Sécheron develops and manufactures electrical equipment to meet the needs of the mining and metals industries. We provide a broad range of products and solutions for high-voltage circuits to ensure the safe, reliable, and efficient operation of equipment like the DC machine drives found in hoists, grinding mills, and rolling mills. Our products and solutions ensure:
- Protection and safety: DC circuit breakers protect the armature of the DC machine from overload and short circuit currents, safely disconnecting the DC machine from the rectifier in the event of a fault; unlike a fuse, the DC circuit breaker is simply reclosed after a mains shutdown to ensure maximum uptime. Our disconnect switch ensures safety maintenance.
- Flexibility: All breakers are available with either an electric or magnetic holding mechanism; the magnetic mechanism remains closed without a control current. An optional indirect release can be used as an independent tripping unit for increased flexibility.
- Reliability: All breakers are available with a direct overcurrent release that can be adjusted to higher thresholds than the accepted short-time overload current during start-up and load changes to avoid nuisance tripping during operation; in the event of a severe system fault, the direct-overcurrent release rapidly opens the main contacts to interrupt the short circuit current even at maximum supply voltage.
