Omron K2WR-R-R2 Static Reverse Power Relay for Marine Generator Protection

Omron · HMIs & Displays

Description  The Omron K2WR-R-R2 is a static-type reverse power relay designed to protect generators—particularly in marine and industrial applications—from reverse power flow. It detects reverse power conditions and disconnects the generator to prevent potential damage.     Technical Specifications  Condition New/Never Used Surplus Brand Omron  Category Protective Relays Part Number K2WR-R-R2 Subcategory Reverse Power Relays Rated Voltage 100/110/200/220 VAC Rated Current 5 A Frequency 50/60 Hz Reverse Power Setting 36 kW at 5% Operating Time (Delay) 10 seconds Power Rating 30 W Output Voltage 48 V Output Current 0.65 A Mounting Type Panel mount (typically, for this relay series) Contact Type 1a (NO) / 1c (changeover), relay output Weight 2.2 kgs       Information About K2WR-R-R2 The Omron K2WR-R-R2 is a static-type reverse power relay designed to protect generators from reverse power flow, which can occur when a generator operates in parallel with other power sources. This relay is particularly suited for marine and industrial applications, ensuring the safe and efficient operation of power systems. Key Features: Rated Voltage: Selectable between 100, 110, 200, and 220 VAC Rated Current: 5 A Frequency: 50/60 Hz Reverse Power Setting Range: Adjustable from 1.5% to 15% of the generator's rated output, in 0.5% increments Operating Time Setting Range: Adjustable from 1.5 to 15 seconds, in 0.5-second increments Detection Method: Analog time-division multiplier for high-precision power detection Control Power Supply: Not required; operates using voltage input Contact Configuration: 1a (normally open), 1c (changeover) Contact Capacity: AC220V 3A (cosφ = 0.4), DC24V 4A (L/R = 7 ms) Operating Temperature Range: −25°C to +60°C The K2WR-R-R2 is compliant with maritime standards, including JIS F 0807, and holds certifications such as NK No. 83A107 and LR No. 90/10178 (E1). Its robust design ensures reliable operation in harsh environments, making it suitable for shipboard generators and other critical power systems.
