40 ELECTRONIC COMPACT STARTER | MANUAL
Group mounting
Group mounting HF-Starter results in significant space savings in control cabinets. One MO132 can be used to protect
several electronic compact starters. Please find all tested results in table 17 for 500 V AC and table 18 for 415 V AC. Two
installation proposals for group protection are shown in figure 25 and figure 26.
Please consider the sum of current of all HF-Starter must not exceed the max. current of the MO132 chosen. For example, if
the max. current is 20 A, a MO132-20 must be chosen and the sum of HF-Starter current must not exceed 20 A in total.

Group mounting – example 1
As visualized in figure 25, as a short-circuit protection device the MO132-32 is chosen. The nominal current is 32 A. Customers
now have the option to combine different current sizes and variants of HF-starters until the maximum nominal current of 32
A is reached. The sum of the nominal currents of the HF-starters must not exceed the nominal current of MO132.
Figure 25 shows that in all six units of HF9-Starter are used. The complete sum of the current of these four electronic
compact starters equals 4 * 6.5 A = 26 A. There are still 6 A 'available'. So, two additional HF9-Starter with 3 A are able to be
controlled and protected.
SCPD: MO132-32, maximal current 32 A
• Installing 4 x HF9 with each 6.5 A results in 26 A
• Adding additional 2 x HF9 with 3 A adjusted results in 6 A
• Calculation: 32 A – 26 A -6 A = 0
