Description
The Manitowoc Ice 8505003 is a PTCR (Positive Temperature Coefficient Resistor) motor start relay rated at 10 amps, engineered as a direct OEM replacement for Manitowoc commercial ice machines. PTCR start relays are a critical component in single-phase compressor circuits, providing the momentary starting current boost needed to bring the compressor motor up to operating speed before automatically dropping out of the circuit — all with no moving parts for enhanced reliability and longevity.
Key Features
- OEM Manitowoc Ice replacement part (SKU: 8505003)
- PTCR (Positive Temperature Coefficient Resistor) motor start technology
- 10 Amp rating for dependable compressor motor starting
- Solid-state design — no mechanical contacts to wear out
- Drop-in replacement for compatible Manitowoc ice machine models
- Helps reduce compressor starting stress and extends equipment life
Application
Designed for use in Manitowoc commercial ice machines requiring a PTCR-type motor start device. Always verify compatibility with your specific model number before installation. Consult the equipment service manual or contact your Manitowoc distributor for model cross-reference information.
Why Choose a PTCR Start Relay?
Unlike traditional electromechanical start relays, PTCR devices rely on a thermistor element that increases resistance as it heats up, effectively removing itself from the start circuit without mechanical switching. This results in a more consistent start performance, reduced maintenance requirements, and improved compressor protection over the life of the equipment.
