Schneider Electric RM17TU00 Harmony Modular Multifunctional Three-phase Power Control Relay 5A 1CO 208...480 V AC

1. Overview of the Schneider Electric RM17TU00

The RM17TU00 is a three-phase grid monitoring relay (phase sequence + phase loss + undervoltage). It breaks down the 208–480 V industrial voltage into three alarm levels in real time: phase sequence, phase loss, and undervoltage. If any of these levels are violated, the SPDT relay immediately trips within 40 ms, preventing motor reversal or burnout.

Tool-free installation: snap onto a 35 mm DIN rail, connect a three-phase power source, and wire the load circuits, and you're online in three minutes. The internal true RMS measurement chip filters out harmonic interference, and the -25…+60°C wide operating temperature and IP20 housing ensure rock-solid reliability in dock cranes, cold storage compressors, and agricultural irrigation pump stations. UL, CSA, GL, and CE certifications ensure immediate approval for export projects, eliminating the cost of repeated testing.

2. Core Features:

• Model: RM17TU00
• Function: Three-phase grid monitoring relay (phase sequence + phase loss + undervoltage)
• Supply range: 208 – 480 V AC (50/60 Hz), no auxiliary power required
• Undervoltage setting: 0.8 – 0.95 × Ue (rotary knob adjustment)
• Phase sequence detection: Automatic positive/reverse sequence detection
• Phase loss detection: Triggered when any phase is lost
• Response time: ≤ 40 ms
• Output contact: 1 × SPDT (CO), 8 A @ 250 V AC
• Electrical life: ≥ 1 × 10⁵ cycles
• Isolation voltage: ≥ 2 kV
• Operating temperature: -25 … +60 °C
• Housing/Mounting: 17.5 mm DIN rail, IP20
• Certifications: CE, UL, CSA, GL, RCM

True RMS measurement: Automatically suppresses harmonic interference for precise readings.
Tri-color LED: Green = normal, orange = undervoltage, red = fault, providing clear on-site status at a glance.
Wide setting range: The knob allows continuous adjustment between 0.8–0.95 Ue, adapting to voltage levels in various countries.
No auxiliary power supply: Power is drawn directly from the three phases under test, simplifying wiring and saving space and cost.
