to 140 % of the rated motor current.
Ambient temperature
The devices are suitable for an ambient temperature of 40 °C, max. 60 °C respectively
55 °C (Z.9 only) with derated output current. To determine the output current rating at
higher than 40 °C, the output current should be derated 3.0 % per °C between 40 °C
and 60 °C respectively 55°C (Z.9 only).
