Starters & Enclosed Products
Combination Starters — Flange Operated
The "classic" combination starter for your application
Sprecher + Schuh combination starters are, by design, intended to eliminate the purchase and assembly of a separate disconnect, starter, enclosure and associated wiring. The end result is a cost effective assembly from our custom panel shop that is cleanly wired and ready for installation.
Starting with the best
At the heart of all combination starters is the Sprecher + Schuh CAT7 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 (ASIC). The electronics provide numerous advantages over electromechanical relays such as increased accuracy, a wider adjustment range, and running at a cooler temperature. Selectable trip class is available on certain models as well as flexible field installable accessories.
Choice of Disconnect
Choices for disconnect include either a Motor Circuit Protector (MCP), or Motor Circuit Switch (MCS), fusible or non-fusible.
| Function | MCCB | Fusible | Non-Fusible |
|---|---|---|---|
| FVNR | C45 | C47 | C49 |
| FVR | C46 | C48 | C50 |
Motor Circuit Protection (MCP)
The Motor Circuit Protector is an adjustable "magnetic trip only" circuit breaker for precise protection of motor circuits. An MCP prevents single phasing by simultaneously opening all three phases when a fault occurs in any one phase. An MCP can often be reset after the fault has been cleared.
Fusible and Non-Fusible
Disconnect mechanisms are flangemounted for simple operation during start-up or maintenance. 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.
Motor Circuit Switch disconnects have a quick make/quick break, non-teasing action. The three blades are visible for positive indication of an open circuit. The fusible MCS is suitable for interrupting up to 100,000 amperes when class "R" type fuse clips and fuses are used.
Choice of Enclosures
Available enclosures include Type 1 General Purpose, Type 12 Dusttight.
