ASCO 400147-221-D Coil

The ASCO 400147-221-D is a high-performance 24VAC 60Hz solenoid coil engineered for continuous duty in demanding industrial and HVACR applications. This replacement solenoid coil features Class F insulation, providing superior thermal resistance and protection against electrical breakdown in high-ambient environments. Designed for seamless integration, the 400147-221-D is the direct replacement for 400115-221-D, ensuring exact mechanical and electrical compatibility without the need for field modifications. This red hat solenoid coil utilizes a molded epoxy construction to encapsulate the windings, protecting the internal components from moisture, vibration, and dust common in mechanical rooms. Technicians should verify that the 24V AC coil voltage matches the control circuit specifications before installation. With its DIN plug connectivity or lead wire options, it provides a stable magnetic field for reliable valve actuation and consistent pressure regulation across various fluid control systems.

• Direct Interchangeability: Precisely replaces the ASCO 400115-221-D, maintaining system integrity and reducing downtime.
• Industrial Grade Insulation: Features Class F construction rated for high-temperature cycles and long-term continuous duty.
• Voltage Precision: Optimized for 24VAC 60Hz systems to ensure low power consumption and minimal heat generation.
• Rugged Encapsulation: The coil is molded with high-strength epoxy to resist environmental stressors and electrical surges.

Is the 400147-221-D compatible with any ASCO Red Hat valve body?
It is specifically designed for the ASCO Red Hat valve series that utilizes the 4001xx coil frame. Always cross-reference your valve prefix and size to ensure the solenoid stroke and force requirements are met.

Can I use this 24VAC coil in a 24VDC circuit?
No. Using a 24VAC 60Hz coil on a DC circuit will lead to immediate overheating and potential coil failure due to lack of inductive reactance. Always match the pilot signal frequency and voltage exactly.

What is the primary difference between the 400147-221-D and the older 400115-221-D?
The 400147-221-D is the modern technical equivalent with updated insulation materials, offering the same electrical footprint and mounting dimensions for a drop-in replacement.
