ABB 1SCD014777R1 CS Contactor, 4P, 440-480V AC - UL1008
Part Number: 1SCD014777R1
Quick Summary
ABB 1SCD014777R1 CS Contactor is a high-current device designed for reliable motor control and power distribution in industrial environments. Customers frequently wrestle with achieving dependable switching at 440-480 V AC while preserving a four-pole configuration and safe isolation during maintenance. This device carries UL1008 certification with cULus listing and aligns with ETIM EC000066 while also meeting WEEE category 4 requirements for responsible disposal. From an operational perspective, the 4P, switched-neutral configuration and delayed transition deliver safer, more predictable coil response, reducing unplanned downtime and maintenance costs. In addition, easy sourcing through CMRT data and clear logistics, including crate packaging for single-piece orders, supports streamlined procurement and faster project startup. This combination of electrical robustness and supply-chain transparency translates to measurable business value for OEMs and service teams.

FAQs
ABB 1SCD014777R1 CS Contactor is suitable for three-phase four-wire (3P4W) installations such as conveyors, pumps, and HVAC drives. Its 4P design ensures coordinated switching across all poles, while the 400 A rating provides ample headroom for motor start currents. It simplifies spare parts and reduces wiring complexity in control panels.
Key specifications include a 400 A ampere rating, 4P configuration, 440-480 V AC operation, and switched neutral. Safety certifications include UL1008 with cULus listing, ensuring compliance with North American standards. It also references ETIM EC000066 for power contactors and WEEE Category 4 for end-of-life considerations.
Switched neutral allows controlled disconnection of neutral circuits for safer maintenance and test procedures, while delayed transition minimizes arcing and mechanical wear during switching. Together they improve contact life, reduce transient stresses on downstream protection relays, and enhance reliability for high-inductive loads common in industrial drives.
Integration is supported by the 77A-2008 ZTSDSE electrical schematic reference, which provides clear wiring guidance for 30-1200 A configurations. This diagram, along with CMRT data, helps ensure correct field wiring, faster commissioning, and easier future maintenance for 3P4W motor control applications.
ROI benefits include reduced downtime from higher reliability, fewer spare parts, and faster project startup due to standardized wiring and documentation. Maintenance is simplified by clear CMRT and wiring diagrams, enabling straightforward replacement of a single high-current contactor rather than multiple components, while UL1008 compliance minimizes regulatory risk.
