Such components include block contactors and miniature contactors, as well as our circuit breakers and disconnect switches. Equipment downtime means money lost, so we'll do all that we can to work with you to get you exactly the parts you need as quickly as possible. It is available in three model ranges with different interrupting capacities and trip class 10 overload protection. Combined Shipping Policy We will combine shipments to reduce costs for customers purchasing multiple items. Manual motor starters magnetic only are equipped with an instantaneous short-circuit release only. See individual item for cost.
All items are palletized and shrink wrapped before they leave the warehouse. We've been an authorized stocking distributor for more than 20 years, and we have the knowledge and experience to help you get exactly the parts you need. As a rough guide, the lifetime of the winding isolation reduces by half each time the temperature exceeds 10° C. . We list all items to the best of our ability and aim to provide the customer with as much information as possible.
If shipping to residential address, there is an additional fee assessed by the freight company. Class designations and brief descriptions are listed below. Other terms are motor-protective circuit-breaker or simply circuit breaker. Amphenol Industrial Operations manufactures five classes of connectors to meet different requirements. Bitter End Trading is an asset recovery wholesaler specializing in new and used surplus industrial equipment.
All the information provided in this book is only general and each individual application must be handled as a specific case. We will package and weigh the entire purchase and provide an invoice, including shipping and handling. This tripping time refers to a steady symmetrical three-pole load with a 7. Thermal protective devices are overload relays and electronic, bi-metal or manual motor starters. Short-circuit protection The factory sets the instantaneous short-circuit release to a fixed multiple value of the rated operational current, thus providing a direct motor start with reliable motor protection.
Handling charges per shipment are determined by size of the item, as well as additional packing requirements on delicate instruments. Freight Shipping We have very competitive rates for shipping freight. The starting time is a function of load torque, inertia and motor torque and is influenced by the motor technology. Our service team is trained, experienced, and ready to respond to your needs. Abnormal temperature rises can be caused by overload, electrical faults, cooling problems or improper operating parameters or operation conditions.
Based on the motor parameters and voltage, either a fuse, a circuit breaker or a manual motor starter has to be used. This differentiates motors and pumps from other loads, such as heating resistors and lamps. After customers have completed their mulitple purchases they should request an invoice. Bitter End Trading is not a representative of any manufacturer listed; all names, logos, descriptions and other related information are trademarks of their respected companies or manufacturers. In compliance with international and national standards, the setting current is the rated current of the motor and not the tripping current no tripping at 1. Applications include military ground support equipment, ordnance and shipboard installations.
The protection function is realized with the following sub-functions: —— Overload protection —— Short-circuit protection —— Phase loss sensitivity The manual motor starter disconnects all phases from the line when an overload or short-circuit occurs. The trip class of a manual motor starter indicates the maximum tripping time from a cold state. Email us with your zip code for an accurate freight rate. For the switching of the motor, which occurs when starting and accelerating to normal speed, a contactor, manual motor starter or softstarter is used. The manual motor starters have a setting scale in amperes, which allows the device to be adjusted directly without any additional calculation.
These connectors represent well-proven electrical capability at an acceptable cost for most equipment where durability is important. It is a complement to the catalogue, data sheets and brochures we have for our products and will give a general overview of what to consider when working with manual motor starters. Overload protection The actual motor current of the motor to be protected has to be adjusted on the setting scale. However, even slight temperature increases will decrease the life time of an electrical engine significantly. Consequently, this starter allows differentiation between overload and short-circuit by means of separate signaling. No warranties are expressed or implied.
