Thermal protective relay contactor 4TM1/6, 220 V

Model: 4TM1/6

Voltage: 220 V

Connection: 2 contacts (twist "female" + 6.3 mm terminal)

Dimensions (HxWxD): 32x22x23 mm

Description

The thermal protective relay contactor 4TM1/6 is designed to reliably protect refrigerator compressors from overheating and overloads. It automatically disconnects the compressor when critical conditions are reached, preventing damage, and restores operation once parameters normalize.

Operating principle:

1. When power is supplied, the relay connects the compressor to the power supply.
2. In case of overheating or overload, the circuit opens, protecting the device from damage.
3. Once the issue is resolved, the relay returns to its original state, allowing the compressor to resume operation.

Main specifications

• Voltage and frequency: 220 V, 50-60 Hz
• Connection: 2 contacts (twist "female" + 6.3 mm terminal)
• Dimensions (HxWxD): 32x22x23 mm
• Marking: 4TM 16HP
• Manufacturer: China

Reasons for replacement

The need to replace the thermal relay may arise due to the following factors:

• Overload or overheating that caused damage to the relay.
• Physical damage to the housing or contacts.
• Wear associated with prolonged use of the device.

Regular maintenance and timely replacement of the thermal relay will help avoid compressor failures and extend the lifespan of the refrigerator.

How to choose the right part

When selecting the thermal relay 4TM1/6, pay attention to the following aspects:

• Voltage: ensure that the relay matches the voltage of your device (in this case, 220 V).
• Compatibility: check if this model is suitable for your compressor. Manufacturers often list compatible models on the packaging or in the manual.
• Dimensions: make sure the relay's dimensions fit your device to avoid installation issues.

Causes of failure and prevention methods

The main causes of thermal relay failure may include:

• Frequent overheating due to prolonged compressor operation.
• Poor quality electrical connections, which can lead to sparking.

To avoid failures, it is recommended to:

• Regularly check the condition of the compressor and its surroundings.
• Monitor the quality of electrical wiring and promptly replace damaged sections.

Replacement recommendations

Replacing the thermal relay 4TM1/6 is a process of moderate complexity. Follow these steps:

1. Disconnect the refrigerator from the power supply for safety.
2. Remove the cover to access the internal components.
3. Disconnect the old relay from the contacts, remembering or noting the connection order.
4. Install the new relay, connecting it the same way the old one was connected.
5. Check the connections for reliability and close the device cover.
6. Reconnect the refrigerator to the power supply and check its operation.

If you are unsure of your abilities, it is better to consult a professional for part replacement.
