Schneider Electric RM17TG20 Harmony Control Relay – 3-Phase Supply Control, 208…440 V AC, 5 A, 2 C/O

製品説明

The Schneider Electric RM17TG20 is a modular 3-phase supply control relay from the Harmony Control Relays range, designed to monitor phase sequence and detect total loss of phase in three-phase power systems. It is self-powered from the measured voltage, accepting a nominal supply of 208…440 V AC (operating range 183…484 V AC) at 50/60 Hz ±10%. The relay provides two changeover (2 C/O) output contacts rated 5 A nominal current and 1250 VA maximum switching capacity. It features a maximum response time of 100 ms on fault appearance and a 500 ms pick-up delay. The 17.5 mm modular width matches a single-pole circuit breaker, simplifying panel design, while a transparent cover protects settings from tampering. Typical applications include hoisting, packaging, lifts, textile machinery, pumping, and water treatment systems requiring reliable phase monitoring[reference:0][reference:1].

標準機能

• Phase Sequence & Total Phase Loss Monitoring: Continuously verifies the correct L1-L2-L3 sequence and detects the total loss of one or more phases, protecting three-phase equipment from supply faults[reference:2].
• Self-Powered from Measured Voltage: Requires no separate auxiliary supply; the relay draws its operating power directly from the monitored three-phase circuit within 183…484 V AC[reference:3].
• 2 C/O Output Contacts, 5 A: Two changeover contacts rated 5 A nominal current and 1250 VA maximum switching capacity provide flexible control and signalling options[reference:4].
• Fast Fault Response (100 ms): Detects and reacts to phase faults within 100 ms maximum, with a 500 ms pick-up delay to avoid nuisance tripping during supply stabilization[reference:5].
• 17.5 mm Modular Width: The same width as a single-pole circuit breaker, enabling compact panel layouts and straightforward DIN rail integration alongside protective devices[reference:6].
• Transparent Setting Cover: A transparent cover protects the front settings from tampering and accidental adjustment, reducing maintenance interventions[reference:7].
• High Mechanical Durability: Rated for 30,000,000 mechanical operating cycles and 10,000 electrical cycles, with a yellow LED indicating relay output status[reference:8][reference:9].
