Combination Starters — Through the Door Operated
Smart and cost effective... for any application
Sprecher + Schuh's new through-the-door operated combination starters represent an economical alternative to the classic flange-operated combo solution. It is designed to meet new rigid UL/NEC withstand specifications. Sprecher + Schuh has been building custom control panels with this design for years. Experience the durability of this product!
Starting with the best
At the heart of all combination starters is the Sprecher + Schuh CAT7 and CAT6 line of motor starters. These starters are compact and offer intermediate sizes to better match specific motor requirements. This equates to generous wiring space and less wasted horsepower capacity.
Top line protection...
Combination starters are equipped with Sprecher + Schuh's new state of the art CEP7 solid state overload relay. CEP7 solid state overload relays measure motor current directly through integrated current transformers and on board electronics (AISC). The electronics provide numerous advantages over electromechanical relays such as increased accuracy, a wider adjustment range, and running at a cooler temperature.
Choice of Disconnect
Choices for disconnect include either a Thermal Magnetic Molded Case Circuit Breaker (MCCB), or Motor Circuit Switch, fusible L10 or non-fusible L10 switch.
| Function | MCCB | Fusible | Non-Fusible |
|---|---|---|---|
| FVNR | C37 | C39 | C41 |
| FVR | C37 | C40 | C42 |
Thermal Magnetic Molded Case Circuit Breaker (MCCB)
The through-the-door operated combo MCCB is available to meet new UL short circuit withstand specifications. An MCCB prevents single phasing by simultaneously opening all three phases when a fault occurs in any one phase. An MCCB can often be reset after the fault has been cleared.
L10 Disconnect Switch
The through-the-door operated combo is available with the L10 switch. A mechanical door interlock system prevents the door from being opened when the disconnect is closed, and conversely, prevents the disconnect from being closed when the door is open. Both functions can be defeated for test and maintenance purposes. Other safety features include padlock provisions and a high visibility operating handle. The L10 Switch disconnects have a quick make/quick break, non-teasing action. The L10 fusible switch is suitable for interrupting up to 100,000 amperes when class "J" fuses are used. L10 disconnect switches conform to UL 98 standards (100A-400A) switches and UL 1087/489 standards (30 and 60 A switches).
Choice of Enclosures
Available enclosures include Type 1 General Purpose, Type 3R Raintight, Type 12 Dusttight and Type 4 Watertight and Type 4X corrosion resistant.
