Trip class adjustability and thermal protection
The 3RA6120-1CP33: Trip Class is field-adjustable between CLASS 10 and CLASS 20 — set CLASS 10 for standard motor starts (pumps, fans) and CLASS 20 for high-inertia loads (conveyors, crushers) where the start current tail lasts longer. Two integrated LEDs give local status indication — no need to open the panel door to check the starter state.
Mounting and environmental ratings for panel integration
Rated for degree of pollution 3, meaning it handles conductive dust and condensation typical in industrial enclosures without conformal coating. Vibration resistance tested to 20 m/s² at 5.8-500 Hz and shock resistance to 6g (60 m/s²) per 3 shocks in all axes — holds up on machine-mounted panels near rotating equipment.
Sourcing and lifecycle — current production, quoted to order
The main circuit uses plug-in connections without terminals, so the base unit ships without screw terminals — order the matching terminal block separately if your panel wiring requires screw-clamp terminations. Volume pricing and lead time confirmed at RFQ against your BOM quantity — no minimum order threshold for this active line item.
