These relays also provide protection from phase loss – more effectively than bimetallic or eutectic alloy overload relays. Bay Power’s priority is providing you with reliable, high quality electrical hardware. Class 10 and 20 are employed for general purpose applications, whereas Class 30 is employed for loads with high inertia.
Eutectic overload relays can only be manually reset after tripping. A Westinghouse overload relay … Add item to cart for lowest price. Subscribe and get instant access to our promotions, updates, and important industry news. They get their name because the rotor resembles the rotating cylindrical “cage” that you might find in a pet squirrel or hamster cage. At ambient temperatures, both these strips will bend equally, thereby preventing the overload relay from nuisance tripping.
This may cause overheating of the motor and damage the windings of the motor. The trip class also indicates the time taken by the relay to open in an overload condition. For the best experience on our site, be sure to turn on Javascript in your browser. In the condition of an overload, the trip unit will be engaged by the primary bi-metal strip. Therefore, our standard return policy does not apply to this item.
Manufacturer's warranty still applies. We make replacing your Westinghouse overload relay as easy as possible.
Keep in touch with us! Like other induction motors, the squirrel cage motor consists of: When the motor draws excess current, it is referred to as an overload. © Copyright 2020 Bay Power Inc. All Rights Reserved. Looking for Westinghouse Overload Relays?
However, it is possible that some information in these white papers is incomplete, incorrect, or inapplicable to particular circumstances or conditions. Blowers, fans, compressors, cranes, extruders, and crushers are a few important devices equipped with electric motors. This dissimilar expansion of the bimetallic strips causes the bimetal to bend towards the metal with a low coefficient of expansion.As the strip bends, it actuates an auxiliary contact mechanism and causes the overload relay normally closed contact to open. In addition, the heaterless design is insensitive to the change in ambient temperatures, which helps minimize nuisance tripping. In the the overload relay, the eutectic alloy is contained in a tube, which is often used along with a spring loaded ratchet wheel to activate the tripping mechanism during the overload operations.
Trip Class 5 is suited for motors that demand fast tripping, whereas Class 10 is usually preferred for motors of low thermal capacity like submersible pumps.
These motors feature armortisseur windings, and work on the principle of electromagnetic induction. These relays can easily detect a loss of phase, and operate an auxiliary contact to open the motor control circuit. In many applications, the motor is installed at a location with a constant ambient temperature, and the overload relay and motor starter may be installed in a different location, which experiences different ambient temperatures.

It is important to be careful during the selection of an overload relay, because repeated tripping and reset can reduce the mechanical life of the relay and may cause damage to the motor. However, the primary bi-metal strip is the only strip that gets affected by the current flow through the heater element and the motor. This leads to the removal of the power to the motor. Disclaimer:The content provided in this white paper is intended solely for general information purposes and is provided with the understanding that the authors and publishers are not herein engaged in rendering engineering or other professional advice or services. This design helps reduce the costs and efforts of installation. We pride ourselves on the relationships we build with our customer-first mentality and the quality of our Westinghouse Overload Relays and components. * Free slots for orders with water heaters, boilers and other bulky items only. RMSO and SPO Series overload relays can be integrally mounted to Benshaw RC and RSC contactors for thermal overload …
Please check the box below to confirm you are aware that this item is for non-potable water applications only. They open the starting circuit and cut the power to the motor if it begins to draw too much current for an extended … However, the metal with a high coefficient of expansion will expand more in comparison to the metal with a low coefficient of expansion. The current flow through the motor and the temperature of the surrounding air are two factors, which may cause premature tripping. The overload relay can be reset manually, and some overload relays will reset automatically after a certain period of time. Because while the quality is high, the cost of Westinghouse Overload Relays shouldn’t be. This type of overload relay is comprised of a heater winding, a mechanical mechanism for activation of a tripping mechanism, and a eutectic alloy. Join our mailing list to receive exclusive offers and coupons. It is one of the most widely used types of electrical motors; and, is an integral part of almost 80% of the industrial applications.
The motor current passes through the small heater winding. It is expressed as H ∝ I2Rt. The overload relay is wired in series with the motor, so the current that flows to the motor when the motor is operating also flows through the overload relay. sign in. Overload relays are part of the motor starter (assembly of contactor plus overload relay). While the original Westinghouse company has not manufactured new products since being acquired by Eaton, reconditioned Westinghouse overload relays function as good as new. The above equation defines that heat produced by the winding will be directly proportional to the time period of the flow of overcurrent through the winding. This causes the circuit between the motor and the power source to open. c3controls Headquarters, USA664 State StreetBeaver, PA 15009TEL 724.775.7926FAX 724.775.5283. For product availability in your area, please verify your zip code. This function is plotted on the inverse time curve below, and is termed as the trip class. That’s why we offer a 1-year replacement warranty on all of our electrical products and solutions from the top manufacturers. After which, the motor can be restarted. Don’t get rid of them just yet.

This item is for non-potable (non-human consumption) water applications only. At this time, we do not carry this unit. 1-888-757-4774. A motor overload relay is an electro-mechanical relay that is operated by heat developed in the relay.When the level of current in a circuit reaches a preset value, the increased temperature opens a set of contacts. These motors are available in sizes ranging from fractional horsepower (HP) less than one kilowatt to 10,000’s HP (tens of megawatts). They are designed to convert electrical energy into mechanical energy. The overload relay is wired in series with the motor, so the current that flows to the motor when the motor is operating also flows through the overload … To see the price, simply add the item to your cart or Electric motors are an integral component of industrial equipment, toys, vehicles, and electronic devices.

Failure to comply with this could result in substantial property damage, severe personal injury or death.
The alloy melts due to the heat, thereby releasing the ratchet wheel, and allowing it to turn.
