948DA31B FURNAS Trane Phase Overload Relay Hold Trip

Review FURNAS Trane Phase Overload Relay Hold Trip

The Furnas 948DA31B Trane Phase Overload Relay is a crucial component in electrical systems, specifically designed for Trane HVAC (Heating, Ventilation, and Air Conditioning) units with model number 13280006. This overload relay, which holds a 71.5A holding current and trips at 80.1A, plays a significant role in ensuring the electrical circuit's safety and efficiency.

The Furnas 948DA31B is a 3-phase overload relay, which provides precise controlling capabilities to manage the current flow through the attached equipment. This overload relay ensures that the electrical current doesn't exceed a specified limit, preventing potential overheating or damage. It's particularly beneficial for HVAC systems that operate continuously, ensuring they don't consume excessive power and ultimately saving energy.

The device comes with terminal blocks for connecting wires for line, load, and neutral, which provides a secure connection basis for the HVAC system. This overload relay also offers excellent overload protection by isolating the motor from the power source once the rated current is reached or exceeded. In turn, this protects the entire electrical system against potentially costly damage and possible safety hazards.

1. 3-phase, 71.5A hold current and 80.1A trip current

The Furnas 948DA31B Trane Phase Overload Relay is an indispensable addition to any HVAC system using the Trane model number 13280006. It offers reliable and efficient overload protection for extended operation, enhancing system performance while ensuring safety and longevity.

A Detailed Analysis of buying a Furnas 948DA31B Trane Phase Overload Relay 71.5A Hold 80.1A Trip

1. **Advantages**

a. High Current Handling Capability: The Furnas 948DA31B Trane overload relay can handle currents up to 71.5A for the hold function and 80.1A for the trip function. This makes it suitable for heavy industrial loads.

b. Robust Design: Trane is known for manufacturing high-quality electrical components. The Furnas 948DA31B relay has a robust design ensuring longevity and reliability.

c. Phase Overload Protection: The primary function of this relay is phase overload protection, guarding against single-phase overloading, thus reducing chances of motor burnout.

d. Customizable: Depending on the specific application, various settings can be configured for both the hold and trip functions for optimal performance efficiency.

2. **Disadvantages**

a. Cost: Given its high capacity and capabilities, the Furnas 948DA31B Trane phase overload relay is comparatively expensive. Moreover, its replacement may require professional installation which adds to the overall cost.

b. Size and Weight: The larger size and weight of the relay could present challenges in installation, particularly in confined spaces.

3. **Conclusion**

Considering the advantages and disadvantages, the Furnas 948DA31B Trane phase overload relay is an excellent choice for applications that demand robust protection against heavy single-phase overloading with precise control over hold and trip functions. The added cost and installation challenges are justifiable given its high current handling capabilities and durability.

**Recommendation**

If you're looking for an overload relay with a smaller footprint, lower cost, or lighter weight, it may be worth considering lower current alternatives. However, if you require reliable, efficient oversizing protection for heavy industrial loads, the Furnas 948DA31B Trane phase overload relay is a valuable investment.
