Command and signaling
TM-C, TM-S, TM-I control, isolating and safety transformers

TM-C control transformer
Transformer for supplying control circuits, for example commands, signaling, interlocks, etc.
Reference standard: CEI EN 61558-2-2.

TM-I TM-S safety transformer
Isolation transformer for supplying safety extra low voltage circuits (<50 V on no load).
Accidental contact with the secondary winding phases can be withstood without any
6
danger. Reference standard: CEI EN 61558-2-6
TM-I isolating transformer
Transformer in which the primary and secondary windings are electrically separated by
a double or reinforced insulation, to protect the circuit supplied by the secondary against
hazards due to accidental simultaneous contact with earth and live parts, or grounded parts
that may become live in the event of an insulation fault.
TM-S
Reference standard: CEI EN 61558-2-4

Since TM-C, TM-S and TM-I transformers are not provided with built-in protection, they must
therefore be protected according with these rules:
• Primary: line protection must reach or exceed the recommended value in Chapter 6 of
Electrical installation solutions for buildings - Technical details. This device guarantees line
protection and service continuity but doesn‘t protect the transformer.
• Secondary: transformer protection must be chosen according to tables in the previous
pages. This device protect the transformer.
