IEC Manual Motor Starters Overview

Section 6

Combination Starters Surion GPS1BH* and GPS2BH* Manual Motor Starters may be used as combination starters (UL508 Part IV) and have been evaluated by UL as manual self-protected combination motor starters (Type E) for applications 277/480 and below. They provide coordinated branch circuit short circuit protection consistent with Section 430-52(c) (6) of the NEC; a disconnecting means consis- tent with Section 430-109 (a) (5); a motor starter and coordinated motor overload protection (see Figure 3A). These starters may be used for controlling motors without additional upstream branch circuit protection. They may be used in place of branch devices in motor circuits only. When used in panels with multiple motor circuits, a main circuit disconnect is required in sight and within 50 feet for the protection of service personnel. Surion GPS1BH* and GPS2BH* Manual Self Protected Combination Starters may also be used with a contactor when a high number of operations are required or remote switching is desired. A combination motor starter (see Figure 3B) is created by linking the self-protected manual motor starter with an evaluated contactor that has been tested for the combination. All C-2000 contactors and mini-contactors are suitable for use with Surion starters which, when used in this configuration, are suitable as combination motor starters. Using bases and links (see page 6-12) combination motor starters may be easily assembled by distributors, OEM’s or end users. This integrated starter approach allows the user to service or replace the load switching means (contactor) and/or the interrupting/disconnecting means (Surion starter) should the need arise. For combination starter installations, the standards require a means to differentiate between a short circuit and overload trip conditions. Surion delivers this means through the use of the Short Circuit Alarm Accessory GPAE11LLA (sold separately – see page 6-7). This accessory provides specific indication of a short circuit trip condition and includes a manual reset . Add GPAPT1E terminal cover to GPS1BH* for Type E and combination starter applications.
