Information About 8903SMG61V02
The 8903SMG61V02 belongs to the “Type S” electrically-held lighting contactor range from Square D (now under Schneider Electric). It is built for commercial lighting applications requiring fusible disconnect protection and robust operational control. The unit includes a 110/120 VAC coil (50/60 Hz) and is rated for 600 V fuse protection on three poles, making it suitable for large-scale lighting panels or industrial power distribution systems. Its NEMA 1 painted steel enclosure is designed for indoor control-panel mounting, and although listed as “Non-Stock” it supports legacy installations still requiring genuine parts.
Key Features:
- 600 VAC Fuse Rating: Accepts Type R fuse up to 30 A at 600 V for protected switching of lighting loads.
- 30 Amp Line Current: Rated to handle up to 30 A on each of three poles for sizeable lighting or electrical circuits.
- Three-Pole Configuration: Provides three simultaneous switching paths suitable for three-phase loads or multi-circuit lighting banks.
- 110/120 VAC Coil (50/60 Hz): Coil operates at 110 V AC for 50 Hz systems or 120 V AC for 60 Hz systems—supports both common power standards.
- Type S Contact Mechanism: Electrically held design uses no mechanical latch—reliable control and clean operation.
- Indoor NEMA 1 Enclosure: Painted sheet-steel housing rated for indoor control-panel use, streamlining installation in lighting control gear.
- Lug Terminals: Provides robust lug-type electrical connections ensuring firm wiring termination and low contact resistance.
- UL Listed & CSA Certified: Complies with recognized industrial safety certifications, file number E16151, CCN NRNT.
- Legacy/Obsolete Availability: Although marked “Non-Stock” and discontinued for new production, the model continues to support legacy systems requiring exact replacement.
The 8903SMG61V02 delivers the reliability and precision required for heavy-duty lighting contactor applications in industrial and commercial electrical systems.
