Mechanical Features
- Mechanical operations range from 3,000 to 10,000 cycles depending on size and rating.
- Maximum weights for 3P and 3P+N configurations are available upon consultation.
Construction and Enclosure
- Available in polyester or metal enclosures.
- Protection rating IP65 (with or without fuse holders).
- Fuse holders compatible with NH fuses (sizes NH00 to NH4 depending on current rating).
Accessories and Options
- External handle included as standard; emergency external handle available on request.
- Auxiliary contacts available:
- 1NO + 1NC (Code D5LAU01)
- 2NO + 2NC (Code D5LAU02)
- Safety key lock devices:
- Simple (Code DS-CAB1, DS-CA11, DS-CB21, DS-CB31, DS-CB41 depending on size)
- Double (Code DS-CEB1, DS-CE11, DS-CE21, DS-CF31, DS-CF41)
- Terminal protection kits available for sizes 1, 2, 3, and 4 (e.g., DS-CU11, DS-CU21, DS-CU31, DS-CU41).
- 4P switch versions available on request.
Dimensions and Wiring
Dimensions vary by size and current rating, with detailed measurements provided for maximum conductor cross-section (S max), height (H max), length (L max), and torque (Nxm) for copper conductors. Typical conductor sizes range from 2.5 mm² up to 2x240 mm² depending on the model.
Recommendations and Limitations
- Consult manufacturer for mechanical operation values outside standard ranges.
- Consult for other voltages and utilization categories beyond 400V AC.
- Higher current ratings available on request for size 4 models.
- Short-circuit ratings assume no limiting protective device; protective devices recommended for enhanced safety.
