SINAMICS S150 – A Global Product
SINAMICS S150 is a global product. However, regional
differences in regulations, standards, specifications and
voltage levels for power and control require modifications
to the packaging (enclosure) and auxiliary components.
SINAMICS 150 enclosed drives are therefore offered in
versions designed to IEC (European) as well as to NEMA
(North American) standards.
SINAMICS S150 designs to NEMA vs. to IEC standards
All models of SINAMICS S150 (designed to NEMA or IEC
standards) use the identical basic drive and electronics
components – power module of a particular power and
voltage rating, CU320-2 control unit, CompactFlash card
with firmware, AOP30 operator panel as well as interface
modules (digital and analog input/output modules such as
TM31, SMC30 encoder interface, VSM10 voltage sensing
module, CBE20 Ethernet communications module, etc.).
Differences between the NEMA and IEC versions are found
in the configuration of the base units, i.e. the enclosure type
and the scope of auxiliary equipment/options included, as
well as the offered range of standard and custom options.
Below is an overview of some of the more significant
differences between NEMA and IEC versions (note this is
not a complete list!).

Base unit enclosure
and configuration
NEMA 1 (equivalent to IP21 with top hat/roof – air
discharge front and back)
Included in base for all ratings:
• Circuit breaker disconnect per NEC/UL for motor
branch circuit protection.
• Molded case circuit breaker (type VL) plus main
contactor, or motorized insulated case (type WL)
circuit breaker
• Fixed mounted fuses to meet SCCR
• SCCR per UL508A: standard 65kA for 480V,
25kA to 65kA for 600V units, large ratings
optionally up to 100 kA
• Input clean power filter
• Touch safe covers
• EMC filter Category C3 for 2nd environment
(industrial) per IEC 61800-3.
IP20 (no roof – air discharge upwards)
Included in base:
• Only for ratings >800 A, motorized (type WL) circuit
breaker. Note this is not compliant with NEC/UL
requirements for motor branch circuit protection.
• Input clean power filter
• EMC filter Category C3 for 2
nd
environment
(industrial) per IEC 61800-3
EXCLUDED from base (requires option code):
• Fused disconnect (for <800A). Note this option is
not compliant with NEC/UL requirements for motor
branch circuit protection
• Touch safe covers for smaller ratings (e.g. <400 kW,
IP20 or IP21 cabinet)
Enclosure options
• NEMA 1 filtered with louvers and dust filters
(equivalent to IP23)
• IP43 as for IEC unit
• NEMA 12 (ventilated) – louvers and fine air
filters (equivalent to IP54)
• IP21 (with raised roof)
• IP23 (with top hat, louvers & dust filters)
• IP43 (like IP23, plus 1mm mesh screen)
• IP54 (like IP23, plus fine air filters)
Exclusive standard
options
Only for NEMA version:
• UL/cUL listing per UL508A
Only for IEC version:
• Marine version, and individual marine certification
by ABS, DNV and others
• EMC filter Category C2 for 1st environment
(residential) per IEC 61800-3
