Phase sequence sensor 230/400V AC Type: CKM-01 EXT10000019

Phase sequence sensor – protect your electrical installation

This CKM-01 phase sequence sensor relay from Zamel is a reliable device that will protect your electrical installation and connected devices (e.g., motors) from the effects of incorrect power supply network operation. It is used to monitor phase sequence, detect phase failure and voltage asymmetry, which helps avoid serious damage and downtime. Mounting on a TH-35 rail simplifies integration with an existing distribution board.

Functionality and application

The CKM-01 device is designed to operate in three-phase networks with a voltage of 230/400V AC. Thanks to the adjustable trigger threshold (asymmetry), you can adjust the sensor's sensitivity to the specific operating conditions of the installation. The switch-off delay and voltage hysteresis minimize the risk of false alarms caused by short-term voltage fluctuations. Optical signaling using LEDs (green – correct phase sequence, red – incorrect) facilitates quick problem identification.

• Protection against:
  • Incorrect phase sequence
  • Phase failure
  • Voltage asymmetry
• Adjustable trigger threshold: Allows you to adjust the sensitivity to the needs of the installation.
• Relay output: A single changeover contact with a capacity of 10A / 250V AC provides the ability to control other devices or alarm signaling.
• Mounting: Easy mounting on a standard TH-35 rail.
• Wide range of applications: Ideal for protecting motors, pumps, furnaces and other three-phase devices.

Technical characteristics and construction

The CKM-01 sensor is characterized by a compact design (width 17.5mm) and high reliability. Made of high-quality materials, it ensures long-lasting and trouble-free operation in various environmental conditions (operating temperature: -20 ÷ +60°C). Connection wires with a cross-section of 0.2 to 2.5 mm² provide flexibility during installation. The device meets the requirements of PN-EN 60730-1 and PN-EN 60730-2-1 standards, which guarantees its safety and compliance with applicable regulations. Power is supplied from phase L1.
