RMSO-150H-113A BENSHAW Bimetallic Overload Relay Mfgd

Review BENSHAW Rmso Class Bimetallic Overload Relay Mfgd

The Benshaw RMSO-150H-113A is a 20 pole, bimetallic overload relay manufactured by Benshaw. This reliability-driven overload relay is engineered for heavy-duty applications in various industries such as power generation, oil and gas, and industrial automation fields.

The RMSO-150H-113A is specifically designed to protect motors and machinery from overloading, short-circuits, and other electrical faults. With 20 separate pole contacts, this versatile relay is capable of monitoring the electrical load of multiple circuits simultaneously, enhancing system safety and efficiency.

The bimetallic construction of the relay is the heart of its functional design. This mechanical switching element employs two materials with different linear expansion rates, which work together to actuate the contacts in response to an overload condition. The contents are securely housed within a robust enclosure made of die-cast aluminum material, ensuring excellent resistance to environmental stresses.

The relay's average current rating ranges from 15 amperes to 150 amperes, with a trip setting (Ts) of 113A 10%. An advanced design allows for easy adjustment of the trip setting via a rear-mounted dial, facilitating a streamlined, user-friendly installation process. The transformerless design further enhances the overall performance by eliminating the need for an external transformer.

Additionally, the RMSO-150H-113A comes equipped with an adjustable time delay feature, providing users with the ability to fine-tune the contact opening time to accommodate various motor and application requirements. The relay also features seven adjustable settings for discrimination of inrush and starting currents, ensuring smooth transitions during motor start-up.

The Benshaw RMSO-150H-113A offers a wide temperature operating range from -40 F to 140 F, making it a suitable choice for applications in various climatic conditions. With an insulation class of B, the relay can effectively handle the challenging electrical environments of heavy industrial applications. Furthermore, the relay's CE and RoHS approvals reflect its fully compliant status with European Union (EU) and Restriction of Hazardous Substances (RoHS) directives, providing the buyer with confidence in the product's adherence to global safety standards.

Pros and Cons of Buying Benshaw RMSO-150H-113A Overload Relay

The Benshaw RMSO-150H-113A is a 20 A, 2-pole, 5-position, reverse-acting, bimetallic overload relay manufactured by Benshaw. Below is an analysis of its advantages and disadvantages for potential buyers.

1. Robust Design: The relay is designed with a heavy-duty construction, making it suitable for various industrial applications with high electrical loads.

2. Reverse Acting: The reverse-acting feature allows the relay to act in both overload and underload situations, providing increased safety and better system protection.

3. Five Positions: The 5-position adjustable settings enable users to customize the relay for different applications, facilitating more precise control and meeting the varying requirements of different loads.

4. Bimetallic Mechanism: The bimetallic mechanism in this relay offers fast and reliable response to temperature changes, ensuring that current overloads are detected and acted upon quickly.

5. Compliance with Industry Standards: The relay conforms to several industry standards, including UL and CSA, ensuring quality and safety in various applications.

1. Dependence on Mechanical Elements: The bimetallic mechanism relies on mechanical elements, which may wear out over time and require replacement, potentially leading to additional costs and downtime.

2. Limited Application Range: Due to its constant current design, this relay may not be suitable for applications with varying voltage or requiring switch transfer characteristics.

3. Cool-Down Time: After a tripping event, the relay requires a cool-down time to reset before it can be returned to service. This can result in additional downtime for the system.

The Benshaw RMSO-150H-113Aoverload relay offers various advantages, such as a robust design, adjustable settings, and a fast response to current overloads. However, it also comes with some limitations, such as mechanical dependence and a cool-down time after a tripping event.

For applications where precise overload protection is essential, and the system can tolerate the cool-down time after tripping events, the Benshaw RMSO-150H-113A overload relay can be an excellent choice. Users should consider the cost of periodic maintenance or replacement of mechanical components when evaluating total cost of ownership. Additionally, those requiring switch transfer characteristics or applications with varying voltages should consider alternative relay options.
