Short circuit current rating
Suitable for use in current circuits with a maximum short circuit current of
AC 200,000 A
eff
for the following fuses:
For 240 V systems:
250 V min., 25 A max., fuse
or 250 V min., 25 A max., circuit breaker
For 500 V systems:
500 V min., 25 A max., fuse
or 500 V min., 25 A max., circuit breaker
The maximum voltage is limited to 500 V.
Branch circuit protection
Integral semiconductor short-circuit protection does not provide branch circuit protec-
tion. Branch circuit protection must be provided in accordance with the National Elec-
trical Code and any additional local regulation.
The following table shows the maximum values for the circuit protection of branch cir-
cuits.

Motor overload protection
MOVIMOT
®
MM..D is fitted with a load and speed-dependent overload protection with
thermal memory in the event of disconnection and power loss.
The trigger threshold is 140% of the rated motor current.
Ambient temperature
MOVIMOT
®
MM..D is suitable for an ambient temperature of 40°C, max. 60°C with de-
rated 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.
INFORMATION
• Only use certified units with a limited output voltage (U
max
= DC 30 V) and limited
output current (I ≤ 8 A) as an external DC 24 V voltage source
• The UL certification only applies to operation on voltage supply systems with vol-
tages to ground of max. 300 V. The UL-certification does not apply to operation on
voltage supply systems with a non-grounded star point (IT systems).
