R-K Electronics, Inc. RCY6A-18V

Transient voltage filter R-C networks (resistor-capacitor) are used in circuits where transient voltage spikes may cause malfunction or damage to solid-state controls or control systems (PLC, CNC, NC, solid-state counters, etc.). RCY units are typically connected in parallel with three-phase inductive loads (motors) to absorb transients generated when the load is disconnected from the line. They also suppress electrical noise during load operation. The varistor option provides additional protection by clamping transients at a specific voltage level (maximum clamping voltage). The bleed resistor allows voltage accumulated on the capacitor in the RCY to dissipate after voltage is removed. Bleed resistors are commonly used in applications where the control device connected to the RCY may operate (be tested) without a load (motor) connected. Input voltage up to 600VAC, three-phase, 50/60Hz. Capacitance: 0.47µF, ±10%; resistance: 100 or 220 ohms, ±5%, 7W; varistor maximum allowable AC voltage: 625VAC, maximum clamping voltage: 1650V (at 50A), energy: 40 joules; bleed resistor: 1MΩ, 1/2W; power dissipation at 600VAC: 37W.
