CT20Y Permanent Magnetic & Spring Operating Mechanism
CT20Y permanent magnetic & spring operating mechanism will be used in ZW20A-12 vacuum circuit breaker and outdoor or indoor vacuum circuit breaker with
equivalent closing power, its performances can meet requirements of GB1984 AC High Voltage Circuit Breaker and the product's Technical Conditions;
with function of motor and manual closing/opening, simple structure, safe and reliable, long service life; can take the place of CT20W spring operating mechanism,
less maintenance or even maintenance-free. Equipped with intelligence switch controller, can monitor the permanent magnetic operating mechanism coil through
electirc or micro system, to realize opening/closing, overcurrent, fast breaking, etc. multi-functions.
Working Condition
- Altitude: ≤1000m
- Ambient air temperature: -40°C~+40°C, the average temperature within 24hours ≤35 °C
- Wind speed: ≤34m/s
- Earthquake resistance capacity: ground horizontal acceleration 0.3g, ground vertical acceleration 0.15g acting three continuous sine waves at the same time, safety factor 1.67

- Maximum ice thickness: 10mm
- Operating environment: outdoor
- No operating in such places as subject to explosives, inflammables, corrosives and severe vibration
Technical Parameter
1.The permanent magnetic operating mechanism is controlled by a single coil and the spring operating mechanism is only equipped with the breaking electromagnet, technical parameter as follows:
Item | Permanent magnetic operating mechanism coil | Spring operating mechanism breaking electromagnet |
Rated operate voltage (V) | DC220V | DC220V |
Coil resistance at 20°C (Ω） | 2.3Ω | 125Ω |
2.Manual energy storage and manual breaking operation are carried out by the opening/closing handle allocated with the mechanism,the operating force less than 100 (N.m)
3.Mechanism output angle 44 degree.
4.Mechanism net weight: 25kg
5.The auxiliary switch contacts with the mechanism can pass through continuous current 10A (AC220V) and 3A (DC220V)
