In scenarios such as industrial production, plant power distribution, and equipment installation, the selection of electrical accessories directly affects the stability, safety, and service life of equipment operation, as well as the control of procurement costs. Many purchasers, electricians, and even industry novices are prone to some mistakes in the selection process, which not only cause the accessories to fail to work normally, but also may lead to potential safety hazards and increase later maintenance costs. Today, we will sort out the common mistakes in the selection of electrical accessories and share the correct selection methods to help you avoid pitfalls and select accurately.
Mistake 1: Only focus on price and ignore quality. In order to control costs, some purchasers prefer low-cost electrical accessories, but ignore the material, craftsmanship and testing standards of the accessories. Low-cost accessories often have problems such as poor contact of contacts, poor insulation performance, and insufficient high-temperature resistance. Long-term use is prone to faults such as short circuits and burnout, which instead increases maintenance costs and shutdown losses.
Mistake 2: Blindly pursue high-end products and ignore actual needs. Contrary to only focusing on price, some purchasers blindly choose imported high-end accessories, thinking that the higher the price, the better the quality, but ignore the actual working conditions and needs of their own equipment. For example, for low-voltage control cabinets in ordinary workshops, ordinary qualified domestic circuit breakers can meet the needs, and there is no need to spend high prices to purchase imported high-end models, resulting in cost waste.
Mistake 3: Ignore specification matching and select only based on experience. The specifications of electrical accessories (such as voltage, current, power, protection level, etc.) directly determine their adaptability. Many people select based solely on past experience without checking the specific parameters of the equipment, resulting in mismatching between accessories and equipment. For example, if the rated current of the contactor is less than the working current of the equipment, the contactor will trip and burn out frequently; if the specification of the terminal block does not match the cable diameter, it will cause loose wiring and poor contact, leading to heating hazards.
Correct selection method: First, clarify the working conditions of the equipment, including working voltage, current, power, ambient temperature, humidity, dust and water resistance requirements, etc.; second, give priority to accessories that meet national testing standards and have brand guarantees, balancing quality and cost performance; finally, check the specification parameters of the accessories to ensure they are fully compatible with the equipment. If necessary, you can consult professional and technical personnel for targeted selection suggestions.
