Siemens 3VU13 is a 3-phase manual
starter providing adjustable overload
protection, optional field installed under-
voltage protection, and short circuit
protection.
Features
½ Built-in Short Circuit Protection. Short
circuit protection provided by the
usual branch circuit protection device
feeding a manual starter (fuse or cir-
cuit breaker in accordance with NEC
430-52) may not protect a common
manual starter. The factory built-in
instantaneous trip of the Motor Starter
Protector will protect the starter as
well as the cable and motor during
low level faults.
½ The Manual Starters Meet or Exceed
Requirements of NEMA, EEMAC, UL,
CSA, IEC, VDE and Other International
Standards. The built-in instantaneous
magnetic trip (similar to a circuit
breaker with arc chamber) provides
self protection against low-level short
circuits.
½ Motor Ratings — Up to 25 HP 3-
Phase and 10 HP Single Phase.
½ Class 10 Adjustable Ambient
Compensated Overload Protection.
½ Phase Loss Sensitivity.
½ Undervoltage Protection — UV trip
module may be added in field.
½ Shunt Trip Module is also field adda-
ble.
½ Available in Open Styles, NEMA 1 and
3R, watertight, dusttight, under table,
and flush mount enclosures.
½ 1 NO and 1 NC Auxiliary Contacts
Standard.
½ Group Installation - UL 508.
The 3VU13 is suitable for Group
Installation at 5kA 600 volts maximum
with any fuse up to 1200 amperes or
any inverse time circuit breaker up to
1200 amperes. The 3VU13 can be
installed with or without Siemens con-
tactors type 3TF2 or 3TF30 to 3TF34
in series. For higher interrupting rat-
ings, consult Siemens.
