General / Dimensions

Type 3VU13 Manual Motor Starter Protector

Siemens 3VU13 is a 3-phase manual starter providing adjustable overload protection, optional field installed under- voltage protection, and short circuit protection.

Features

JBuilt-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.

3VU13 Enclosure Dimensions

JThe 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.

JMotor Ratings — Up to 25 HP 3- Phase and 10 HP Single Phase.

JClass 10 Adjustable Ambient Compensated Overload Protection.

JPhase Loss Sensitivity.

JUndervoltage Protection — UV trip module may be added in field.

JShunt Trip Module is also field adda- ble.

JAvailable in Open Styles, NEMA 1 and 3R, watertight, dusttight, under table, and flush mount enclosures.

J1 NO and 1 NC Auxiliary Contacts Standard.

JGroup 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.
