Protection & Monitoring Relays Series
Klemsan protection and monitoring relays in new enclosures under the DIN
norm, are designed to protect your system against problems caused by voltage,
frequency, and temperature in single-phase and three-phase electrical systems.
In addition to fixed protection models that do not require any adjustments, some
products allow asymmetry, voltage protection, protection parameter selection,
and time setting adjustment over trimpots on the device
• System errors can be monitored thanks to the LED notifications that indicate
errors.
• Product design under TS EN 60255 standard,
• 18mm thin product body under DIN standard,
• TRMS measurement,
• Red LED indicators for error notification,
• Orange LED indicator for relay status,
• Adjustable pots for time and limit values,
• 5A SPDT relay output,
• Optionally Asymmetry, Phase Sequence, Absence of Phase, High - Low
Voltage, High - Low Frequency, PTC, Neutral break protection,
• Liquid level and light intensity monitoring functions
• Star, delta, and single-phase connection options,
• High precision and high mechanical durability.
