SC and SC-NEXT magnetic contactors and thermal overload relays up to 660 V
Country: Japan · Model: SC / SC-NEXT
SC magnetic contactors and SW starters for voltages up to 660 V control induction motors of pumps, fans, compressors and conveyors and switch loads in automation cabinets and switchgear assemblies. The range covers frame sizes from SC-03 to SC-N16, and for North America the SC-NEXT series is made with thermal overload relays for motors of 5–50 hp at 480 V AC.

Description
The small SC-03…SC-N3 accept snap-on auxiliary contact blocks, coil surge suppressors and operation counters, so the circuit can be modified right in the cabinet. From SC-N6 and above there is the electronic SUPER MAGNET electromagnet with a built-in chip, working on the principle of AC input and DC operation. The coil is supplied with AC or DC, and after closing, an electronic pulse circuit regulates the holding current, so consumption drops sharply, the coil does not burn out and the contacts do not chatter during voltage fluctuations. Frame sizes SC-N1…SC-N5A are made without SUPER MAGNET. The compact enclosures have an arc-extinguishing system with high switching capacity and a long service life. The SC-NEXT replaced the Orange Line and Odyssey series (since 1999), its terminal covers are standard, and a part number converter is available for the changeover. The devices comply with IEC 60947-4-1, EN 60947-4-1, JIS C 8201-4-1, UL 508, CSA C22.2, CCC (GB 14048.4), NEMA, VDE 0660 and BS and are TÜV certified, so a cabinet with them can be supplied to different markets.
How to choose
The frame size is chosen by motor current and power and by the type of voltage in the control circuit. If the coil will be supplied with DC or the control voltage is unstable, take SC-N6 and larger with SUPER MAGNET, and for small drives SC-03…SC-N3 is enough. Equipment for North America is fitted with the SC-NEXT for 5–50 hp at 480 V AC. The line is protected against short circuits not by the contactor but by a G-TWIN moulded-case circuit breaker for 32–800 A.

FAQ
Can the coil of an SC contactor be supplied with DC?
Yes, in frame sizes from SC-N6 and above with the SUPER MAGNET electromagnet the coil accepts both AC and DC. SC-N1…SC-N5A are made without this electromagnet.
How does the SC-NEXT series differ from SC?
The SC-NEXT is intended for North America, covers motors of 5–50 hp at 480 V AC and is supplied with terminal covers included.
Which accessories can be fitted to the small SC-03…SC-N3 contactors?
Snap-on auxiliary contact blocks, coil surge suppressors and operation counters. They are fitted with a click right in the cabinet.
Are SC contactors suitable for equipment exported to the USA?
Yes, the devices comply with UL 508, CSA C22.2 and NEMA. For North America there is also a separate SC-NEXT series with thermal overload relays.
