Sprecher + Schuhs CA4 Series of miniature contactors and starters provide an extremely compact and reliable method of controlling motors. The CA4 is an economical choice for applications where space is limited or where a minimal enclosure is desired.
Small but rugged. Even though their contacts and coils are not replaceable, Sprecher + Schuh has subjected this series of contactors to monitored endurance tests that demonstrate their ruggedness. At full load, under 3-phase power, the contacts in the CA4 have an electrical life of 700,000 operations, while the AC magnet system has a mechanical life of 10,000,000 operations.
This miniature starter features the new CEP7 Solid State Overload Relay, known for its superb protection, accuracy and low energy use. Rather than simulate the heat build-up in the motor by passing current through an electromechanical mechanism, CEP7 overload relays measure current directly through the use of current transformers. Their solid state design significantly reduces heat and ensures a precise and reliable tripping response even after many years of operation.
The entire CA4 System is logically engineered. Modular accessories like auxiliary contact blocks and timing elements snap-on without increasing the CA4s original width of 45mm. Also, due to its sideways switching movement, the basic contactor has the same low profile whether an AC or DC operating magnet is used. This permits the use of enclosures with shallow mounting depths. Once the CA4 is installed, all auxiliary contact blocks can be snapped-on or removed without changing any existing power wiring
Sprecher + Schuh is at the leading edge of technology, developing affordable solid state overload relays that utilize the latest Application Specific Integrated Circuits (ASICs) in their construction. This gives our new CEP7 overload relay many features that are simply not possible with traditional bi-metallic or eutectic alloy electromechanical overload relays. The CEP7s on-board electronics are constantly monitoring all three phases. If the ASIC board senses that one phase is missing during a steady state running condition on a 100% loaded motor, it will trigger in 2 seconds; and from 2 - 3 seconds on a lightly loaded motor. These times are much faster than any electromechanical overload relay.
