Berko 410171001 Relay

The Berko 410171001 Relay is a specialized 24V time delay relay engineered for precise sequencing in commercial and industrial heating systems. As an essential Marley Engineered Products replacement part, this component is designed to manage the staggered activation of heating elements, preventing high inrush current and reducing stress on your electrical distribution panel. This HVAC control relay is a direct OEM fit for Berko CUH900 series heaters and various QMark unit heaters, ensuring electrical compatibility without the need for field modifications.

Constructed for high-duty cycles, the 410171001 provides stable timing functions even in demanding environments. This low voltage heater relay simplifies the troubleshooting process for technicians dealing with element staging issues or faulty fan-delay logic. Its compact form factor allows for efficient mounting within standard control enclosures, making it a reliable choice for maintaining peak performance in forced air electric heaters.

• OEM Compatibility: Exact replacement for Berko and QMark 24V control circuits, ensuring seamless integration.
• System Protection: Effectively manages time-delayed element sequencing to protect against circuit breaker trips during startup.
• Precision Timing: High-accuracy internal circuitry maintains consistent delay intervals for optimized heat transfer.
• Robust Build: Designed to withstand the thermal cycling typical of industrial HVAC applications.

Which heater models use the 410171001 relay?
This relay is primarily utilized in Marley CUH900 and QMark S935 series heaters equipped with 24V control transformers.

Can I use this relay to replace a 120V control model?
No, this part is strictly rated for 24V AC control voltage. Verify your primary transformer output before installation.

What are the symptoms of a failing time delay relay?
Common indicators include heating elements staying energized after the thermostat is satisfied or elements failing to sequence properly during the initial call for heat.
