CT21 series spring operated mechanism (for load switch)Detailed product description：

Overview
The CT21 type (for load switches) spring operated mechanism can be used to operate ZNF □ -10/630 outdoor high-voltage vacuum load switches, 3-63KV AC high-voltage load switches, and other load switches with equivalent closing power. Its performance complies with the latest design of our factory's improved electric mechanism GB3804CT23 series, using permanent magnet DC motor and sprocket transmission energy storage, with smooth operation, high reliability, good mechanical performance, and long service life; The manual energy storage handle is installed inside the mechanism body, avoiding the leakage of water in the original component. Additionally, the pull ring is located at the lower part of the mechanism, making it more aesthetically pleasing and suitable for use in new and old outdoor 10KV column vacuum circuit breakers. Three types of manual button operation; There are two types of closing operations: closing electromagnet and manual button operation. Method. The machinery was ordered 10000 times.

Main technical parameters of CT21 series spring operated mechanism (for load switch)
1. The energy storage motor adopts a permanent magnet single-phase DC motor, and its technical parameters are shown in the table:

model	rated voltage	Rated output power rate	Normal operating voltage
53ZY-CY	-220	≤30W	85% to 110% rated voltage

2. The opening electromagnetic wire powered by an independent power supply is used, and the technical data is shown in the table below

Rated working voltage (V)	～220V	～110V	-220V	-110V
Rated working current (A)	two point nine	four point five	two point eight	five point eight five
Rated electrical rate (W)	<638	<494	<616	<643
Coil resistance value at 20C (Ω)	27±1.6	eight point seven	78±4.78	1.8±1.1
Normal operating voltage range	65% to 120% of the rated operating voltage should be reliably tripped, Do not disconnect when the rated voltage is less than 30%
