Packard TQS1 TorqStart Electro-Mechanical Hard Start Kit 1.5-3 Ton

The Packard TQS1 TorqStart is an electro-mechanical (EM) hard start kit designed for residential and light commercial air conditioning compressors rated from 1.5 to 3 tons (1.5–3.5 HP). By adding a start capacitor and potential relay to the compressor circuit, the TQS1 dramatically increases starting torque, reducing stress on the compressor motor and helping it start reliably even under challenging conditions such as low voltage, high head pressure, or a weak run capacitor.

Unlike PTC (positive temperature coefficient) type hard start devices, the TorqStart uses a true electro-mechanical potential relay for more consistent and reliable operation. The included bleed-down resistor safely discharges the start capacitor after each start cycle, protecting the circuit and extending component life.

Key Features:

• Electro-mechanical design — more reliable than PTC-type hard starts
• Capacitor range: 189–227 µF
• Maximum coil voltage: 502 VAC
• Simple 2-wire connection with quick-connect terminals for fast installation
• Integrated bleed-down resistor to safely discharge the capacitor after each cycle
• Compatible with reciprocating and scroll compressors
• Covers 1.5 to 3 ton / 1.5 to 3.5 HP A/C and heat pump systems

Cross-Reference / Replaces:

• Supco SK3W3
• KickStart TO-5 (TQ-5)

The Packard TQS1 TorqStart is an ideal solution for extending compressor life, improving start reliability, and reducing nuisance tripping on residential and light commercial HVAC systems.
